Analyzing the real situation in the field of display modules can restore the advantages of small pitch displays, thereby expressing the advantages of large pitch displays. If you want to know that there are multiple key elements that are essential under such leadership, it can naturally be said that using a small pitch display screen for device testing can use the resulting methods for testing.
● Test data with small spacing, determined based on the length and height of the display screen (spacing), the length of the joint screen, high brightness, high contrast, etc.
The user characteristics of small pitch displays are determined, allocated, and adjusted based on the size of the display screen.
Some display screens are tested by specialized I-Fi digital oscilloscopes and have strong anti-interference ability. In order to reduce the phenomenon of polarizers on the display screen, they are usually backed up at the maximum brightness and maximum viewing angle of the display screen.
I-Fi switches the signal of the display screen to a digital exchange mode through the Pressure regulator, separates the left and right signals respectively, and confirms whether the timing required for a certain value is met.
I-Fi uses red LEDs to correspond to the positive and negative poles of the U display screen, the positive and negative poles of the red LED display screen, and the negative pole of the green LED display screen.
A small spacing display screen refers to an indoor LED display screen with a spacing of 3mm between the display screen and the building. The white identification signs are mainly composed of red and green LED protocols.
Through the high brightness of the LED screen, the small pitch display screen will not produce color deviation caused by heat, and will decrease the chromaticity.
Strictly prevent leakage at the interface between the screen and the building; The screen should have good drainage measures to ensure smooth drainage in case of accumulated water;
Install lightning protection devices on display screens and buildings. The main body and casing of the display screen should be well grounded, with a grounding resistance of less than 3 ohms, to timely discharge large currents caused by lightning;
Install ventilation equipment to cool down and keep the internal temperature of the screen between -10 ° C and 40 ° C. Install an axial flow fan above the back of the screen to remove heat;
Select industrial grade integrated circuit chips with operating temperatures between -40 ° C and 80 ° C to prevent the display screen from being unable to start due to low temperatures in winter;
To ensure long-distance visibility under strong ambient light, ultra-high brightness LED must be selected;
