Embodiment Construction

[0031] The following descriptions of the various embodiments refer to the accompanying drawings to illustrate specific embodiments in which the present invention can be practiced. The directional terms mentioned in the present invention, such as "up", "down", "front", "back", "left", "right", "inside", "outside", "side", etc., are for reference only The orientation of the attached schema. Therefore, the directional terms used are used to illustrate and understand the present invention, but not to limit the present invention. In the figures, structurally similar units are denoted by the same reference numerals.

[0032] Please refer to figure 1 , figure 1 It is a schematic diagram of an existing afterimage improvement method.

[0033] Usually, the solution to afterimage includes purifying liquid crystal molecules, optimizing the optimal common voltage, and shifting the voltage of 0 grayscale, etc.

[0034] like figure 1 As shown, the core idea of ​​the voltage shift of th...

Abstract

The invention discloses an image sticking improving method of a liquid crystal display device and the liquid crystal display device. The liquid crystal display device comprises a display panel, a source electrode drive chip and a compensation module, wherein the source electrode drive chip is used for inputting display frames with preset scanning frequency into pixel units through a data cable; the compensation module is used for inserting compensation frames into the display frames with the preset scanning frequency and inputting the compensation frames into the pixel units, so that the image sticking is eliminated; the compensation frames are generated according to the anomaly difference, and the anomaly difference is the difference between the first positive difference value and the first negative difference value. With the image sticking improving method of the liquid crystal display device and the liquid crystal display device, the image sticking is eliminated, and the display quality is improved.

Description

【Technical field】 [0001] The invention relates to the field of display technology, in particular to a method and a device for improving residual images of a liquid crystal display device. 【Background technique】 [0002] Image sticking is a relatively common phenomenon in poor display of TFT-LCD screens, and it is also a very important test link in reliability testing. Generally, afterimages can be divided into long-term afterimages and short-term afterimages, and the physical mechanisms of their occurrence are also different. The more common one is long-term afterimages. Long-term afterimage is caused by DC residue (DCResidue). [0003] During the manufacturing process of liquid crystals, since the liquid crystal molecules cannot be completely purified, some mobile ions remain in the liquid crystal molecules. When a voltage is applied, these mobile ions will move to a certain electrode under the action of an external electric field, and the polarity of the applied voltage ...
