The quality of the screen of an industrial tablet directly affects the user experience, so careful testing is necessary before purchasing. Here are some suggestions to test the screen quality of industrial tablets:

1. Resolution: Check if the screen resolution of the industrial tablet meets the requirements. A high-resolution screen can provide clearer images and richer details.

2. Color accuracy: Use professional color testing tools to test the color accuracy of the screen. The higher the color accuracy, the more accurate the colors displayed on the screen.

3. Contrast: Contrast refers to the difference in brightness between the brightest and darkest areas on the screen. A higher contrast can provide better visual effects and make the image clearer.

4. Brightness and viewing angle: Test the brightness and viewing angle of the screen to ensure that there is no significant change in color and contrast when viewed from different angles.

5. Response time: Response time refers to the time required for the image on the screen to switch from one state to another. A shorter response time can reduce motion blur on the screen and provide a smoother picture.

6. Touch sensitivity: Test the touch sensitivity of industrial tablets to ensure rapid and accurate screen response.

7. Screen saver: Check if the screen has anti glare, anti scratch and other protective functions to extend the screen's lifespan.

8. Power consumption and heat dissipation: Test the power consumption and heat dissipation of the screen under normal usage conditions to ensure that prolonged use will not cause overheating.
