Problems solved by technology
However, when the touch panel in the LCD is bonded to the LCD panel, the light from the backlight module may pass through the edge of the touch panel and enter the visible area, resulting in edge failure when the user observes the screen at a large viewing angle. The problem of light leakage makes users feel bad

Embodiment Construction
[0016] figure 1 with figure 2 A liquid crystal display 1 capable of preventing light leakage according to the present invention is schematically shown. The liquid crystal display 1 capable of preventing light leakage includes a touch module 10 , a display module 20 and a backlight module 30 , wherein the display module 20 is arranged between the touch module 10 and the backlight module 30 between. A first adhesive member 40 is disposed between the touch module 10 and the display module 20 for bonding the touch module 10 and the display module 20 .
[0017] The first adhesive member 40 includes an adhesive layer 41 and a light-shielding layer 42 made of opaque material disposed above the adhesive layer 41 . In this embodiment, the adhesive layer 41 is roughly rectangular in shape and provided with square openings. Please also refer to figure 2 The light blocking layer 42 includes a horizontal portion 421 attached to the adhesive layer 41 and a vertical portion 422 vertic...

The invention provides a liquid crystal display capable of preventing light leak and a method for assembling the liquid crystal display. The liquid crystal display comprises a touch control module, a backlight module and a display module arranged between the touch control module and the backlight module, wherein a first bonding piece is arranged between the touch control module and the display module, and comprises a bonding layer and a light blocking layer arranged above the bonding layer; the light blocking layer comprises a horizontal part bonded with the bonding layer and perpendicular parts perpendicularly stretching out of the horizontal part; the horizontal part and the first bonding layer are bonded between the touch control module and the display module; and the perpendicular parts are bonded with the side edges of the touch control module. According to the liquid crystal display and the method, the light blocking layer is attached on the side edge of the touch control module, so that light rays emitted by the backlight module can be prevented from leaking from the side edge of the touch control module after passing through the display module.
Description
technical field [0001] The invention relates to liquid crystal display technology, in particular to a liquid crystal display capable of preventing light leakage and a method for assembling the liquid crystal display capable of preventing light leakage. Background technique [0002] Liquid crystal displays are currently the most commonly used flat panel displays. Since the liquid crystal itself has no light-emitting properties, the backlight module is one of the key components of the liquid crystal display. Its function is to supply evenly distributed light sources so that the liquid crystal display can display images. However, when the touch panel in the LCD is bonded to the LCD panel, the light from the backlight module may pass through the edge of the touch panel and enter the visible area, which will cause edge failure when the user observes the screen at a large viewing angle. The problem of light leakage makes the user experience poor. Contents of the invention [0...
