Where does the LED display show better quality! Many LED display manufacturers and enterprises agree that their products are the best. With the continuous improvement of the technical field of LED display screens, the application range of various LED display screens in the current society is becoming wider and wider. LED screens are also divided into occasions, and the requirements for LED display screens in some occasions will be relatively high. We all know the gathering place of LED displays in Shenzhen. However, not all manufacturers in Shenzhen have strong backing strength, so for the quality of LED displays, Lianchengfa will explain the identification of LED displays for everyone here. quality. Many people don't know that heat dissipation issues will directly affect the luminous efficiency of LEDs.

At present, high-quality LED displays solve the heat dissipation problem in terms of design and technology, and can have a life span of more than 30,000 hours, but LED displays with poor design or technology often have a life span of only a few thousand hours or even shorter. From professional research and development, design, production, strict production management, from the selection of components and materials, from advanced automated operation machinery to quality control of the production process, each link is a link. Vital.

　　The following are the steps to identify the quality of the display

　　1. White balance: The white balance effect is the most important indicator of the display screen.

　　2. Flatness: The surface flatness of the LED display is between plus and minus 1mm to ensure that the displayed image is not distorted. Partial protrusions or recesses will cause the viewing angle of the LED display to appear dead. The quality of flatness is mainly determined by the production process.

3. Brightness and angle: the general indoor full-color screen brightness should be above 810cd/m2, and the outdoor full-color screen brightness should be above 1600cd/m2 to ensure the normal operation of the display screen, otherwise it will be difficult to see because the brightness is too low. The displayed image. The brightness is mainly determined by the quality of the LED die. The size of the angle directly determines the audience of the display screen, so the larger the better. The size of the viewing angle is mainly determined by the packaging method of the die. In color science, pure white will be displayed when the ratios of the three primary colors of red, green and blue are 1:4.6:8 respectively. If the actual ratio is slightly different, there will be a deviation of white balance. Generally, pay attention to whether the white is blue or yellow. Green phenomenon. The quality of the white balance is mainly determined by the control system of the display, and the die also has an impact on the color reproduction.

　　4. Color reproducibility: Color reproducibility refers to the color reducibility of the display screen, that is, the color displayed on the display screen must be highly consistent with the color of the playback source, so as to better ensure its real presence.

　　5. Mosaic dead spot phenomenon: Mosaic mostly refers to the small four squares that are always bright or black that appear on the display screen, which is the phenomenon of module necrosis. The main reason is that the quality of the connectors used in the display screen is not up to standard. The quality dead point of an LED display screen refers to a single point that is always bright or black that appears on the display screen. The number of dead points is mainly determined by the quality of the die.

6. Whether there is color block: Color block refers to a relatively obvious color difference ratio between adjacent modules. The color transition is based on the module. The color block phenomenon is mainly caused by the poor control system and the gray level. High, caused by lower scanning frequency.

The above points are related issues described by Lianchengfa for the majority of users. Lianchengfa believes that a good quality LED display must have common sense of these relevant conditions before it can be called a good LED display.
