LCD screen borders are getting narrower 1
Movies often show the effects of future displays, such as transparent displays, holographic displays, and even retinal displays. Although these effects are dazzling enough, they are not realistic from the current technical conditions. LCD Monitors technology cannot develop suddenly and explosively, but can only progress slowly based on existing technology. Therefore, the future displays in movies are not impossible, but it may take a longer time. So what will the more practical changes be like? What are the new features of displays in the next five years? Will you pay for these changes? Let's talk about this today.
The main shortcoming of monitors is the color gamut. The defect of color gamut makes many professionals very frustrated. In the development of LCD Monitors for so many years, there has not been much breakthrough in the change of color gamut. From CCFL backlight to LED backlight, although the volume, energy saving effect and service life of the backlight have improved, in terms of color gamut effect, LED backlight is not much better than CCFL backlight. Even compared with CRT LCD Monitors that have been basically eliminated, today's LCD Monitors cannot easily win.
In fact, improving the color gamut effect is also very necessary for ordinary users. LCD Monitors with a high color gamut have clearer color levels and stronger image rendering capabilities, and perform well in actual applications. Therefore, improving color effects is one of the main breakthrough directions for the development of displays in the next five years.
At present, the color accuracy and color temperature of LCD Monitors have been well optimized, but the color gamut is not ideal. Since backlight is the key to improving the color gamut, improving backlight is a top priority. The more feasible way at present is to use quantum dot technology. Quantum dots are extremely small semiconductor crystals, about 3 nanometers to 12 nanometers in size. Quantum dots of the same size can emit different light under the stimulation of blue LEDs. The larger the size, the more the light emitted by the quantum dots is biased towards the purple area in the spectrum, and vice versa.
This kind of quantum dot can be made into a thin film structure, which can emit light with higher purity under the current blue LED light stimulation. Such a backlight system will have better color gamut performance, because the original LED backlight is formed by blue LED mixed with yellow phosphor, and such white light spectrum components are not conducive to the improvement of color gamut. Quantum dot backlight has RGB three colors, which is a more advantageous white light.
At present, the development speed of quantum dot technology is very fast, and the cost reduction speed is also sharp. In the next five years, quantum dot technology will greatly improve the color gamut effect of the LCD Monitors . For this change, as an ordinary consumer, will you pay for it?
