Problems solved by technology

[0005] However, the current relatively low-cost gate-on-array (GOA) circuit on the substrate can only generate a single pulse signal, and cannot generate the multi-pulse signal required by the display driving circuit 30. Therefore, the aforementioned display driving circuit 30 It is impossible to use the gate drive circuit on the substrate to replace the gate drive IC (Gate Driver IC) to reduce the cost of the gate drive part
From this point of view, there is still the possibility of reducing the cost of the gate drive circuit

Abstract

The present invention provides a display driving circuit of a flat panel display and a gate control line driving method. The display driving circuit of the flat panel display includes: a data line, a first pixel row, and each pixel includes adjacent first sub-pixels and second sub-pixels. sub-pixels, the first sub-pixel is electrically coupled to the data line to receive the signal provided by the data line, the second sub-pixel is electrically coupled to the first sub-pixel; the second pixel row is adjacent to the first pixel row and every A pixel includes adjacent third sub-pixels and fourth sub-pixels, the third sub-pixel is electrically coupled to the data line to receive a signal provided by the data line, and the fourth sub-pixel is electrically coupled to the third sub-pixel; The first and second gate control lines respectively control the electrical conduction of the first and second sub-pixels and are not used to control the electrical conduction of the third and fourth sub-pixels, so that the gate drive on the substrate ( GOA) circuit becomes possible, reducing the cost.

Description

technical field [0001] The present invention relates to the field of flat-panel displays, and in particular relates to a display driving circuit and a gate control line driving method of the flat-panel display. The drive signal of each gate control line is a single pulse signal. Background technique [0002] Flat panel displays, such as liquid crystal displays, plasma displays, etc., have the advantages of high image quality, small size, light weight, and wide application range, so they are widely used in consumer products such as mobile phones, notebook computers, desktop displays, and televisions. Electronic products have gradually replaced traditional cathode ray tube displays and become the mainstream of displays. [0003] see image 3 , a partial schematic diagram of a display driving circuit 30 of a known flat panel display. The display driving circuit 30 is formed on the substrate 40, including a plurality of pixel rows R1-R4, a plurality of gate control lines G0-G4,...
