How to choose segment code LCD screen

Time：2023-09-28

1. Choose the suitable viewing angle range of the display screen

Segment code screen viewing angle range is one of the very important indicators, it will directly affect the later user interaction experience. General TN screen is the smallest range of vision, about 50°, and HTN about 70° or so; VA segment code LCD screen on the middle of the road, in about 100°. Almost equal to the full viewing angle are FSTN and STN screens, with a viewing range of more than 150° or more. At this time, how to go about choosing?

In fact, it depends on the use of your product scene, if you really need a wide viewing angle, then choose STN and FSTN. if the viewing angle is wider, the screen needs to be made into a color silkscreen, then choose the VA material segment code LCD screen. If all the requirements are not high, you can choose TN or HTN material segment code LCD screen.

2. Choose the appropriate brightness of the LCD screen

If the segment code LCD screen is semi-transparent or fully transparent type, then you need to install the backlight. Therefore, the suitable segment code LCD screen brightness is also very important. A good backlight brightness can reach between 200cd/m2 and 3000cd/m2. This still depends on the needs of your own product. Generally the brightness is determined by the power supply voltage we provide to supply the LCD screen and the brightness of the backlight, when customizing this, you can ask the manufacturer of the segment code LCD screen about your requirements.

3. Choose the best contrast ratio segment code LCD screen

In a good screen, the contrast ratio is also particularly important. A segment code LCD screen with a high contrast ratio will give a good view and not look eye-catching. With a high contrast ratio, the color and fineness of the pattern will be greatly improved and layered. On the contrary, the segment code LCD screen will give people an opaque feeling.

Segment code LCD screen contrast also has a lot to do with the material of the screen. the contrast of VA segment code LCD screen is the highest in these models, followed by TN, HTN front display, STN, FSTN and other contrast performance is also very good.
