Low TFT-Character LCD Modules technology introduction

Low-temperature polysilicon thin film transistors (polysilicon TFT) technology for high-definition LCD remains hopeful, but just want to process engineers have driven approach to improve the structure and the job today, South Korea, a company invented a technology that can speed up ratio ever brighter, higher-resolution monitor the launch. 256x64 oled

In the traditional design of active matrix LCD, the thin film transistor is made of amorphous silicon (a-Si) formed. Produced by the switching transistor is used as each pixel. These designs require personal computer can convert the signal into a suitable control of the display and pixel amplitudes of additional circuitry. Because conventional transistors can not be used to drive the pixel switches, IC manufacturers must be added to the customer's driver and scan functions screen. Amorphous silicon transistors also limits the size and functionality of the lighting per square inch can be the number of pixels. Result, today's PC using a-Si TFT LCD with every square inch from 60-90 pixels (PPi) range of pixel density. Although access to high resolution of about 200PPi a-Si TFT-LCD has few, if using an external driver IC, there will be constrained to limit the production of these displays commercial possibilities.
On the other hand, has been able to produce more than 200PPi resolution low-temperature polysilicon (LTPS) TFT-LCD to. For comparison purposes, consider the typical human eye is able to analyze the highest resolution about 350PPI. Better because the process can be eliminated and the display driver IC difference between the thousands of tape automated bonding, which can reduce the cost and improve the reliability of the display. SPI oled
