What Is The Size Of The Display Screen Of The Self-service Terminal?

With the rapid development of high-tech, self-service terminal manufacturers have integrated various technologies such as infrared touch technology, online office learning software, multimedia system communication network technology, ultra-clear flat panel display technology, etc. , interactive whiteboard, computer, TV, touch screen and other multi-purpose interactive teaching equipment in the self-service machine, which has upgraded the traditional display equipment into a fully functional human-computer interaction technology machine and equipment. What is the size of the display screen of the teaching machine? Generally, there is no appropriate answer to this problem. We can consider the following factors to choose a suitable display size of the self-service machine.

1. Spacing

The same item is placed on the other end of the dining table, and the difference between a 60-centimeter-deep dining table and a one-meter-deep dining table is 40 centimeters. If it is a pull-out computer keyboard frame, it is generally 20 cm farther than the desktop computer keyboard.

2. The aspect ratio of the display

Common screen sizes are 4:3, 5:4, 16:10, 16:9, 21:9. The same overall width of the display, 4:3 and 21:9 specifications are obviously different.

3. Angle

Although 60 degrees is a comfortable angle of view for human eyes, in fact, not all people's comfortable angles are the same. In addition, 60 degrees is a comfortable angle for one eye, and there is a problem of overlapping eyes.

4. Sitting posture

Leaning forward and leaning back on the table and chair can be 30 cm apart. Therefore, the closest application distance and the farthest application distance can be separated by 90 cm. If the closest application distance is 30 cm, and the farthest application distance is 120 cm, if the same is measured according to the eye comfort angle of 60 degrees, the total width of the previous display screen is 30tan (60/2) 2=34.64CM, the latter one is 120tan(60/2)2=138.56CM.

5. Indicate the content

If the content of the display requires you to care about the content displayed on the side/bottom left/bottom right as far as possible, then it is recommended to place all the displays within your comfortable angle. Conversely, if you only care about the center area, then just make sure the center area is within a comfortable angle.
