  • the LCD display used is a layered structure composed of different parts.
  • the LCD consists of two glass plates with a thickness of about 1 mm, separated by a uniform interval of 5 ⁇ m containing a liquid crystal material. Because the liquid crystal material itself does not emit light, there are lamps on both sides of the display screen as a light source, and on the back of the liquid crystal display screen there is a backlight plate (or uniform light plate) and a reflective film.
  • the backlight plate is composed of fluorescent substances Can emit light, its role is mainly to provide a uniform background light source.
  • Liquid crystal display technology also has weaknesses and technical bottlenecks. Compared with CRT (Cathode RayTube) displays, there are obvious gaps in brightness, picture uniformity, viewing angle and response time. The response time and viewing angle depend on the quality of the display panel, and the uniformity of the picture has a great relationship with the auxiliary optical circuit.

It reflects the speed at which each pixel of the liquid crystal display responds to the input signal. Speed from dark to light or from light to dark. The smaller the response time is, the user will not feel the drag of the tail when watching the motion picture.

Description

一种发光部件及显示装置
本申请要求于2018年06月26日提交中国专利局、申请号为CN2018209875464、发明名称为“一种发光部件及显示装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及显示技术领域，尤其涉及一种发光部件及显示装置。
背景技术
这里的陈述仅提供与本申请有关的背景信息，而不必然地构成现有技术。
LCD(Liquid Crystal Display的简称)液晶显示器。
LCD的构造是在两片平行的第二基板当中放置液晶盒，下基板玻璃上设置TFT(薄膜晶体管)，上基板玻璃上设置彩色滤光片，通过TFT上的信号与电压改变来控制液晶分子的转动方向，从而达到控制每个像素点偏振光出射与否而达到显示目的。
从液晶显示器的结构来看，无论是笔记本电脑还是桌面***，采用的LCD显示屏都是由不同部分组成的分层结构。LCD由两块玻璃板构成，厚约1mm，其间由包含有液晶材料的5μm均匀间隔隔开。因为液晶材料本身并不发光，所以在显示屏两边都设有作为光源的灯管，而在液晶显示屏背面有一块背光板(或称匀光板)和反光膜，背光板是由荧光物质组成的可以发射光线，其作用主要是提供均匀的背景光源。
液晶显示技术也存在弱点和技术瓶颈，与CRT(Cathode Ray Tube)显示器相比亮度、画面均匀度、可视角度和反应时间上都存在明显的差距。其中反应时间 和可视角度均取决于显示面板的质量，画面均匀度和辅助光学电路有很大关系。
对于液晶显示器来说，亮度往往和他的背板光源有关。背板光源越亮，整个液晶显示器的亮度也会随之提高。信号反应时间也就是液晶显示器的液晶芯片响应延迟。实际上就是指的液晶芯片从一种分子排列状态转变成另外一种分子排列状态所用的时间，响应时间愈小愈好，它反应了液晶显示器各像素点对输入信号反应的速度，即屏幕由暗转亮或由亮转暗的速度。响应时间越小则使用者在看运动画面时不会出现尾影拖拽的感觉。
LED发光部件由于其色彩还原性好、亮度高、省电、易于进行分区控制等优点，将成为液晶显示屏的主流背光源。LED发光部件根据LED所处的位置的不同，又可以分为侧光式LED发光部件和直下式LED发光部件。直下式LED发光部件工艺简单，不使用导电板，LED阵列置于灯箱底部；直下式LED发光部件为了保证光均匀，因此其厚度通常比较厚。侧光式LED发光部件将点状光源设置在经过特殊设计的导光板侧边光作为背光源，使用LED颗数较少，因LED置于产品的侧面，因此只添加导光板就可以保证光均匀性，因此其厚度相较于直下式LED发光部件厚度较薄。
然而，直下式LED发光部件任然是通过LED和导光板这种两种结构组成作为背光源，LED和背光源的厚度使得在发光部件轻薄化的发展当中任然存在瓶颈。
