Shenzhen professional production of light guide screen guide plate Zhongcheng photoelectric

■ main functions: light evenly spread, in order to achieve the effect of shielding the lamp traces. This function depends on the type and proportion with a spreading agent. Diffusion plate is made of PMMA acrylic. ■ Structure and characteristics: the current diffusion plate multilayer structure to achieve the effect of anti-UV, and membership by the formula to improve their water absorption. ■ PMMA-- also called light diffusion plate, a light diffusion plate containing a special light dispersing agent (DF) extruded bead plate (polymethyl methacrylate, PMMA) belongs to the extrusion plate, double-sided frosted, translucent the effect of 85% or more, the internal plate containing light-diffusing particles, so that a uniform distribution of light. Should not be scratched, with the processing, it can adhesion and thermoforming characteristics. ■ diffusion plate characteristics: high transparency - at the same degree of diffusion light transmittance increased by 5% to 15% over conventional diffusion plate, shielding more than 85 percent better - than conventional diffusion plate masking flaws greater cost-effectiveness - due to the factory in Suzhou, low cost and fast delivery of specific competitive advantages good scratch resistance - This board belongs sided Matte, made of light-diffusing particles, with good scratch resistance with good stability and durability ■ Can be used side light LED lighting, such as flat lights, professional film viewer, advertising light boxes, light guide plate with the use of better results. A light diffusion plate widely used in LCD display and LED lighting and imaging system, its main function is to make the scattering of incident light sufficiently to achieve a more gentle, uniform illumination effect. A, applied to the direct type backlight system used in LCD TVs, the diffusion plate having heat resistance, dimensional stability, excellent shielding and durability, making it light diffusion effect to achieve the best and most suitable for direct type backlight unit B, applied to the direct type light source LED lighting system used, it does not need to do a lot of light diffusion, only need to change the visual effects, if the backlight module with micro-structure diffusion plate, a light source will have color shift C, applied to an imaging display system is the direct type light source system used, it is with the lighting of the requirements are the same, but its light transmittance and color shift requires more two, used in LED lighting considerations: 1, the best light mixing performance: 2 soft light and high, high light transmission performance: reduce energy consumption, improve lighting illumination 3, the impact of the light source is small: Keep the light color consistency, reducing color shift 4 minimize optical interference: keep the original lighting design with light curve
