how tft lcd works pricelist
LCD panel prices have risen for 4 months in a row because of your home gaming? Since this year, the whole LCD panel market has smoked. Whether after the outbreak of the epidemic, LCD panel market prices rose for four months, or the panel giants in Japan and South Korea successively sold production lines, or the Chinese mainland listed companies frequently integrated acquisition, investment, and plant construction, all make the industry full of interesting.
LCD panel prices are already a fact. Since May this year, LCD panel prices have risen for four months in a row, making the whole industry chain dynamic. Why are LCD panels going up in price in a volatile 2020? The key factor lies in the imbalance between supply and demand.
The price of LCDS for large-size TVs of 70 inches or more hasn’t budged much. In addition, LTPS screens and AMOLED screens used in high-end phones have seen little or no increase in price.
As for October, LCD panel price increases are expected to moderate. The data shows that in October 32 inches or 2 dollars; Gains of 39.5 to 43 inches will shrink to $3;55 inches will fall back below $10; The 65-inch gain will narrow to $5.
During the epidemic, people stayed at home and had no way to go out for entertainment. They relied on TV sets, PCS, and game consoles for entertainment. After the resumption of economic work and production, the market of traditional home appliances picked up rapidly, and LCD production capacity was quickly digested.
However, due to the shutdown of most factories lasting 1-2 months during the epidemic period, LCD panel production capacity was limited, leading to insufficient production capacity in the face of the market outbreak, which eventually led to the market shortage and price increase for 4 consecutive months.
In fact, the last round of price rise of LCD panels was from 2016 to 2017, and its overall market price has continued to fall since 2018. Even in 2019, individual types have fallen below the material cost, and the whole industry has experienced a general operating loss. As a result, LCD makers have been looking for ways to improve margins since last year.
A return to a reasonable price range is the most talked about topic among panel makers in 2019, according to one practitioner. Some manufacturers for the serious loss of the product made the decision to reduce production or even stop production; Some manufacturers planned to raise the price, but due to the epidemic in 2020, the downstream demand was temporarily suppressed and the price increase was postponed. After the outbreak was contained in April, LCD prices began to rise in mid-to-late May.
In fact, the market price of LCD panels continued to decline in 2018-2019 because of the accelerated rise of China’s LCD industry and the influx of a large number of local manufacturers, which doubled the global LCD panel production capacity within a few years, but there was no suitable application market to absorb it. The result of excess capacity is oversupply, ultimately making LCD panel prices remain depressed.
Against this background, combined with the impact of the epidemic in 2020, the operating burden of LCD companies in Japan and South Korea has been further aggravated, and it is difficult to make profits in the production of LCD panels, so they have to announce the withdrawal of LCD business.
business in June 2022. In August, Sharp bought JDI Baishan, a plant in Ishikawa prefecture that makes liquid crystal display panels for smartphones. In early September, Samsung Display sold a majority stake in its SUZHOU LCD production plant to Starlight Electronics Technology, a unit of TCL Technology Group. LGD has not only pulled out of some of its production capacity but has announced that it will close its local production line in 2020. According to DSCC, a consultancy, the share of LCD production capacity in South Korea alone will fall from 19% to 7% between 2020 and 2021.
It is worth mentioning that in industry analysis, in view of the fact that Korean companies are good at using “dig through old bonus – selling high price – the development of new technology” the cycle of development mode, another 2020 out of the LCD production capacity, the main reason may be: taking the advantage of China’s expanding aggressively LCD manufacturers, Korean companies will own LCD panel production line hot sell, eliminating capacity liquid to extract its final value, and turning to the more profitable advantage of a new generation of display technologies, such as thinner, color display better OLED, etc. Samsung, for example, has captured more than 80% of the OLED market with its first-mover advantage.
From the perspective of production capacity, the launch of LCD tracks by major manufacturers in Japan and South Korea must reduce some production capacity in the short term, which to some extent induces market price fluctuations. In the long run, some of the Japanese and Korean LCD production capacity has been bought by Chinese manufacturers, coupled with frequent investment in recent years, the overall capacity is sure to recover as before, or even more than before. But now it will take time to expand the production layout, which more or less will cause supply imbalance, the industry needs to be cautious.
