Nowadays, with the continuous development of touch technology, the market share of Android touch all-in-one is also increasing, and the application field is becoming more and more wide. So what is a touch all-in-one? Touch all-in-one computer refers to a touch electronic product that integrates computer, TV, touch screen, LCD screen, audio, multimedia technology, Internet device and other device functions in one. In terms of hardware composition, there are generally LCD screen, touch screen, computer host these three aspects. At present, there are more manufacturers of touch all-in-one machines in the market, so what do we need to pay attention to when we choose the LCD screen for Android touch all-in-one machines? Which LCD screens are clearer, more stable and last longer? Today micro money small make up to talk to you, I hope to help the majority of users.

 
First, LCD screen is divided into soft screen and industrial screen
 
First of all, let's understand, what is soft screen? Soft screen refers to the LCD screen without a protective case, also known as the home screen, its obvious characteristic is that when you poke and press the LCD screen with your finger, the image will appear obvious "water ripple "(will disappear automatically), represented by Samsung, Sharp manufacturers. High definition reflects only in the static condition, the viewing Angle is only 170 degrees, the overall pigment is relatively poor, the color is red, the image and video display will be unstable, there are residual shadow, drag shadow, response speed can only reach 8MS, its characteristics are poor technology, relatively short life, low production cost. So what is an industrial screen? Industrial screen refers to a transparent protective shell with a layer of resin on the liquid crystal panel. It is characterized by the use of a horizontal array of liquid crystal molecular structure, when subjected to external pressure, the molecules of the hard screen recover quickly, when touched, can basically remain unchanged. Color restoration is accurate, response speed is fast.
 
Two, soft screen and industrial screen difference
 
1) Picture quality: the main difference between industrial screen and soft screen is whether there is a transparent protective shell, which has no effect on the picture quality of the two.
 
2) Performance difference: In contrast,IPS hard screen has stronger protection for the screen due to the installation of protective shell, while VA soft screen has stronger heat dissipation performance. It is worth mentioning that, due to the maturity of production technology, soft and hard screen production technology is perfected, such as light leakage (hard screen), color distortion (soft screen) and other problems have been solved.
 
3) Service life: the service life of IPS hard screen is generally about 70,000 hours, and the service life of VA soft screen is about 60,000 hours
 
4) Physical difference: the molecular arrangement structure of IPS hard screen is horizontal, while the molecular arrangement structure of VA soft screen is longitudinal. When confronted with external forces, the molecular structure of the hard screen liquid crystal is much stronger and more stable than that of the soft screen.

 
To sum up, we can see that the industrial screen has a strong performance in the dynamic definition, there is no soft screen LCD screen under external pressure and shaking, the phenomenon of blur and water ripple diffusion, play the speed of the picture to eliminate the shadow and tail. Because most of the applications of touch control all-in-one machine are mainly commercial, which needs a long time to start up and run, thinner thickness, lighter importance and long service life, it can be applied to display equipment 365 days a year without day and night work, which is very practical and can meet the needs of users in different industries.
