Abstract

The invention provides a display panel. The display panel comprises a first gate line driving circuit and a second gate line driving circuit, which are respectively arranged on two sides of a display area, and controls the same pixel in the display area via a first gate line and a second gate line. The first gate line driving circuit is electrically coupled to the first gate line so as to provide a first control signal to the first gate line. The second gate line driving circuit is electrically coupled to the second gate line so as to provide a second control signal to the second gate line. In addition, the second gate line driving circuit is electrically coupled to a luminance control line so as to provide a luminance control signal to the luminance control line and control the same pixel to emit light at any time via the luminance control line. According to the invention, a gate control signal generator is divided into two areas, so uniformity of luminance of the display panel is better, and poor display effects caused by influences on normal operation of circuits due to errors in manufacturing technique are avoided.

Description

technical field

[0001] The present invention relates to a display panel, in particular to a driving circuit of the display panel. Background technique

[0002] A flat-panel display is a display device that displays images based on pixel circuits, and different pixel circuits may require different driver circuit designs to make the images display normally.

[0003] Please refer to figure 1 , which is a common circuit diagram of a pixel circuit in a flat panel display. The pixel circuit 10 controls P-type transistors T1, T2, T3, T4, T5 and T6 and two capacitors C through two gate control signals Scan_N and Scan_N-1 and one light emission control signal EM. st1 with C st2 , so as to determine when to receive the display data DATA and when to control the light emitting diode D1 to emit light under the supply of the illuminant driving working potentials OVDD, VIN and OVSS. For example, figure 1 The circuit diagram shows that the control terminal of the first transistor is on...
