Special Size and Shape Custom Backlight

LCD is a non-luminous display device, which requires the use of a backlight to achieve the display function.  The performance of the backlight source will directly affect the display quality of the LCD. The cost of the backlight source accounts for 3-5% of the LCD module, and the power consumed accounts for 75% of the module. It can be said to be a very important part of the LCD module.  Components.  High-definition, large-size LCDs must be matched with high-performance backlight technology. Therefore, as the LCD industry strives to open up new application areas, the high-performance backlight technology (such as high brightness, low cost, low power consumption)  It also plays the role of hero behind the scenes.The light source is mainly composed of light source, light guide plate, optical diaphragm, plastic frame, etc.  The backlight has the characteristics of high brightness, long life and uniform light emission.  The service life of LED backlight is longer than EL (more than 5000 hours), and it uses DC voltage. It is usually used in small monochrome displays, such as telephones, remote controls, microwave ovens, air conditioners, instrumentation, stereo audio equipment, etc.  However, its brightness is currently not enough to provide a back light source for large transmissive displays.  The function of the backlight module is nothing more than to make the light emitted by the point light source or the line light source become a surface light source through diffuse reflection.  However, this backlight is very knowledgeable, and its surface texture will change differently when matched with different numbers of lamps. The design of the backlight includes optical design, precision molds, and precision technology such as etching and printing.The so-called LED refers to Light Emitting Diode, which is what we often call light-emitting diodes. In layman's terms, it is the carriers injected into the PN junction. After the minority carriers are combined with the majority carriers, they release energy. Expressed in the form of light to achieve electroluminescence. This kind of product and its application are not only available now, and its application can be seen everywhere in our real life, such as roadside billboards, various indicator lights on household appliances and backlighting on mobile phone keyboards, etc. LED is used as the light source, so when talking about LED, we should not feel new, so there is no need to explain this product and its working principle in detail here, but it is used in display products. Said, it should also be regarded as an emerging technology product.In addition, the advantage of LED as a backlight source is that it can replace the use of color filters. The three-color RGB LED adopts color sequential technology to use the characteristics of human vision to achieve full-color effect, so it can replace color filters. Of course, this must be achieved with the response speed of the liquid crystal. But to reach this state, there are still many difficulties that must be overcome. The remarkable features of LED are high photoelectric conversion rate, high color saturation, small size, vibration resistance, no toxic substances, low voltage power supply, safety to the human body, and long life.   The LCD screen itself does not emit light and needs a backlight. The LED backlight LCD TV uses LED light-emitting diodes as the backlight, which has five advantages over cold cathode fluorescent tube backlights:1. Ultra-wide color gamut, which can reach 105% NTSE color gamut, so colors are more vivid. 2. Ultra-thin appearance, the thinnest reaches 1.99 cm, more fashionable.3. Energy saving and environmental protection, energy consumption is 52% lower than cold cathode backlight, and there is no mercury pollution of cold cathode tube.4. Long lifespan, reaching nearly 100,000 hours. It can be used for 27 years if it is opened for 10 hours a day.5. Ultra-high contrast ratio of 10000:1 can be achieved, and the definition is higher.LED baklight characters:1. Color: white, warm white, RGB, amber, green, yellow, blue, etc.2.
