Problems solved by technology

[0004] However, in the existing VCOM voltage compensation technology, the VCOM pull-resistant characteristics are not considered, and it is difficult to controllably adjust the VCOM compensation
Although it can be compensated by using active VCOM voltage input through the timing controller (TCON), etc., the structure of the power integrated circuit (Power IC) is complicated and the cost is high
In addition, in a section where the VCOM voltage difference changes little, the compensation effect is generally poor.

Embodiment Construction

[0045] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the described embodiments, all other embodiments obtained by those skilled in the art without creative efforts also fall within the scope of the present invention.

[0046] Figure 1a A schematic diagram of a display panel 100 according to an embodiment of the present invention is shown. An active display area AA (Active Area) is set in the center of the display panel 100, and a plurality of VCOM capacitors are set correspondingly in the area other than the active display area AA of the display panel, that is, the edge of the fan-out area (Fan Out) of the display panel. ...

Abstract

The embodiments of the invention display a display panel and a manufacturing method thereof, a compensation apparatus, a display apparatus and a common electrode voltage compensation method. The display panel provided by one embodiment of the invention comprises at least one capacitor arranged at an area apart from an effective display area of the display panel so as to enable common electrode voltages of the display panel to maintain stable. The compensation apparatus provided by another embodiment of the invention comprises a compensation module, a comparison module and an adjustment module and can adjust common electrode compensation signals in a controllable mode.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a manufacturing method thereof, a compensation device, a display device and a common electrode (VCOM) voltage compensation method. Background technique [0002] Liquid Crystal Display (LCD for short) has the advantages of low radiation, small size and low power consumption, and is widely used in electronic products such as notebook computers, flat-screen TVs or mobile phones. In a thin film transistor liquid crystal display (TFT-LCD), a gate switching circuit is provided for each pixel, so that each pixel can be controlled relatively independently. Wherein, the common electrode voltage provides a common voltage for the pixel capacitance (Clc) and the storage capacitance (Cs) of each pixel, thereby providing a reference voltage for the substrate of the liquid crystal display. [0003] Pulling of the common electrode (VCOM Shift), that is, the change o...
