The screen on some mobile phones almost occupies half of the cost of the mobile phone. For example, the recently popular curved screen mobile phone is accidentally broken, and you say it hurts. The quality of the screen also indirectly reflects the consumer's aesthetic and purchasing desire.
Mobile phone screen, mainly look at two parameters, the first is the resolution of the screen, the second is the material of the screen.
The resolution can be understood by everyone, that is, the bigger the value, the clearer it is. It is no longer the era of cell phone particle explosion, but the higher the resolution, the more electricity it will consume. At present, the market is at least 720P resolution, the standard is 1080p, and the high end is 2K or 4K resolution.
The material of the screen is divided into LCD and LED. The former is represented by Apple's IPS screen, and the latter is represented by Samsung's AMOLED.
The advantages of the IPS screen are: soft and natural color, wide viewing angle, and no discoloration when viewed from any angle. The disadvantages are: light leakage, poor contrast.
The advantages of the AMOLED screen are: bright colors, lighter and lighter than IPS. The disadvantage is: because the penTIle arrangement causes the screen to be viewed from different angles, the color will be different. This is the origin of the blue-green screen of the partial color screen. The solution is to increase the PPI, so the screen of the 5.5-inch screen and above is very good. necessary.
IPS manufacturers are very common, such as high-end Sharp, Sony, LG, etc., low-end Tianma. The 2k L-screen is basically Sharp's product.
There are very few AMOLED manufacturers. 95% of AMOLEDs in the world are produced by Samsung. The remaining share is mostly LG, and the only manufacturers that can produce 2k resolution AMOLED screens on a large scale are Samsung.
