A liquid crystal display panel and a display driving method are disclosed. The liquid crystal display panel includes data lines, scan lines, common electrode lines, pixel units, voltage buffer circuits and common electrode controller units. The pixel units are coupled to corresponding data lines and scan lines. Each pixel unit includes a storage capacitor. The pixel units on the same row are coupled to the same common electrode line. The common electrode controller units drive the common electrode lines to re-charge each pixel unit via the storage capacitor. The voltage buffer circuits are coupled between the common electrode controller units and the common electrode lines. The voltage buffer circuits are used for maintaining the voltage levels on each of the common electrode lines when each of the pixel units is not in their data writing period.

Liquid crystal display panel and display driving method

A test circuit adapted in a display panel of an electronic device is provided. The test circuit is to test the pixel array function of the display panel, wherein the test circuit comprises: a plurality of test signal lines, a plurality of test signal transmitters, a plurality of gate lines and at least one static electricity protection device. The test signal lines receive a plurality of corresponding test signals respectively. The test signal transmitters comprises a plurality test signal transmitter groups comprising at least one transmitter, wherein each transmitter group corresponds to a test signal line and connects the test signal line and the to pixel array. Each gate line connects to the gate of the at least one transmitter. The static electricity protection device is placed between two of the gate lines.
