Abstract
Description
Technical Field
[0001] The utility model relates to the field of liquid crystal display modules, in particular to a structure for solving the light transmission problem of medium and large-sized LCDs on all sides. Background Art
[0002] In order to meet the high-end quality requirements of customer terminals, the medium and large-sized LCD display module industry has innovated and improved based on the current design foundation and followed this improved design concept, combining considerations such as appearance, product performance, and cost to meet customer requirements and meet the needs of market users. However, in the traditional patch process structure, large-sized display modules will have poor light transmittance due to uneven squeezing force around the glass, which affects the practical experience of the customer terminal and also affects the product quality.
[0003] Based on this, in order to solve the problem of light transmittance around the glass of large-sized display modules affecting the quality, this design proposes a structure to solve the light transmittance of medium and large-sized LCDs around. Utility Model Content
[0004] The utility model aims to provide a structure for solving the light transmission problem of medium and large-sized LCDs.
[0005] A structure for solving the light transmittance problem of medium and large-sized LCDs on all sides, comprising: a CG cover plate, OCA glue, a patch component, a frame foam, and a backlight panel, wherein the CG cover plate structure is a rectangular structure, and the OCA glue is coated on the CG cover plate, wherein the left side of the backlight panel is pasted to the right side of the CG cover plate through the frame foam, the frame foam structure is annular, the patch component is pasted and installed inside the backlight panel, the backlight panel structure is a square frame, the frame foam is pasted on the four sides of the backlight panel, the OCA glue is a full patch design, the OCA glue design size exceeds the edge of the patch component, and the optimal size is the same as the patch component, but in order to ensure the effect and prevent interference, the OCA size is designed to be smaller than the patch component to ensure that there is reserved space for pasting the foam to prevent interference.
[0006] Preferably, the OCA glue has a thickness of 0.2t, and the OCA glue is smaller than the patch component.
[0007] Preferably, a gap of 0.3t is reserved between the CG cover plate and the backlight panel, the thickness of the frame foam is 0.3t, the size of the frame foam is the same as the size of the backlight panel, there is air in the middle of the frame foam, and the thickness of the frame foam depends on the gap reserved between the CG cover plate and the backlight panel, which is generally designed to be 0.5t. After the foam is compressed, the thickness is optimal at 0.3t, which can give full play to the cushioning effect of the foam. At the same time, the outer size of the foam should be the same as the backlight panel. The frame foam can also increase the contact surface between the CG cover plate and the backlight panel, reducing the stress changes in the liquid crystal box due to deformation of the patch component, resulting in poor whitening and light transmittance around.
[0008] Preferably, the patch assembly is composed of glass, FPC and polarizer patch assembly.
[0009] The beneficial effects of the above scheme are:
[0010] This solution achieves a sealed adhesion around the patch component by designing CCA glue and frame foam. At the same time, the design thickness of the frame foam can give full play to the cushioning effect of the foam, reduce the deformation of the patch component, and further ensure that there will be no white light transmission around the LCD display.