The LCD panel industry started in the United States and then gradually moved to Japan, South Korea, China, and Taiwan. At present, the proportion of production capacity in The Chinese mainland has reached 52% in 2020, and there are leading LCD panel products in China represented by BOE, Huxing Optoelectronics. Meanwhile, the production capacity layout of BOE, Huike, Huxing Optoelectronics, and other manufacturers has been basically completed, making industrial integration a necessity.
On the one hand, South Korean enterprises out of the LCD track, the domestic factory horse enclosure, plant expansion action. While LCDs may not sell as well as “upstart” flexible screens, respondents believe they are still strong enough in the traditional home appliance market to warrant continued investment. Zhao Bin, general manager of TCL Huaxing Development Center, has said publicly that the next-generation display technology will be mature in four to five years, but the commercialization of products may not take place until a decade later. “LCD will still be the mainstream in this decade,” he said.
On the other hand, there is no risk of neck jam in China’s LCD panel industry, which is generally controllable. In mainland China, there will be 21 production lines capable of producing 32-inch or larger LCD panels by 2021, accounting for about two-thirds of the global total. In terms of the proportion of production capacity, the Chinese mainland accounted for 42% of the global LCD panel in 2019, 51% this year, and will continue to climb to 63% next year.
Of course, building factories and expanding production cannot be accomplished overnight. In the process of production capacity recovery, it is predicted that there will be several price fluctuations, and the cost may be passed on to the downstream LCD panel manufacturers or consumers when the price rises greatly, which requires continuous attention.
A lot of consumers wonder how manufacturers determine the LCD display panel prices. After all, display solutions such as TFT LCDs and HMI touch screens do not always come cheap. And sometimes, a few products that can indeed be purchased for lower prices may come with several quality issues.
Hence, we’ve rounded up a list of factors that influence how to display modules such as TFTs, LCD, and touch screens are priced. You can also use these factors to evaluate to whom you should place your next orders for your display solutions.
LCD fluids are used in altering the light orientation passing through glass substrates. Hence, this causes the panel’s active pixels to darken. Different kinds of LCD panel fluids provide unique characteristics and change a panel’s viewing angle, temperature range, and display clarity.
Another characteristic of this fluid is that it works well even in colder temperatures. It’s because TN fluid has the quickest response time among the other LCD fluid types.
TN fluid is considered the cheapest LCD fluid type. However, this doesn’t mean that TN isn’t widely used. The display technology is greatly utilized in digital clocks, pagers, and gas pumps.
LCD modules with STN fluid enjoy a wider display angle, greater multiplexing, higher image contrast, and sharper response than devices using TN fluids. However, modules with STN fluids may have slower response times when used in lower temperatures due to the fluid freezing inside the device.
STN fluid falls under the moderately cheap LCD module price. Furthermore, STN fluid is widely utilized in several monochrome LCD devices such as POS machines, inexpensive feature phones, and informational screens of some devices.
CSTN is a bit pricier than TN and STN fluids. But it’s a good choice if you need to display color images on your LCD device. In fact, a lot of color feature phones use CSTN as an alternative to the TFT displays, saving almost half the manufacturing costs.
In terms of cost, the LCD display module price of a unit with FSTN is higher compared to TN and STN. But this is concerning the better visual quality that FSTN offers.
To cap off this part, the fluids used in a screen is a big factor in determining the overall LCD screen display panel price. As you can see, the four fluid types often used in LCD screens rise in costs with respect to the visual quality produced by each technology.
The temperature range in which LCD screen displays may work varies intensely. Some displays continue to work at optimal performance even when used in cold or hot outdoor temperatures. Lower-quality LCD panels may start having glitches at the slightest change of temperature and humidity. Hence, the temperature range may have a huge impact on the LCD display panel price as well.
Now, most LCD screen panels don’t experience such temperature extremes. In fact, a typical LCD TV can operate properly between approximately o°C and 32°C (32° – 90° F). Meanwhile, other screen modules (usually the industrial-grade ones) have unique capabilities to work in even more extreme ends of the temperature scale.
