According to TrendForce research, weak terminal demand debuting at the start of this year has led to a steady uptick in inventory pressure. In order to effectively control inventory, IC stocking momentum has trended conservative. Demand also reversed quickly for peripheral ICs that were in short supply in 2021 such as driver ICs, Tcons, and PMICs for panels, causing panel makers" demands on panel driver IC pricing to drop even more in 3Q22. With supply and demand imbalanced and inventory high, the driver IC price drop is expected to expand to 8~10% in 3Q22, and prices falling all the way until the end of the year cannot be ruled out.

TrendForce further stated, in order to consolidate supply-side momentum, Chinese panel driver IC vendors are more willing to meet the requirements of panel manufacturers, with price concessions reaching 10~15%. Since it will be difficult for demand to bounce back in the short-term, a sustained decline in panel driver IC pricing cannot be ruled out and it is very likely that prices will return to the beginning of their run in 2019 faster than expected.

Despite sluggish demand in the terminal market and increasing inventory among panel makers and panel driver ICs, for foundries with their diversified product portfolios, even when demand for panel driver ICs had previously been revised downward in the short-term, foundries still adjusted their product mixes accordingly, utilized vacated production capacity in multiple ways, and effectively allocated and maintained utilization rate.

Driven by a shortage of chips in the past two years, foundry pricing has continued to rise in the last few quarters and has remained at a high level thus far. However, driving IC manufacturers are now facing requests from downstream customers to reduce prices. Pincered by upstream price hikes, these companies have been forced to temper wafer input planning. Even the content of LTA (Long term agreement) supply contracts signed with foundries may need to be renegotiated. When panel driver IC wafer input is greatly reduced and the adjustment of other product mixes cannot bridge the production capacity gap, the overall utilization rate of fabs is likely to see disruption in 2H22.

In summary, TrendForce believes that for fabs, panel driver ICs are less profitable than other applications but they are one of the most efficient products used by fabs to round out capacity. After driver ICs encounter a sharp drop in pricing and wafer input plans are diminished in 3Q22, it is subsequently necessary to observe whether foundry pricing remain the same as in 2Q22, or be moderately reduced to maintain a high utilization rate.

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.

For this tutorial I composed three examples. The first example is distance measurement using ultrasonic sensor. The output from the sensor, or the distance is printed on the screen and using the touch screen we can select the units, either centimeters or inches.

The third example is a game. Actually it’s a replica of the popular Flappy Bird game for smartphones. We can play the game using the push button or even using the touch screen itself.

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.

As the code is a bit longer and for better understanding I will post the source code of the program in sections with description for each section. And at the end of this article I will post the complete source 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.

Next we need to define the fonts that are coming with the libraries and also define some variables needed for the program. In the setup section we need to initiate the screen and the touch, define the pin modes for the connected sensor, the led and the button, and initially call the drawHomeSreen() custom function, which will draw the home screen of the program.

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.

Now we need to make the buttons functional so that when we press them they would send us to the appropriate example. In the setup section we set the character ‘0’ to the currentPage variable, which will indicate that we are at the home screen. So if that’s true, and if we press on the screen this if statement would become true and using these lines here we will get the X and Y coordinates where the screen has been pressed. If that’s the area that covers the first button we will call the drawDistanceSensor() custom function which will activate the distance sensor example. Also we will set the character ‘1’ to the variable currentPage which will indicate that we are at the first example. The drawFrame() custom function is used for highlighting the button when it’s pressed. The same procedure goes for the two other buttons.

drawDistanceSensor(); // It is called only once, because in the next iteration of the loop, this above if statement will be false so this funtion won"t be called. This function will draw the graphics of the first example.

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:

drawDistanceSensor(); // It is called only once, because in the next iteration of the loop, this above if statement will be false so this funtion won"t be called. This function will draw the graphics of the first example.

New charge-recycling structure and driving scheme for TFT-LCD source-driver IC application are proposed. The number of additional switches for the charge recycling is greatly reduced. An experimental prototype 6-bit source driver with five-level sevenphase charge recycling implemented in a 0.35-μm CMOS technology demonstrates that the quiescent current is only 3.1 mA, dynamic power saving is 75 %, and the settling time, which includes the charge-recycling and data driving, is within 25 μs.
