3)将无边框背光模组9和超窄边框液晶显示模组的半成品组装在一起后通过喷涂胶粘剂21做进一步粘合形成无边框效果。3) After assembling the semi-finished products of the frameless backlight module 9 and the ultra-narrow frame liquid crystal display module, spraying adhesive 21 for further bonding to form a frameless effect.
4)LED灯条组19发出的点光源经过反射片18的反射、导光板16的导光，扩散片15的扩散、上增光片13和下增光片14的增光作用及黑色遮光胶12的固定和遮光作用后，提供均匀的面光源，从而产生“亮边”。4) The point light source emitted by the LED light strip group 19 is reflected by the reflector 18, guided by the light guide plate 16, diffused by the diffuser 15, enhanced by the upper and lower brightness enhancement sheets 13 and 14, and fixed by the black light-shielding glue 12 After the shading effect, a uniform surface light source is provided, resulting in a "bright edge".
本发明专利提出的一种无边框液晶显示模组，该无边框液晶显示模组的半成品是由无边框盖板搭配超窄边框液晶显示玻璃，无边框盖板厚度较厚且边缘存在弧面，此弧面具有折射光线的作用，将超窄边框液晶显示模组的半成品和无边框背光组装在一起后通过喷涂胶粘剂做进一步的粘合，然后通过无边框盖板边缘的弧面折射光线从而达到无边框的显示效果，使液晶显示模组具有更高的用户体现和视觉冲击效果。The invention patent proposes a frameless liquid crystal display module. The semi-finished product of the frameless liquid crystal display module is composed of a frameless cover plate and an ultra-narrow frame liquid crystal display glass. The thickness of the frameless cover plate is thick and there is a curved surface on the edge. This curved surface has the function of refracting light. After assembling the semi-finished products of the ultra-narrow frame LCD module and the borderless backlight, they are further bonded by spraying adhesives, and then refracting light through the curved surface on the edge of the borderless cover to achieve The borderless display effect makes the liquid crystal display module have higher user experience and visual impact.
