Frame compressing method for display panel and frame compressing device

Abstract

The invention provides a frame compressing method for a display panel. The frame compressing method comprises the following steps: acquiring the quantity of the shielded sub-pixels in a display area of the display panel; deleting pixel data in same quantity of the shielded sub-pixels in the display area; integrating the undeleted pixel data and causing the undeleted pixel data and the unshielded sub-pixels in the display area be corresponding to each other; supplying the undeleted pixel data after being integrated to the unshielded sub-pixels in the display area, so that the length-width ratio of the frame displayed by the unshielded sub-pixels in the display area is consistent to the length-width ratio of the frame displayed by all the sub-pixels in the display area. The invention also provides a frame compressing device for the display panel. According to the invention, the purpose of compressing the display frame is achieved, so that the problem of incomplete frame displayed in the display area caused by the display area covered by the external frame of the mechanism is solved.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a picture compression method and a picture compression device of a display panel. Background technique [0002] With the evolution of optoelectronics and semiconductor technology, it also drives the vigorous development of Flat Panel Displays. Among many flat panel displays, Liquid Crystal Displays (LCD) have high space utilization efficiency, low power consumption, Many superior characteristics such as no radiation and low electromagnetic interference have been applied in all aspects of production and life. [0003] During the assembly process of liquid crystal displays, since the area of ​​the display area (Active Area, AA area) of the display panels (that is, liquid crystal panels) produced by each panel manufacturer is different, it is necessary to press the liquid crystal panel and the backlight module The compatibility of the mechanism frame assembled together...

AI Technical Summary

Problems solved by technology

[0003] During the assembly process of liquid crystal displays, since the area of ​​the display area (Active Area, AA area) of the display panels (that is, liquid crystal panels) produced by each panel manufacturer is different, it is necessary to press the liquid crystal panel and the backlight module The compatibility of the mechanism frame assembled together is low

For example, the display area of ​​a display panel produced by a certain manufacturer A is larger than the area area of ​​the display area of ​​a display panel produced by a certain B manufacturer. When pressing and assembling the display panel produced by a manufacturer A, the edge of the display area of ​​the display panel produced by a manufacturer A will be blocked by the outer frame of the mechanism, resulting in the liquid crystal display formed by assembling the display panel produced by a manufacturer A The displayed screen is incomplete
