Light distribution of the backlight in the LCD screen
May 03, 2022
LED backlight light conversion technology uses a multi-layer film structure to divide light into P-white light and S-white light, and the S-white light is converted into P-white light after reflection, which can be passed through the LCD.
1、Using LED backlight technology, we can produce a thinner, brighter and clearer display than LCD.
2, LED backlight has a higher refresh rate, is in the video category has better performance performance. D. Lamp reflector
3, LED backlight and LCD LCD power consumption ratio of perhaps 1:10, LED backlight more energy efficient.
For the LCD monitor, the most minor key is its LCD panel and sunlight type, and the LCD panel of the market display monstrosity using TFT panel, is the same, LED backlight and LCD LCD screen difference is only their sunlight type is not the same: LED backlight sunlight and CCFL sunlight (that is, sunlight lamp), the distinction is diode and cold cathode lamp tube. Point light source Lamp (bulb) 2800K inside and outside 1.0 or more 2,000 simple, small, low price, large volume, serious heat LED backlight (shine diode) blue ~ red 430 ~ 700nm 0.038 or more 100,000 life n long, low heat slightly lower brightness line light source CCFL (cold cathode fluorescent tube) red, green, blue and its mixed colors 1.0 ~ 10.0 25,000 High brightness, long life Inverter drive voltage high CCFL (polar cathode fluorescent tube) 4.0~220 5~7,000 Serious heat generation Evacuation plate: to correct the angle of light discontinuance, in order to explore the optical structure of the reflective surface also exists to cover the role of the evacuation plate optical parameters include transmittance and matte degree, depending on the appearance of the light guide plate to make a beneficial choice. Small and medium size commonly used soft material containing silver mass coating and PET, about 79% of the incoming light frequency. Prism sheet: Prism sheet is a secondary component to enhance the frontal luminance, the most effective and commonly used for the BEF series. Simply put, LCD LCD and LED backlight are two different display techniques, LCD LCD is a display composed of liquid crystals, while the LED backlight is a display composed of illumination diodes.
LED backlight is being to the design of the light source, the choice of light source used is very important.
