The TV screen in our home we all know has LCD, OLED screen, etc., LCD is what everyone calls lcd monitor, and the difference between hard screen and soft screen, but also the IPS screen and VA screen we often hear.
First of all, we need to know what is hard screen and soft screen, they do not simply refer to the hardness of the TV screen, but refer to the arrangement of liquid crystal molecules. The hard screen is arranged parallel to the screen, and the soft screen is perpendicular to the screen. The method of differentiation is also very simple, the soft screen will appear water ripples when pressing the screen with the finger, while the hard screen does not, which is also the reason why it is called "hard screen".
The main differences between the two screens are in terms of viewing angle, contrast, color, response time, etc
First, the degree of viewing angle
IPS screen > VA screen
Intuitively speaking, the viewing angle is similar to the effect of watching TV on the side and the front, the IPS screen will hardly lose brightness and color degree no matter which angle, but the VA screen will be reduced at a relatively biased angle to view the picture, and the color and brightness will be reduced in front view. Therefore, if it is the VA screen used by the TV in the home, it is crucial to seize the "C position" in the living room.

Second, contrast
VA screen > IPS screen
As far as the quality of tv pictures is concerned, contrast is one of its important factors, and contrast determines the effect of TV displaying dark pictures, so if the TV contrast is low, when viewing black pictures in a dark environment, the overall appearance will be gray. Therefore, if you want to make the picture contrast better, try to choose a VA screen.

Third, color
IPS screen > VA screen
IPS screens are slightly better in color performance, and the performance of color gamut and color accuracy is better, so it is mainly suitable for professional screens related to image processing.
The color performance of the hard screen is better
Fourth, the response time
IPS screen > VA screen
The IPS screen plays a smoother moving picture, which can show dynamic high-definition pictures without afterimage and tailing. However, at present, the dynamic response time of va soft screen with special customization of high-end TV is relatively fast, so high-end hard-screen TV has no advantages in shadowing compared to high-end soft-screen TV.

Also to talk about the light leakage problem, that is, the user often says "rag screen", IPS screen generally has the problem of light leakage, the screen looks dirty feeling, and the VA screen is basically not the case.
V. How to distinguish between IPS screen and VA screen?
If you still can't tell the difference by pressing the screen by hand, you can also open the mobile phone camera, turn on the flash to take a photo when the TV is off, if the cross pattern is displayed, it is an IPS screen, and if it is displayed as a meter pattern, it is a VA screen.
The word "meter" is a VA soft screen
The word "ten" is an IPS hard screen
6. How to choose between these two screens?
It can be said that more than 70% of the manufacturing cost of a smart TV is used on the screen, so it is best to use the screen when choosing, if there are more family members, often watch TV together, then the IPS screen with a higher viewing angle will be more suitable; if there are fewer family members, while pursuing better screen contrast and better black screen level, then the choice of VA panel is more appropriate, in addition, about the smart TV long-term use performance will become worse and insufficient memory situation, Can be solved by connecting an external TV box, for example, when the shell box this type of product can be.

All in all, it cannot be said which of these two types of screens is better, they have their own advantages and disadvantages, it is best to combine their own use scenarios to choose.
