Liquid crystal display module, liquid display device and location method of liquid crystal panel

Abstract

The invention discloses a liquid crystal display module, a liquid display device and a location method of a liquid crystal panel. The liquid crystal display module comprises a rubber frame and the liquid crystal panel, wherein a location structure being used for limiting the liquid crystal panel and corresponding to four sides of the liquid crystal panel is arranged on the rubber frame and comprises movable location members which support against the liquid crystal panel from side surfaces of at least two adjacent sides of the liquid crystal panel and are movably fixed on the rubber frame. Because the location structure used for limiting the liquid crystal panel comprises at least two movably location members which are positioned on adjacent sides of the liquid crystal panel and support against the liquid crystal panel from sides and are finally fixed on the rubber frame, the liquid crystal panel is subjected to position determination and positioned in an assembling process, and can be supported against and regulated through the movable location members during the installation due to a gap caused by size difference, therefore, the invention is capable of adapting to liquid crystal panels with various size differences due to the problem of processing precision.

Description

technical field [0001] The invention relates to the field of liquid crystal display, and more specifically, relates to a liquid crystal display module, a liquid crystal display device and a positioning method for a liquid crystal panel. Background technique [0002] The liquid crystal display module generally includes: a liquid crystal panel, a backlight module and a frame structure, wherein the frame structure includes a plastic frame, and the liquid crystal panel is fixed on the plastic frame. [0003] Such as Figure 1-2 As shown, in the existing module design, the liquid crystal panel 100 is positioned by the positioning blocks 210 arranged near the four corners of the plastic frame 200. In fact, the positioning blocks 210 are arranged near the four corners of the plastic frame , positioning is achieved by defining four sides of the liquid crystal panel 100 . For modules with the same external size, the size of the LCD panel will have some differences in length and widt...

AI Technical Summary

Problems solved by technology

For modules with the same external size, the size of the LCD panel will have some differences in length and width due to processing accuracy, so that such an LCD panel cannot be accurately positioned. For such a problem, it is usually achieved by re-opening the mold to make the plastic frame 200 Its positioning, but doing so not only increases the cost of production, but also reduces production efficiency; another solution is to retain the positioning structure 210 near the four corners, but by adding a difference between the positioning blocks near the four corners and the liquid crystal panel. Thick spacer 400 (such as image 3 and Figure 4 shown), taking the illustration as an example, there are a total of 8 (the material is usually rubber material) to adapt to different sizes of LCD panels. However, for different sizes of LCD panels, the gaps relative to the positioning block are different. It is not only troublesome to assemble, but also needs to increase the man-hours of making spacers, which increases the man-hours of processing and reduces the production efficiency.
