1.stn LCD STN (Super Twisted Nematic Super Twist) is divided into CSTN and DSTN, which belongs to reflective LCD devices, which is less power consumption. Compared with the TFT -LCD screen, it is long in product standby time, but this is based Sacrifice other aspects at a cost. The STN screen screen is much inferior than the TFT screen. The differences between the color and brightness of the color and the brightness of the picture are particularly obvious, so the STN screen is difficult to use in the sunlight environment of outdoor light. The STN screen displays a slow response time, about 200 milliseconds, and the tail phenomenon is serious when playing animation.

The screen usually appears on the earlier low -end color screen MP3 and MP4 products. Many 4096 color screen MP3 under thousands of yuan often use this LCD panel. It has been seen in new products. Other technologies replace.
2.TFT LCD TFT (Thin Film Transistor thin film transistor) is an active matrix LCD display (AM-LCD)
One of them, the TFT -LCD screen sets a special light source on the back of the substrate, which can be “
Active “control the independent pixels on the screen, which is the origin of the so -called active matrix TFT (Active Matrix TFT). This can greatly improve the response time. Generally, the TFT reflection time is relatively fast, less than 80ms. And because TFT is an active matrix LCD, the arrangement of the liquid crystal arrangement is memory, and it will not restore the original state immediately after the current disappears.
TFT also improved STN -LCD
The phenomenon of blurring flashes (water wave pattern) effectively improves the ability to play dynamic screens. Compared with STN, TFT has excellent color saturation, color restore ability and higher contrast. The disadvantage is that it consumes more power and the production cost is relatively high. TFT LCD
LCD screen is currently the most mainstream LCD display. It is not only applied to MP3 and MP4 products, but also is more common in desktop LCD display, laptop computers, TV, mobile phones and other products. I believe everyone must be familiar with.

3.LTPS TFT-LCD LTPS (Low Temperature PolyCrystalline Silicon (Low temperature polysilicon) TFT-LCD technology, a new generation of technology products derived from TFT LCD. The LTPS screen is manufactured by adding laser treatment processes to traditional A-Si TFT-LCD panels. The laser treatment process of the LTPS screen uses the laser to melt the liquid crystal material and crystallize it. Compared with the uncountable silicon of A-SI TFT-LCD, it can achieve much faster (about 99 times) electron flows in the transistor. Speed, so as to get higher resolution and richer color. LTPS LCD provides more flexibility in design than other LCD technologies, allowing smaller transistors to placed on the LCD panel. Therefore, it minimizes the space occupied by the peripheral circuit of the screen.
The number of components in the LTPS-LCD module can be reduced by 40%, while the connection part can reduce the probability of product failure. In addition, the LTPS display has greatly improved energy consumption and durability. On the display parameter, LTPS
Low -temperature polysilicon has made great breakthroughs. The horizontal and vertical visual angles can reach 170 degrees, showing that the response time is 12ms, showing the brightness of 500 Nit, and the contrast can reach 500: 1. LTPS -LCD technology has been born for many years, and has many advantages in performance. Since the development of traditional A-SI TFT technology has matured in recent years, the manufacturing of the LTPS TFT LCD screen needs to be higher than the technology level of the traditional TFT-LCD.
The production and procurement costs of LTPS TFT LCD screens are relatively high. Therefore, it is rare to use LTPS LCD screens on the market. In 2004, Dupbao Mobile Technology launched a DP7010 MPEG4 player product, which uses a 7 -inch low -temperature polysilicon (LTPS) high -resolution wide screen (16: 9) display panel. The grade picture quality, the screen display effect is very good.

4. The biggest feature of OLEDOLED panel is that it is self -luminating, unlike TFT LCD that requires backlight, so the visibility and brightness are high, and there is no perspective problem, especially its low -driving voltage and high power saving efficiency, and the response is fast. , Light weight, thin thickness, simple structure, low cost, etc., are regarded as one of the most promising products in the 21st century. OLED is also divided into two types: active and passive as LCD. Today, the AMOLED active matrix is commonly used on mobile phones. The active display method is the same as the TFT LCD. Add a thin film transistor on the back of each OLED unit. Essence At the same time, because it is too small, OLED devices need to be higher.
