What is Sharp's four-color technology? Please understand the friends who have used it!

Hello, first of all, I feel very sharp. He comes from Japan and started his business on 19 12. Sharp's LCD screen has the leading technology in China and the quality is very good. Moreover, most of Samsung's smartphone screens are produced by Sharp technology. Now I'll give you a detailed introduction of Sharp's "four-color technology"

First, the principle of "four-color technology":

The so-called four-color technology refers to adding a new color-yellow-on the basis of RGB (red, green and blue) of traditional LCD panels. If you compare Sharp's four-color LCD screen with the traditional ASV LCD screen, under the magnifying glass, you will find that the LCD screen with four-color technology has four pixel lattices of red, green, blue and yellow * * *, while on the traditional LCD panel, they all have only three pixel lattices of RGB.

By introducing independent yellow, four-color panel technology allows LCD panels to achieve a wider color gamut. The LCD TV adopting this technology can not only realistically reproduce yellow and gold which are difficult to be reproduced by the traditional RGB tricolor technology, but also enhance the expressive force of blue while enhancing yellow.

Second, the "four-color technology" has expanded the scope of color reproduction.

In the natural world of real life, yellow and cyan are the most common colors, but in the past, these "conventional" colors could not be truly reproduced on TV. The way to improve color saturation is to improve the brightness of backlight and the transmittance of LCD, and improve the color expression of LCD TV at present. "Four-color technology" can obviously improve the performance of yellow color gamut by adding yellow to the sub-pixels of LCD panel, and overcome the deficiency of previous color reproduction ability. At the same time, under the same power condition, the four-color technology realizes brighter white, which is about 20% higher than the three primary colors. Due to the addition of a sub-pixel, the total number of sub-pixels of the whole panel has increased from 6.22 million to 8.29 million. In this way, the picture of "four-color technology" will be more delicate when looking at the same picture image.

Through the "four-color technology", we can more vividly reproduce the colors that are difficult to be expressed by the traditional three-color technology, such as "gold", "shining metallic color" and "bright yellow", stretch the color gamut of blue, improve the expressive force of blue, green and yellow, and more effectively use the yellow wavelength to achieve a wider color gamut and vividly reproduce the colors of the ocean and the sky.

Third, "four-color technology" realizes energy saving and environmental protection.

In order to evolve three colors into four colors, yellow sub-pixels need to be added to pixels of the same size. If the previous liquid crystal technology is used as always, the number of concave-convex structures controlling the direction of liquid crystal molecules will increase, and the light passing through the backlight will decrease, resulting in a decrease in display brightness. In order to improve the brightness, it is necessary to improve the brightness of backlight, which will greatly affect the power consumption. In order to solve this problem, Sharp integrated the previously developed UV2A technology with the four-color technology.

UV2A technology uses ultraviolet light to accurately control the deviation of liquid crystal molecules. The basic principle of photo-alignment UV2A technology is to coat a special alignment film that reacts with ultraviolet rays on the glass substrate. When irradiated by ultraviolet rays, the alignment film will deflect along the irradiation direction, thus driving the liquid crystal molecules to deflect. This technology abandons the original uneven glass substrate, and also improves the light passing through the glass substrate, thus achieving an increase of about 20% in aperture ratio.

Due to the addition of yellow, the brightness is further improved. Combined with Sharp's unique optical alignment UV2A panel technology, it only needs less power consumption to achieve the same brightness level of three-color TV.

In addition, we recommend a "Sharp LCD-46FF 1 LCD TV" produced in February, 20 10, with the latest four-color technology.

The market price is around 13000, and it also supports networks without 3D. FYI
