The utility model relates to the technical field of television sets, in particular to a new type of direct-down backlight module for television sets, which in turn comprises a display screen, an optical diaphragm, a diffusion plate, an LED lamp and a reflective paper from top to bottom. The utility model is characterized in that the middle section of the reflective paper is an inverted trapezoid, and the reflective paper is equipped with a number of LED lamps, and the reflective paper is characterized in that the reflective paper is inverted A pad is arranged between the paper and the diffusion board, and the pad is arranged with a reflective layer near the side of the LED lamp. The oblique edge of the reflective paper is provided with a nylon film and a toughening film, and the nylon film is located below the toughening film. The nylon film and the toughening film enable part of the light to reach the reflective layer of the pad through refraction or reflection, and through reflection. The layer reflects light to the diffuser, and since the thickness of the reflective layer is limited, it only enhances the ambient brightness of the backlight module.
【技术实现步骤摘要】
一种新型电视机直下式背光模组
本技术涉及电视机
,尤其是一种新型电视机直下式背光模组。
技术介绍
在以LED作为背光源的背光模组中,直下式背光模组的LED为矩阵式排布,如此排布方式势必会导致模组中间区域的光线较强,而四周较弱,并在四个角落处叠加,使得电视机显示时,四角出现暗影。长虹等品牌为了解决这个问题采用了具有光线反射功能的垫块,例如四川长虹在中国专利公开的一种直下式背光模组,专利号为201620446655.6。直下式背光模组,从上到下依次包括显示屏、光学膜片、扩散板、背光源、反射纸,其特征在于,在背光模组的四角处,反射纸与扩散板之间设置了具有光线反射功能的垫块。由于LED灯的光线具有一定直射性且反射纸并没有直接朝向垫块的反射端,故其增强四角亮度的效果依然具有改善的空间。
技术实现思路
针对现有技术的不足,本技术提供一种增强背光模组四角亮度的结构。本技术的技术方案为:一种新型电视机直下式背光模组,其特征在于:从上到下依次包括显示屏、光学膜片、扩散板、LED灯、反射纸,其特征在于:所述反射纸中部截面呈倒梯形,所述反射纸上安装有若干LED灯,所述反射纸与扩散板之 ...
