Liquid crystal display (LCD) a type of display used in digital clocks and many portable computers. The LCD display uses two pieces of polarizing material, between which is a liquid crystal solution. The current flowing through the liquid rearranges the crystals so that light cannot pass through them. Therefore, each crystal is like a shutter, which can allow light to pass through and block light.

Liquid crystal display (LCD) is developing towards the goal of light, thin, short and small. Of course, the display products with a long history around the computer are no exception. Under the premise of being easy to carry and carry, the traditional display methods, such as CRT image tube display and LED display board, are constrained by factors such as large volume or huge power consumption, which can not meet the actual needs of users. The development of LCD technology is just in line with the current trend of information products, whether it is right angle display, low power consumption, small size, or zero radiation and other advantages, can let users enjoy the best visual environment.

Since Apple introduced the concept of retina screen, it has been gradually applied to tablet. Retina screen with high resolution and high pixel density is very good in terms of image quality, such as bright color of image quality and strong sense of delicacy. The following figure shows two 9.7-inch flat plates. On the premise that the brightness of the two plates are the same, the image display effect of the obvious retina is bright and sharp due to the ordinary screen, and the brightness is also high.

When playing different pictures, the display effect of the same retinal display screen is still obvious. Due to the high pixel density of the retina screen, we can see the grainy feeling on the ordinary screen after enlarging the same size image by the same multiple, but the retina screen still remains the same. Then play the video, and the comparison is more obvious from the figure below. With the same video playing, the visual effect of the retina screen is better, no matter from the brightness of the color or the overall picture performance, the advantages are outstanding.

In the case of acceptable price, the image effect of retina screen is far better than that of ordinary screen, especially for some users who require high image quality. However, for the users with high requirements of image quality and expressiveness, the daily use of ordinary screen is still no problem.

Retina screen is a new technology screen, which is different from the previous LCD screen. It uses the principle of retinal visual residue in the human body, so as to achieve the purpose of imaging. Compared with the previous screen, the pixels of this new retina screen are greatly increased, and the size of the screen is also smaller and smaller, but this technology is not mature, It has just been developed and put on the market. At the same time, the development of this technology has encountered a bottleneck. If we want to continue to develop, we may need a lot of financial support. Therefore, it is unclear whether there will be more new technology to replace this kind of screen.

Due to the high pixel density of the retina screen, the same size of the image can be magnified by the same multiple, the ordinary screen can already see the sense of particles, but the retina screen still remains the same. With the same video playing, the visual effect of the retina screen is better, no matter from the brightness of the color or the overall picture performance, the advantages are outstanding.