If you want to look for the most cost-effective type of LCD panel for your device, then you must consider the following standard LCD unit temperature types:
Normal temperature units work well in environments that have indoor temperatures at approximately 20-35°C (68-95°F). Some LCD modules may work well above up to 50°C (122°F). Such LCD modules can be used in daily settings by the typical consumer public.
LCD units under this type are made to withstand lower and higher temperature ranges. Extreme operating temperatures may range anywhere from -30°C to 85°C (-22-185°F). Most LCD modules with wide/extreme temperature capabilities are used in extremely cold areas such as Artic places and ski resorts, as well as humid and moisture-rich hot outdoor areas.
Generally, the LCD module price goes up if the entire display unit can withstand higher temperature ranges. Those who can operate under normal temperature ranges only are usually cheaper.
Hence, you must consider the places where you’ll be installing your LCD display devices. You can’t just use cheaper LCD modules for an industrial-grade display machine. Treat your LCD panel as an investment and select a panel that will yield better screen performance that’ll last several years for you and your business.
It’s an unspoken rule, but monochrome modules are generally cheaper than color-capable ones. However, color-capable display modules may also have cost variations depending on their display capabilities.
Color LCDs have three subpixels that hold red, blue, and green color filters. Each subpixel can have as much as 256 color shades, depending on the variation and control of the voltage applied to it.
Now, when you combine 256 shades of both red, blue, and green subpixels, color LCDs can display a color palette of up to 16.8 million colors. And all these are made possible by millions of transistors etched onto the glass modules.
Display size also plays a large role in an LCD device’s color capability. Smaller screens need fewer pixels and transistors since they have smaller display sizes. These screens are also less costly to make. Now, larger screens with high color resolution and huge display sizes require more transistors and pixels, justifying the higher prices of such monitors.
We’ve explained the following factors at length for both public consumers and business clients to understand the variations in TFT, LCD, and HMI touch screen prices.
Cheap doesn’t necessarily mean low-quality. Also, expensive options aren’t always a wise choice, either. You can maximize your buying or manufacturing options if you know how to compare LCD modules and panels depending on the specifications you truly need for your display machines and devices.
In this Arduino touch screen tutorial we will learn how to use TFT LCD Touch Screen with Arduino. You can watch the following video or read the written tutorial below.
As an example I am using a 3.2” TFT Touch Screen in a combination with a TFT LCD Arduino Mega Shield. We need a shield because the TFT Touch screen works at 3.3V and the Arduino Mega outputs are 5 V. For the first example I have the HC-SR04 ultrasonic sensor, then for the second example an RGB LED with three resistors and a push button for the game example. Also I had to make a custom made pin header like this, by soldering pin headers and bend on of them so I could insert them in between the Arduino Board and the TFT Shield.
Here’s the circuit schematic. We will use the GND pin, the digital pins from 8 to 13, as well as the pin number 14. As the 5V pins are already used by the TFT Screen I will use the pin number 13 as VCC, by setting it right away high in the setup section of code.
I will use the UTFT and URTouch libraries made by Henning Karlsen. Here I would like to say thanks to him for the incredible work he has done. The libraries enable really easy use of the TFT Screens, and they work with many different TFT screens sizes, shields and controllers. You can download these libraries from his website, RinkyDinkElectronics.com and also find a lot of demo examples and detailed documentation of how to use them.
After we include the libraries we need to create UTFT and URTouch objects. The parameters of these objects depends on the model of the TFT Screen and Shield and these details can be also found in the documentation of the libraries.
So now I will explain how we can make the home screen of the program. With the setBackColor() function we need to set the background color of the text, black one in our case. Then we need to set the color to white, set the big font and using the print() function, we will print the string “Arduino TFT Tutorial” at the center of the screen and 10 pixels down the Y – Axis of the screen. Next we will set the color to red and draw the red line below the text. After that we need to set the color back to white, and print the two other strings, “by HowToMechatronics.com” using the small font and “Select Example” using the big font.
