Embodiment Construction

[0027] In order to solve the problem that the existing display driving circuit must correspondingly generate two clock signals required by the data shift register and the scan shift register and input the multiple shift registers formed on the panel, the present invention provides a A switching signal generator can effectively improve the defects of too many pins of a driving circuit chip and too complicated circuits.

[0028] Such as figure 2As shown, it is a schematic diagram of the circuit structure of the switching signal generator applied to the active array display in this case. The circuit structure consists of an N-bit data line (indicated by Din in the figure), a plurality of controlled switches 20-1~n and 21- 1-m, a plurality of N-bit digital-to-analog converters 22-1-n, a thin-film transistor array 23, a first switching signal generator 24, and a second switching signal generator 25.

[0029] The first switching signal generator 24 is composed of at least one set ...

Abstract

The switching signal generator is used in an active array display, said active array display includes a signal line and several controlled switches, and said switching signal generator at least contains a delay unit group, said delay unit group signal is connected with several controlled switches, and is used for receiving an original switching signal and producing several switching signals to respectively output them to said several controlled switches, and between adjacent switching signals there is a fixed phase delay, so that said several controlled switches can be coducted in turn, and the signals on the signal line can be outputted in turn.

Description

technical field [0001] The invention relates to a switch signal generator, especially a switch signal generator applied to an active array 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 known to the user 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 screen size of the display, the volume of the traditional picture tube display itself has also become q...
