Problems solved by technology

[0012] However, the aforementioned drive circuit row and column shift registers are all fixed-digit registers, and a drive circuit can only drive FPDs of a certain scale (the scale refers to the row and column pixels of the display device), which is not universal.
Since the specifications of FPDs vary widely, a dedicated drive circuit must be developed for each size of FPD, which wastes a lot of manpower, material resources and time.

Embodiment Construction

[0032] According to a preferred embodiment of the present invention, the driving circuit has 64 row and 64 column outputs. There are many control terminals, so that its controller can be controlled conveniently and flexibly, and can be cascaded and expanded through the cascading enabling terminal 16 to meet larger-scale FPDs (the inter-row cascading and inter-column cascading of this module are respectively The maximum support is 4), the column number input terminal 82 and the row number input terminal 81 can respectively adjust the number of row scanning electrodes and column signal electrodes output by the driving circuit according to the scale of the FPD to be driven actually (m, n≤64) . The column shift register 2, the row shift register 5 and the column latch 3 are all 64 bits; the row number input end 81 and the column number input end 82 of the row number control module 8 are 6-bit inputs; the cascade enable end 16 It is a 4-bit input, and the row cascading signal and ...

Abstract

An adjustable driving circuit of flat panel display component consists of clock generator, line displacement register, line latch, line signal driving circuit, column displacement register, column scan driving circuit. It features that a column ¿C line number control module is added in driving circuit for realizing scale adjustment of it and a cascade enabling end is added on clock generator for realizing cascade.

Description

technical field [0001] A scale-adjustable flat panel display device driving circuit belongs to the field of electronic technology, and in particular relates to a flat panel display device driving circuit. Background technique [0002] Compared with the traditional cathode ray tube (CRT), the flat panel display (FPD) has outstanding advantages such as thin shape, light weight, low voltage drive, low power consumption, no X-ray and flicker. Its applications in portable computers, portable TVs, wall-mounted TVs, computers, household appliances, etc. are eye-catching, and the use of FPDs in information high-speed circuits, HDTV, multimedia, etc. has become a hot topic. [0003] Flat panel displays mainly include liquid crystal display (LCD), light emitting diode display (LED), plasma display (PDP), electroluminescent display (ELD) and field emission display (FED). In particular, liquid crystal displays have the advantages of low operating voltage, low power consumption, large a...
