Embodiment Construction

[0059] Some terms are used in the description and claims to refer to specific components. However, those with ordinary knowledge in the technical field of the present invention should understand that manufacturers may use different terms to refer to the same component. Moreover, this specification And the claims do not use the difference in name as the way to distinguish components, but the difference in the overall technology of the components as the criterion for distinguishing. "Includes" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". Furthermore, the term "coupled" herein includes any direct and indirect means of connection. Therefore, if it is described that a first device is coupled to a second device, it means that the first device may be directly connected to the second device, or may be indirectly connected to the second device through other devices or other connection means.

Abstract

The invention provides a panel driving circuit, which includes a gate driving circuit, at least one connection circuit and a control circuit. The gate driving circuit is coupled to a plurality of gatelines and generates a plurality of gate signals to the gate lines. The connecting circuit connects an Mth gate line and a Pth gate line of the gate lines, where M and P are positive integers. The control circuit is coupled to the connection circuit and controls the connection circuit. The gate driving circuit outputs the gate signals to the Mth gate line, and during the scanning of the Mth gate line, the control circuit controls the connection circuit to tunr on a connection path between the Mth gate line and the Pth gate line.

Description

technical field [0001] The invention relates to a driving circuit, in particular to a panel driving circuit with power-saving design. Background technique [0002] The thin film transistor liquid crystal display includes a display panel and a driving circuit. The driving circuit controls the output voltage of the pixel transistors of the display panel to control the alignment direction of the liquid crystals in the display panel, and then controls the light transmittance to produce grayscale color effects. The driving circuit is electrically connected to the gate terminals of the pixel transistors, and is responsible for switching each row of pixel transistors, and turns on a whole row of pixel transistors at a time during scanning. When the pixel transistor is turned on (ON), the driving circuit transmits the voltage for controlling brightness and gray scale to the pixel of the display panel through the channel formed by the source terminal and the drain terminal of the pix...
