Abstract

The invention discloses an error compensation device and an error compensation method, and the error compensation device is used for the alignment and fitting of a display panel, and comprises a register, a pattern generator, a sensor, and an address burner. Each pixel in a first substrate and a second substrate is endowed with a coordinate; and the plurality of pixels in the first substrate and the second substrate are lightened to generate the first graphic mark and the second graphic mark, and the position difference between the coordinate position of one point in the first graphic mark andthe position of the corresponding point in the second graphic mark is calculated and compensated, so that the deviation caused by full lamination can be avoided, and the pixel-level brightness control is more accurate.

Description

technical field [0001] The present application relates to the field of bonding of mobile display panels, in particular to an error compensation device and an error compensation method. Background technique [0002] With the continuous improvement of consumers' viewing experience, the requirements for high-dynamic contrast (High-Dynamic Range, HDR) are becoming more and more obvious. As a liquid crystal display (Liquid Crystal Display, LCD), due to the backlight factor, the contrast ratio cannot reach OLED Standard, and the backlight light control can not be fine to the pixel level, in order to make LCD can match the contrast of OLED and the light control effect of pixel level, LCD display has developed a double OC lamination method, using the lower OC to control the brightness of the pixel level, Make LCD products also have dynamic contrast specifications at the same level as OLED products. [0003] In order to accurately control the brightness at the pixel level, the lamin...
