    • PURPOSE: A light diffusion plate having an electric wave shield function is provided to remove an electric wave generated from an inverter by stacking a transparent conductive material(7) on a light diffusion plate(3). CONSTITUTION: A reflective plate(1) for reflecting light emitted from a fluorescent lamp(2) downwardly is arranged at the lower portion. A light diffusion plate(3) for enhancing the uniformity of an incident light toward a liquid crystal panel is arranged at an upper surface of the reflective plate(1). The transparent conductive material(7) is stacked on the light diffusion plate(3) for blocking the electric wave generated from the lamp(2) or the inverter. A light diffusion film(5) for spreading uniformly the light and a prism film(6) for making the light progress direction vertical to the liquid crystal panel are arranged sequentially at the upper portion of the light diffusion plate(3).
    • 目的:提供具有电波屏蔽功能的光漫射板,通过在透光板(3)上堆叠透明导电材料(7)来除去由逆变器产生的电波。 构成:用于将从荧光灯(2)发射的光向下反射的反射板(1)布置在下部。 在反射板(1)的上表面配置用于提高朝向液晶面板的入射光的均匀性的光漫射板(3)。 透明导电材料(7)堆叠在光漫射板(3)上,用于阻挡从灯(2)或逆变器产生的电波。 用于使光均匀扩散的光漫射膜(5)和用于使光进入方向垂直于液晶面板的棱镜膜(6)依次布置在光扩散板(3)的上部。

    • PURPOSE: A light diffusion plate of a liquid crystal display device is provided to improve picture quality of a liquid crystal by forming relatively low color coordinates. CONSTITUTION: A light-diffusing agent is included within a transparent resin in order to diffuse the incident light into the transparent resin. A base material layer includes a wavelength transition compound of 1-50 ppm. The wavelength transition compound is used for transiting wavelengths of ultraviolet rays to wavelengths of visible rays. A light diffusion plate includes a base layer(10), a first coating layer(20), and a second coating layer(30). The first and second coating layers are laminated on one side or both sides of the base material layer.
    • 目的:提供液晶显示装置的光漫射板,通过形成较低的色坐标来提高液晶的画质。 构成:透明树脂中包含光扩散剂,以便将入射光扩散到透明树脂中。 基材层包括1-50ppm的波长转变化合物。 波长转变化合物用于将紫外线的波长转移到可见光的波长。 光扩散板包括基底层(10),第一涂层(20)和第二涂层(30)。 第一和第二涂层层叠在基材层的一侧或两侧。
