Com o rápido desenvolvimento da tecnologia, Telas transparentes de LED atraíram a atenção de todos desde sua estréia, E eles certamente liderarão a próxima nova tendência na indústria de exibição de LED. Contudo, Como escolhemos uma tela de exibição de LED transparente, e através do que podemos entender sua qualidade? Hoje, we will analyze how to choose a transparent LED display screen for you.
Como distinguir entre boas e más telas transparentes LED: Look at the transparency of transparent LED display screens
The transparency of transparent LED displays is related to the dot pitch and process structure. The spacing between points is determined according to the requirements of the project. Quanto maior a distância entre os pontos, the greater the permeability, and vice versa. Determine the process structure based on the technology of transparent LED display manufacturers. This directly leads to product differentiation. It can be said to be a leader in the industry, capable of making various irregular screens and supporting unequal lengths of keels. The horizontal length can reach 2 meters without keels, greatly improving the transparency of transparent LED displays.
Como distinguir entre boas e más telas transparentes LED: Look at the brightness of the LED wall and the viewing angle of the display screen
The brightness of LED lights in indoor environments should be maintained between 800cd/m2-900cd/m2, and in outdoor environments it must be maintained above 1400cd/m2 to ensure the normal playback of displayed images. If you do not meet these standards, you will not be able to see the displayed image because the brightness is too low. The size of the viewing angle refers to the range within which many viewers can see the display, so the larger the better. The size of the viewing angle depends on the packaging method of the chip, so we must consider the viewing angle when packaging the chip. The viewing angle of the transparent LED display screen is 165 °, which can be installed according to the on-site debugging angle, and the brightness can reach up to 4000cd/m2, even under outdoor sunlight, the image is still clear.
Como distinguir entre boas e más telas transparentes LED: issues with blind spots and inlay phenomena
Dead zone phenomenon refers to a single point on the display screen that is always on or constantly black. The reason for the dead point is caused by the quality of the mold. Embedding problem refers to the appearance of small squares or always black on the display, which means module necrosis. The main reason for this phenomenon is the poor quality of the connectors used in the monitor.
How to distinguish the quality of LED transparent screens: the flatness of the display and the presence or absence of color blocks
Due to the direct correlation between the flatness of the display surface and the effect of screen texture and distortion of the displayed image, caution must be taken when adjusting the flatness of the display. Color block refers to the color difference between adjacent modules. The main reason for this phenomenon is due to poor quality of the control system, low grayscale, and low scanning frequency.