So the drawDistanceSensor() custom function needs to be called only once when the button is pressed in order to draw all the graphics of this example in similar way as we described for the home screen. However, the getDistance() custom function needs to be called repeatedly in order to print the latest results of the distance measured by the sensor.
Here’s that function which uses the ultrasonic sensor to calculate the distance and print the values with SevenSegNum font in green color, either in centimeters or inches. If you need more details how the ultrasonic sensor works you can check my particular tutorialfor that. Back in the loop section we can see what happens when we press the select unit buttons as well as the back button.
Ok next is the RGB LED Control example. If we press the second button, the drawLedControl() custom function will be called only once for drawing the graphic of that example and the setLedColor() custom function will be repeatedly called. In this function we use the touch screen to set the values of the 3 sliders from 0 to 255. With the if statements we confine the area of each slider and get the X value of the slider. So the values of the X coordinate of each slider are from 38 to 310 pixels and we need to map these values into values from 0 to 255 which will be used as a PWM signal for lighting up the LED. If you need more details how the RGB LED works you can check my particular tutorialfor that. The rest of the code in this custom function is for drawing the sliders. Back in the loop section we only have the back button which also turns off the LED when pressed.
In order the code to work and compile you will have to include an addition “.c” file in the same directory with the Arduino sketch. This file is for the third game example and it’s a bitmap of the bird. For more details how this part of the code work you can check my particular tutorial. Here you can download that file:

A TFT display is a form of Liquid Crystal Display with thin film transistors for controlling the image formation. The TFT technology works by controlling brightness in red, green and blue sub-pixels through transistors for each pixel on the screen.
Compare IPS vs TFT displays - the TFT display is the display of choice for industrial designs, but it can have its limitations. A newer technology called IPS (in plane switching) offers better viewing angles and colours, but is it really the best choice - we discuss benefits and negatives of both types of TFT display.
In this guide we’re going to show you how you can use the 1.8 TFT display with the Arduino. You’ll learn how to wire the display, write text, draw shapes and display images on the screen.
The 1.8 TFT is a colorful display with 128 x 160 color pixels. The display can load images from an SD card – it has an SD card slot at the back. The following figure shows the screen front and back view.
This module uses SPI communication – see the wiring below . To control the display we’ll use the TFT library, which is already included with Arduino IDE 1.0.5 and later.
The TFT display communicates with the Arduino via SPI communication, so you need to include the SPI library on your code. We also use the TFT library to write and draw on the display.
The 1.8 TFT display can load images from the SD card. To read from the SD card you use the SD library, already included in the Arduino IDE software. Follow the next steps to display an image on the display:
Note: some people find issues with this display when trying to read from the SD card. We don’t know why that happens. In fact, we tested a couple of times and it worked well, and then, when we were about to record to show you the final result, the display didn’t recognized the SD card anymore – we’re not sure if it’s a problem with the SD card holder that doesn’t establish a proper connection with the SD card. However, we are sure these instructions work, because we’ve tested them.
In this guide we’ve shown you how to use the 1.8 TFT display with the Arduino: display text, draw shapes and display images. You can easily add a nice visual interface to your projects using this display.
When compared to the ordinary LCD, TFT LCD gives very sharp and crisp picture/text with shorter response time. TFT LCD displays are used in more and more applications, giving products better visual presentation.
TFT is an abbreviation for "Thin Film Transistor". The colorTFT LCD display has transistors made up of thin films of Amorphous silicon deposited on a glass. It serves as a control valve to provide an appropriate voltage onto liquid crystals for individual sub-pixels. That is why TFT LCD display is also called Active Matrix display.
A TFT LCD has a liquid crystal layer between a glass substrate formed with TFTs and transparent pixel electrodes and another glass substrate with a color filter (RGB) and transparent counter electrodes. Each pixel in an active matrix is paired with a transistor that includes capacitor which gives each sub-pixel the ability to retain its charge, instead of requiring an electrical charge sent each time it needed to be changed. This means that TFT LCD displays are more responsive.
