In this article.
技术领域Technical field
本发明涉及液晶显示技术领域，特别涉及一种液晶面板与背光模组定位胶结构及显示器。The present invention relates to the field of liquid crystal display technology, and in particular, to a liquid crystal panel and a backlight module positioning adhesive structure and a display.
背景技术Background technique
目前，液晶显示装置作为电子设备的显示部件已经广泛的应用于各种电子产品中，随着电子产品轻薄化的发展，电子设备的边框被设计得越来越窄。而背光模组则是液晶显示装置中的一个重要部件，背光模组的边框也势必要越来越窄。At present, a liquid crystal display device has been widely used as a display component of an electronic device in various electronic products. As the electronic product is light and thin, the frame of the electronic device is designed to be narrower and narrower. The backlight module is an important component in the liquid crystal display device, and the frame of the backlight module is also required to be narrower and narrower.
现有技术中的背光模组均包括胶框，导光板被胶框包围，光学膜片通过定位遮光油漆带固定于所述导光板和胶框上。液晶面板定位在背光单元的定位遮光双面胶带上，黑色双面胶的宽度刚好位于人眼看不到的位置，即光线射出位置随着液晶模组的边框宽度越来越窄，所述定位遮光油漆带的宽度也越来越窄，导致定位遮光油漆带与光学膜之间的定位强度减弱，容易发生膜片定位不可靠。为了保证膜片的定位可靠度，定位遮光油漆带的宽度不能无限度的缩窄，因此人眼可以透过液晶面板看到背光单元的黑色边缘，这样影响了整个液晶面板的透光品质。The backlight modules of the prior art each include a plastic frame, and the light guide plate is surrounded by the plastic frame, and the optical film is fixed on the light guide plate and the plastic frame by positioning the light-shielding paint strip. The liquid crystal panel is positioned on the positioning light-shielding double-sided tape of the backlight unit, and the width of the black double-sided tape is just located at a position that is invisible to the human eye, that is, the position of the light emission is narrower as the width of the frame of the liquid crystal module becomes narrower, and the positioning is blocked. The width of the paint strip is also narrower and narrower, resulting in a weaker positioning strength between the positioning shading paint strip and the optical film, and the diaphragm positioning is unreliable. In order to ensure the reliability of the positioning of the diaphragm, the width of the positioning shading paint strip cannot be narrowed indefinitely, so that the human eye can see the black edge of the backlight unit through the liquid crystal panel, which affects the light transmission quality of the entire liquid crystal panel.
