tn lcd display quotation

Dr Pan: Hello, Greg. TN is the abbreviation for Twisted Nematic. The main difference between TN, HTN, STN and FSTN LCD is the view angle. From the definition, the maximum view angle of TN LCD is 90°. Take this TN positive LCD for example. The view angle is 6 o’clock direction and it can be seen very clearly in the 6 o’clock direction and the front side.

When it is a positive and reflective display, it can display without LED backlight; when it is a positive and transmissive/ transflective display, it can’t display without LED backlight, the background color is grey and the letters are black.

When it is a negative and transmissive/ transflective display, it can’t display without LED backlight, the background color is purple-black, different colors from different view angle, and the color of the letters is the color of LED backlight.

By the way, no matter it is a positive or negative display, the background color is affected by the color of LED backlight on some level. That is why the color of LED backlight is usually white.

Theoretically, we can add a blue film to TN negative LCD, it may look like this. Actually, from our experience, no one has done it before since HTN or STN negative LCD with blue background looks better with wider view angle.

TN LCD is the most commonly used since it is the cheapest. The maximum COM is 4, so it can’t display too many segments, and it can’t be used in the high end devices. But it performs very well in the simple display content: calculator and alarm clock.

Dr Pan: Hello, Greg. COG is the abbreviation for chip on glass. It is a technology, which IC is bonded directly onto ITO glass. COG technology is usually used in small size dot matrix monochrome LCD module and TFT LCD module.

NO.1, it can greatly reduce the size of the LCD module because it doesn’t have PCB and it can be as thin as 2.0mm (maybe thinner). The thinner the more expensive.

NO.3, it is cost effective over COB LCD and can totally replace COB LCD in function, especially in graphic LCD modules, because it reduces the number of IC.

NO.4, for some dot matrix LCD modules, it is not possible to apply COB LCD technology because it is too crowded to place so many points on the view area. COG LCD is an economical and feasible solution because the pitch is smaller .

Liquid Crystal Display (LCD) screens are a staple in the digital display marketplace and are used in display applications across every industry. With every display application presenting a unique set of requirements, the selection of specialized LCDs has grown to meet these demands.

LCD screens can be grouped into three categories: TN (twisted nematic), IPS (in-plane switching), and VA (Vertical Alignment). Each of these screen types has its own unique qualities, almost all of them having to do with how images appear across the various screen types.

This technology consists of nematic liquid crystal sandwiched between two plates of glass. When power is applied to the electrodes, the liquid crystals twist 90°. TN (Twisted Nematic) LCDs are the most common LCD screen type. They offer full-color images, and moderate viewing angles.

TN LCDs maintain a dedicated user base despite other screen types growing in popularity due to some unique key features that TN display offer. For one,

TN TFTs remain very popular among competitive PC gaming communities, where accuracy and response rates can make the difference between winning and losing.

VA, also known as Multi-Domain Vertical Alignment (MVA) dislays offer features found in both TN and IPS screens. The Pixels in VA displays align vertically to the glass substrate when voltage is applied, allowing light to pass through.

Displays with VA screens deliver wide viewing angles, high contrast, and good color reproduction. They maintain high response rates similar to TN TFTs but may not reach the same sunlight readable brightness levels as comparable TN or IPS LCDs. VA displays are generally best for applications that need to be viewed from multiple angles, like digital signage in a commercial setting.

IPS is superior in contrast, brightness, viewing angles, and color representation compared to TN screens. Images on screen retain their quality without becoming washed out or distorted, no matter what angle they’re viewed from. Because of this, viewers have the flexibility to view content on the screen from almost anywhere rather than having to look at the display from a front-center position.

IPS displays offer a slightly lower refresh rate than TN displays. Remember that the time for pixels to go from inactive to active is measured in milliseconds. So for most users, the difference in refresh rates will go unnoticed.

Based on current trends, IPS and TN screen types will be expected to remain the dominant formats for some time. As human interface display technology advances and new product designs are developed, customers will likely choose IPS LCDs to replace the similarly priced TN LCDs for their new projects.

The basic LCD cell has no readily discernible optical characteristics and looks transparent under any condition. But if a piece of properly oriented linear polarizer (such as those found in polarized sunglasses) is placed on each glass surface, the basis of the cell"s display properties is provided.

They first position a display"s top polarizer in phase with polarized sunglasses (which are always oriented in one standard direction) that viewers might wear; otherwise, viewing the display while wearing sunglasses would inadvertently extinguish it.

Users often backlight such "transmissive" displays with any convenient source - incandescent, fluorescent, or neon, for example - or with ambient light.

TN liquid crystals work very well in multiplex applications, however, it is important to understand the restraints that multiplexing applies to the display so that they can be properly implemented.

The most important thing to remember in multiplexing displays is that the elements are all interconnected, and there is a cross-talk problem which must be addressed.

In effect, this makes the effective drive voltage on the display a function of "n," or the number of lines it is multiplexing. So the higher the multiplex ration, the poorer the viewing angle and contrast ratio.

If the LCD panel breaks, do not get the liquid crystal in your mouth. In case of contact with your skin or clothes, wash it off immediately with soap and water.

When soldering displays with pins, avoid excessive heat. Keep the soldering temperature between 260°C and 300°C and apply heat for no more than 5 seconds. Never use wave or reflow soldering. Cover the surface of the LCD to avoid flux spatter. Remove flux residues afterward.

Do not use DC voltage to drive the LCD and keep the voltage within the specified limit. Excess voltage will shorten the display"s life. Within limit, the viewing angle can be fine tuned by varying the voltage (especially for STN). Response time will increase as the temperature decreases.

TFT displays are full color LCDs providing bright, vivid colors with the ability to show quick animations, complex graphics, and custom fonts with different touchscreen options. Available in industry standard sizes and resolutions. These displays come as standard, premium MVA, sunlight readable, or IPS display types with a variety of interface options including HDMI, SPI and LVDS. Our line of TFT modules include a custom PCB that support HDMI interface, audio support or HMI solutions with on-board FTDI Embedded Video Engine (EVE2).

At present, as LCD technology continues to mature, competition in the LCD LCD market is becoming more and more fierce, and each quotation is different. This is nothing more than a troublesome thing for customers who purchase products. What are the factors that affect the lcd module price?

LCD displays are divided into many types, such as TN LCD, IPS LCD, high-brightness LCD, etc. The prices of LCD LCDs with different specifications are entirely different, so that LCD LCD manufacturers will quote the required specifications of the LCD LCD display.

LCD liquid crystal display mainly comprises several key raw materials of LCD liquid crystal display glass panel, backlight, IC, and FPC. Each raw material has different specifications and qualities, which will directly affect the price of LCD display. Take the backlight as an example. The price of LED lamp beads can vary from 5 to 15 yuan. The number of lamp beads, ordinary lamp beads, or dual-core lamps has a price difference. These will directly affect the LCD liquid crystal display cost and thus affect the price.

Different LCD liquid crystal display application industries will have different solutions. Customers need to choose different raw materials according to different solutions, and the corresponding LCD liquid crystal display prices will vary. For example, Proculus Technologies will provide corresponding solutions according to the different industries in the smart terminal.

The factors affecting the price of LCD display are summarized above. In addition to the price of LCD screens, which are more concerned by customers, it is also important to find strong LCD screen manufacturers. Proculus Technologies focuses on providing standard and customized display products and displays technology solutions, which are trustworthy. Before buying an LCD screen, give priority to Proculus!
