Under the goal of pursuing a wide color gamut, global LCD TV manufacturers have introduced LED backlight structures. Of course, this is not a simple matter. In addition to cost considerations, power consumption is an LCD TV to reduce power consumption. era. The research and development of technology to reduce the power consumption of TV backlights has been continuously carried out among the global players.
LCD LED backlight has been expected by the market
LED backlight module is already one of the technologies expected by the market. The high power consumption problem faced by LED backlight has already been solved, because for large-size LCD TV, there is nearly 60% of power. It is consumed on the backlight module, but to reduce the total power consumption is not only a single aspect of LED backlight, but also includes changing the driving circuit technology, enhancing the light guiding efficiency, reducing the thermal effect phenomenon, etc., and also assisting to reduce the total consumption. The technology of electricity.
At present, depending on the application, LED lighting methods are also different. Most LCD TVs use direct-lit backlights, while monitors and small-size applications are mainly side-lit, which is due to both sides. The difference between luminance and color rendering needs. In general, most of the monitors use the RGB3 primary color of the sidelight type. If it is a smaller size application, such as a car navigation panel, a mobile phone panel, a PDA panel, etc., most of them use white LEDs. Side-light mode, but the backlight method of side-light white LED has gradually developed towards large-scale development. At present, some notebook computers have also begun to use backlight modules with side-light white LEDs, so the design of the exterior can be more achieved. The goal of thinning and high elasticity, although the white LED is in the red part, there is a problem of lack of color rendering, but because the notebook computer is mostly used for static display of documents and the like, it is expected to reach the same quality as the LCD TV. After all, not much, so basically the lack of color rendering is not too big a problem, but of course there are ways to overcome, such as adding red LEDs in the array of white LEDs, etc., these methods are also one by one by the backlight module The industry has overcome it.
Leading the neck to expect high efficiency and high brightness LED
However, if the actual popularity of the 3 primary color LED backlights is expected, it is believed that there are still many problems to be solved, and it may take several years. In fact, the fundamental key is to wear the cost, because for LCD TVs, what is needed is high brightness, so it is necessary to use high-efficiency, high-brightness LEDs of 1W or more, plus because it is a direct-lit light, so 3 The number of primary color LEDs used may increase the number of LEDs used due to the increase in panel size. However, this approach brings another problem, that is, the thermal effect will increase due to the increase in the number of LEDs used in the three primary colors. In the first place, more heat sink fins, fans, heat pipes, etc. must be used to maintain the temperature inside the module. In addition, a large number of LEDs are used, and in order to uniform color tone, in addition to strict screening of LEDs with the same wavelength of illumination In addition, Color Sensor must be used to adjust the RGB chromatic aberration, but the effect is increased cost, so it can not effectively make the price meet the expectations of consumers. However, this is not absolute, and other techniques can be used to achieve an increase in panel size without having to use too many 3 primary color LEDs.
However, it is not the backlight module and LCD TV system industry to strive to reduce the power consumption of the LED backlight module. In fact, it also plays a very important role for the LED chip industry, because if the chip industry's efforts can strengthen the LED, If the luminous efficiency is used, then the LED's demand for electricity will be greatly reduced, and the benefits will be directly reflected in the LED backlight module.
