Several tips to make LED display screen clearer

LED display screens can be divided into many types, such as: LED unit board, monochrome LED display screen, dual-color LED display screen, inkjet screen, LED full-color display screen, etc. If the display effect of the LED display screen is not clearer, it will directly affect the overall effect of the LED display screen. So how can we make the display of the LED display screen clearer? Let Shenzhen LED display expert Easystar give you some advice.

The grayscale level, contrast, refresh rate and other technical indicators of the LED full-color display directly affect the display effect of the LED full-color display.

1. Grayscale

Grayscale refers to the brightness level that can be distinguished from the darkest to the brightest in the single primary color brightness of the LED display. The higher the grayscale level of the LED display, the richer the color and the more gorgeous the color; on the contrary, the display color is single and the change is simple. The improvement of grayscale can greatly enhance the color depth, making the display level of image color increase geometrically. The LED grayscale control level is 14bit~16bit, which makes the image level resolution details and display effect of high-end display products reach the world's advanced level. With the development of hardware technology, LED grayscale will continue to develop towards higher control accuracy.

2. Improvement of contrast

Contrast is one of the key factors affecting visual effects. Generally speaking, the higher the contrast, the clearer and more eye-catching the image, and the brighter the color. High contrast is very helpful for image clarity, detail expression, and grayscale expression. In some text and video displays with large black-white contrast, high-contrast LED displays have advantages in black-white contrast, clarity, and integrity. Contrast has a greater impact on dynamic video display effects. Since the light and dark transitions in dynamic images are relatively fast, the higher the contrast, the easier it is for the human eye to distinguish such a transition process.

There are two main ways to increase display contrast:

(1) Improve the brightness of LED display

In some situations, the brightness of LED display is not as high as possible. For example, if the brightness of indoor display is too high, it will cause light pollution and damage the eyesight of the observer.

(2) Reduce the reflectivity of the LED display surface

It mainly involves special processing on the LED panel and LED light-emitting tube to reduce the reflectivity of the LED panel, thereby improving the contrast of the LED display.

The NX series of high-end full-color LED displays with a dot pitch of 4mm have been improved from 950:1 in the original process to 4000:1, which has greatly improved the key indicator of the product, namely contrast.
