Description
技术领域technical field
本文涉及但不限于显示技术，尤指一种导光板、制备导光板的方法、背光模组及显示器件。This article relates to but not limited to display technology, especially a light guide plate, a method for preparing a light guide plate, a backlight module and a display device.
背景技术Background technique
背光源是位于液晶显示器背后的一种光源，在侧发光式的背光源结构中，一般会在出光侧有亮线产生，亮线产生原因为导光板出光侧边缘的光线经过白色的胶框反射，反射回导光板后与内部的光线产生交叠，导致光线集中，再经过导光板的网点散射到导光板的出光面，即单位面积光线射出量提高，导致局部区域亮度明显加强，给人眼造成视觉上的明亮效果，形成亮线现象，影响画面显示质量。The backlight is a light source located behind the liquid crystal display. In the side-emitting backlight structure, there are generally bright lines on the light-emitting side. The reason for the bright lines is that the light at the edge of the light-emitting side of the light guide plate is reflected by the white plastic frame. , after being reflected back to the light guide plate, it overlaps with the internal light, resulting in concentrated light, and then scatters to the light-emitting surface of the light guide plate through the dots of the light guide plate, that is, the amount of light emitted per unit area increases, resulting in a significant increase in the brightness of the local area, which is eye-catching. It causes a visually bright effect and forms a bright line phenomenon, which affects the display quality of the picture.
在相关技术中，为避免亮线的发生，通常增大遮光胶的尺寸，即增大遮光胶与膜材、导光板的交叠量来遮蔽住亮线的发生区域。当在改善亮线时，由于交叠量增大，往往容易造成以下几个问题：1、无法满足终端的窄边框设计要求；2、减少了终端的有效显示面积；3、导致光能被黑色遮光胶吸收，浪费光能。In the related art, in order to avoid the occurrence of bright lines, the size of the light-shielding glue is usually increased, that is, the overlapping amount of the light-shielding glue, the film material, and the light guide plate is increased to cover the area where the bright lines occur. When improving the bright line, due to the increase in the amount of overlap, it is easy to cause the following problems: 1. Can not meet the narrow frame design requirements of the terminal; 2. Reduce the effective display area of the terminal; 3. Cause the light energy to be blacked out Blackout glue absorbs and wastes light energy.