To understand how TFT LCD works, we first need to grasp the concept of field-effect transistor (FET). FET is a type of transistor which uses electric field to control the flow of electrical current. It is a component with three terminals: source, gate, and drain. FETs control the flow of current by the application of a voltage to the gate, which in turn alters the conductivity between the drain and source.
Using FET, we can build a circuit as below. Data Bus sends signal to FET Source, when SEL SIGNAL applies voltage to the Gate, driving voltage is then created on TFT LCD panel. A sub-pixel will be lit up. A TFT LCD display contains thousand or million of such driving circuits.

TFT-LCDs are used in flat-panel televisions as well as computer monitors, laptop computers, mobile phones, personal digital assistants, and other devices. Plaintiffs charged that defendants conspired to raise and fix the prices of TFT-LCD panels and certain products containing those panels for over a decade, resulting in overcharges to purchasers of those panels and products.
In March 2010, the Court certified two nationwide classes of persons and entities that directly purchased TFT-LCDs from January 1, 1999 through December 31, 2006, one class of panel purchasers, and one class of buyers of laptop computers, computer monitors, and televisions that contained TFT-LCDs.
To interface TFT LCD Display with Arduino, for designing custom HMI TFT LCD Display provide rich colours, detailed images, and bright graphics with their full-colour RGB mode it comes in different pixels 128 x 160 pixels, 320×240 pixels and many more.
In this tutorial, we’ll interface the 1.8 TFT LCD display with Arduino Uno. You’ll learn how to interface the TFT LCD with Arduino to write text on this LCD. This tutorial presents the coding, wiring diagram and components list required for the LCD display.
Creating an interface between the user and the system is very important. This interface can be created by displaying useful data, and menus. There are several components to achieving this. LEDs, 7-segments, OLEDs, and full-color TFT LCDs. The right component for your projects depends on the amount of data to be displayed, and the type of user interaction.
TFT LCD is a variant of a liquid-crystal display (LCD) that uses thin-film-transistor (TFT) technology to improve image qualities such as addressability and contrast. In the case of Arduino, the processor frequency is low. So it is not possible to display complex and high-speed motions. Therefore, full-colour TFT LCDs can only be used to display simple data and commands. This TFT has 128 x 160 pixels. 1.8 TFT display can load images from an SD card. It has an SD card slot at the back. You can see the front and back views of the TFT LCD in the figures below.
TFT is an abbreviation of “Thin Film Transistor”. It has transistors made up of thin films of Amorphous silicon. It serves as a control valve to provide an appropriate voltage onto liquid crystals for individual sub-pixels. The working principle is very simple the TFT LCD composes of many pixels that can emit light of any colour. The desired image achieves by controlling each pixel to display the corresponding colour. In TFT LCD, the backlight technology is generally used. In order to accurately control the colour and brightness of each pixel, it is necessary to install a shutter-like switch after each pixel. When the “blinds” are opened, light can pass through them. When the shutters are closed, light cannot pass through them.
This is the section before setup which uses for globe variables defining and libraries additions. TFT.h is the library for TFT LCD Display and uses for writing and drawing on the display. The TFT display communicates with the Arduino via SPI communication, so you need to include the SPI library.
This is the setup section in which Serial.begin(9600) initialize. TFTscreen.begin() is use to initialize the library. TFTscreen.background(0, 0, 0) is use to customize the screen background color here TFTscreen.background(0, 0, 0) means the background colour is black. TFTscreen.setTextSize(2) is use to set the font size.
In the loop section first, we will print the “Hi_peppe8o!” in the centre of the LCD and this will be in three different colours (Red, Green, Blue) you can choose any colour using the different colour codes. After 300 milliseconds a straight line will be displayed, after 300 milliseconds a square will be displayed, after 300 milliseconds a circle will be displayed, and after 300 milliseconds screen will be black/ erase and these all shapes and the text will be repeated in the void loop.
The LCD displays the text of “Hi_peppe80” and after that displays the line, square, and circle and then erases everything after completing this sequence. The command used for clearing all the data is TFTscreen.background(0,0,0):
