Title: DRIVING CIRCUIT OF LIQUID CRYSTAL DISPLAY PANEL AND LIQUID CRYSTAL DISPLAY
Abstract:
Provided are a driving circuit (200, 300, 400, 500) of a liquid crystal display panel and a liquid crystal display. The driving circuit (200, 300, 400, 500) comprises a multi-path distribution circuit (20) and an inversion switching circuit (30, 31, 311, 312). Two input terminals (1', 2') of the inversion switching circuit (30, 31, 311, 312) input two types of data signals with opposite polarities, and output terminals (3', 4') of the inversion switching circuit (30, 31, 311, 312) are connected to input terminals (1, 2) of the multi-path distribution circuit (20), respectively. Output terminals (3, 4, 5, 6, 7, 8) of the multi-path distribution circuit (20) are connected to data cables (S1, S3, S5) of odd columns and data cables (S2, S4, S6) of even columns, respectively. By adding the inversion switching circuit (30, 31, 311, 312) on a data signal input side of the multi-path distribution circuit (20), the connection between two input terminals (1', 2') and two output terminals (3', 4') of the inversion switching circuit (30, 31, 311, 312) are interchanged when a row of sub-pixels (T) is scanned each time, such that polarities of data signals inputted by the multi-path distribution circuit (20) to adjacent data cables (S1, S2, S3, and S4, S5, S6) are opposite, and the polarity of a driving signal outputted by a driving chip is not changed, thereby implementing dot inversion of the display panel and improving the display quality.
