Problems solved by technology

[0016] Furthermore, the conventional thin film transistor array 100 and the driving circuit cannot be completed simultaneously in a single process due to the different processing procedures.
Therefore, the thin film transistor array 100 and the driving circuit are two separate devices, and wiring is used to connect the thin film transistor array 100 and the driving circuit. Therefore, the manufacturing process must cost a relatively high manufacturing cost.

Embodiment Construction

[0053] In order to solve the shortcomings caused by the structure of common liquid crystal displays, the present invention provides a driving device and method for liquid crystal displays, which can effectively improve the effect of long delay time of charging and discharging of resistors and capacitors on the performance of liquid crystal displays.

[0054] Due to the progress of the manufacturing process, the polysilicon structure can be formed by using a laser annealing (Laser Annealing) process in a low temperature environment. Therefore, the electrical characteristics of the thin film transistor can be greatly improved by using the low temperature polysilicon (Low Temperature Poty-Si) manufacturing process, and the driving circuit can be directly formed on the glass substrate where the thin film transistor array is located.

[0055] Please refer to figure 2 , the figure shows the structure of the liquid crystal display of the present invention. The liquid crystal display...

Abstract

A drive device and drive method for LCD is characterized by use of serial input and parallel output. When the digital displaying signals are serially input, they are temporaily stored in high-speed SRAM. As the SRAM needs very short access time, it only takes the charge-discharge time of resistor and capacitor for updating a row scanning line, so speeding up the picture updating. In addition, the influence of the delay time caused by said charge-discharge on efficacy of LCD is eliminated.

Description

technical field [0001] The invention relates to a liquid crystal display, in particular to a driving device and a driving method of the liquid crystal display. Background technique [0002] With the advancement of science and technology, the working speed and efficiency of computer equipment are developing rapidly. No matter at work or at home, people's dependence on computers is also greatly increased than before when dealing with affairs. Among them, the display in the computer equipment is the most direct bridge for the computer to communicate with the user. All the information that the computer itself wants to inform the user can be directly let the user know through the display. Therefore, people not only have higher requirements on the working speed and performance of computers, but also have higher requirements on display quality. [0003] In the past, with the increase of the display size of the display, the volume of the traditional display itself has also become q...
