Problems solved by technology

But not every display of picture data needs to be compensated by the backtracking compensation circuit, so the backtracking compensation circuit is in a useless power consumption state most of the time, resulting in unnecessary energy waste, and the power consumption of the display panel is increased, resulting in the work of the display panel. The comparison of efficiency, component life and actual energy loss is not in line with economic benefits, and at the same time increases unnecessary power loss costs

Embodiment Construction

[0016] The preferred embodiments of the present invention are described in detail below with reference to the drawings. see figure 1 An embodiment of the schematic diagram of the system architecture of the present invention is shown. The driving system 1 is applied to a display panel 10 and includes a timing controller 20 and a voltage generator 30 .

[0017] The timing controller 20 is connected to the display panel 10 and transmits the obtained frame data (provided by the system equipment or the image providing device) to the display panel 10 . The source driver 12 converts the frame data into pixel data for writing into the pixel unit 14 . The gate driver 11 is controlled by the timing controller 20 to send out a reference working signal, and the reference working signal will be transmitted to each gate line one by one to open the semiconductor channel of the thin film transistor that controls the charging timing of the pixel unit 14 connected to the gate line Layer, so ...

Abstract

The invention discloses a driving system and a driving method of a display panel. The display panel comprises a plurality of pixel units. The driving system comprises a time sequence controller and a voltage generator, wherein the time sequence controller is used for detecting data values of all pixel units and calculating a difference between the data values of every two pixel units; the calculated pixel units are connected in a column mode, and the positions of front and back columns of the pixel units are adjacent; the time sequence controller can obtain a total value of absolute values ofall differences and judge whether the total value is equal to a critical value to provide an associated control signal for the voltage generator; and the voltage generator can provide a common voltage according to contents of the control signal or provide a compensation voltage for a common electrode.

Description

technical field [0001] The present invention relates to a driving system of a display panel and a driving method thereof, in particular to a driving system of a display panel and a driving method thereof for compensating a common voltage of a common electrode. Background technique [0002] In the prior art, the common electrode (Common electrode) of the display panel is affected by the capacitive coupling (Coupling) of the data line (Source Line), making the common voltage on it unstable, forming a voltage jitter situation, and then generating horizontal crosstalk (Horizontal crosstalk) )Phenomenon. In this way, the manufacturer designs a feedback compensation circuit (Feedback Compensation Circuit) on the display panel to compensate for the common electrode being affected by the data line coupling, so that the common electrode is compensated to reduce the coupling amount, thereby improving the horizontal crosstalk problem. [0003] However, when the display panel is workin...
