Refresh rate The number of times the content of the LED display can be repeatedly displayed per second is called the refresh rate. When the refresh rate is low, the displayed image will flicker, especially when the flicker is too obvious during the video shooting, so it must be maximized Increase the refresh rate to ensure the stability of the display.

Image Acquisition The LED display of the image uses an electronic light-emitting system to display the result of image conversion of the digital signal. The special video card JMC-LED came into being, and formed a unified compatibility with VGA and video functions on the basis of the PCI bus using a 64-bit graphics accelerator, so that the video data was superimposed with the VGA data, and the lack of compatibility was improved. Using the full-screen method to capture the resolution, the video image can achieve full-angle resolution and enhance the resolution effect, eliminate edge blur, and can zoom and move the image at any time, and can respond to different playback requirements in time. Effectively separate the red, green and blue colors to enhance the true color imaging effect of the electronic display

ISP in logic circuit design With the emergence of System Programmable Technology (ISP), users can repeatedly repair the deficiencies in the design and design their own goals, systems or circuit boards, and realize the designer application functions of software integration. At this time, digital systems and system programmable technologies The combination brings new application effects. The introduction and use of new technologies effectively shortens the design time, expands the limited use of components, simplifies on-site maintenance, and facilitates the realization of target equipment functions. When the system software is inputting logic, the influence of the selected device can be ignored, and input components can be selected at will, or virtual components can be selected to perform adaptation after input is completed.

Contrast The contrast of the display screen affects the visual imaging effect. High contrast improves the clarity of the picture and the bright colors, and effectively improves the image quality of the details, clarity, and gray level. In addition, contrast also has a certain impact on the resolution and conversion of dynamic video. High contrast makes it easier for the naked eye to distinguish the light-dark conversion process in dynamic images.

Gray scale The gray level of the LED display screen is mainly used to evaluate its color reality. By judging the brightness level from the darkest single primary color to the brightest, the gray level is used as the standard to evaluate the display color. When the gray level is high, the display is rich and gorgeous; when the gray level is low, the color change is single. Therefore, the improvement of the gray level is beneficial to increase the color display level of the image and contribute to the improvement of the color depth.

Color, brightness and viewing angle With the combination of diode system and semiconductor, its production materials and manufacturing processes are gradually upgraded, breaking through the original brightness and color limitations, and a large number of blue diodes and pure green light-emitting diodes are used to enhance the brightness of the display. Furthermore, the advantages of LED display screens in outdoor environments are improved, which can adapt to different display requirements and enhance the effective value of LEDs in different environments. The evaluation of LED display performance must be the result of comprehensive consideration, because its related performance indicators are closely related, and indicators such as brightness, viewing angle, and resolution affect each other. At present, surface mount LED devices are used in high-density, full-color indoor displays to improve the viewing angle and brightness performance of the display.

The display mode is colorful and the display works offline. LED display has wide application in various industries because of its flexible control, convenient operation and low cost.

What is the difference between LED display (3 in 1) and LED display (3 in 1)? The following small series for you to sort out the eight major differences for the reference of the industry. 1. The LED display screen 3 in 1 full screen angle of view is larger than the LED display 3 spell 1 , and the 3 in 1 surface can be used for light diffuse reflection processing, and the effect obtained is no granularity compared with the LED display 3 spell 1 . Good coloring. 2. In terms of color, the LED display 3 in 1 full color splitting color separation is easier than the LED display 3, and the color saturation is high. 3. LED display 3 in 1 is to use the entire surface to emit light, and LED display 3 spell 1 is limited to point lighting, so the overall color of the LED display 3 in 1 is evener than the LED display 3. 4, LED display 3 in 1 from the overall flatness is better than the LED display 3 spell 1. 5. LED display 3 spell 1 compared with LED display 3 in 1 maintenance cost is low, the implementation of single lamp maintenance, maintenance is simple. 6. LED display 3 spell 1 is 3 points separate power supply, low power consumption, fast heat dissipation, effectively extend the life of the screen, high reliability. 7. LED display 3 spell 1 IC, drive chip temperature is lower than LED display 3 in 1 to improve the overall life of the screen 8. Use the same point spacing, the same constant current static, the same in the whole screen In the case of a light-emitting chip and the same chip, the cost of the LED display screen 3 is one more favorable than the LED display screen. Why LED display (3 spell 1) is more expensive than LED display (3 in 1), because LED display (3 spell 1) is composed of red, green and blue three lights, so high-speed placement machine 3 times to complete a point, and the LED display (3 in 1) high-speed placement machine can complete a point once, in the production process, the three-in-one production efficiency is high, so the display is better than 3 It is cheaper.

The LED display is composed of LED dot matrix and LEDPC panel. The red, blue, white and green LED lights are displayed to display text, pictures, animations and videos. The content can be changed at any time, and all components are modular. Structured display device. Traditional LED displays typically consist of a display module, a control system, and a power system. The display module is composed of a dot matrix composed of LED lights, and is responsible for the light-emitting display; the control system can display the text, the picture, the video and the like by controlling the corresponding area to be turned off, and the monochrome and the two-color screen are mainly used for playing the text. The color LED display can not only play text, pictures, animations, but also video and other formats. At present, it has been widely used in every corner of the world with its wide audience, simple operation, long service life and energy saving and environmental protection. In general, LED displays, LED backlights, and OLEDs are three completely different imaging technologies.

The transition of the backlight module from CCFL to LED can bring a lot of benefits, which can make the brightness of the display screen more uniform, the power consumption of the product is lower, and the shape can be thinner and lighter. However, W-LED (white LED) backlights are commonly used in the market. In fact, such backlights only replace the components that emit light, and the display effect is very weak or not improved. The RGB-LED (three-color LED), which has a significant improvement in the display performance of the liquid crystal product, has an obvious improvement in display effect, but at the same time, the production cost is high, so it is applied to a high-priced LCD TV. At present, the LED display referred to by the merchant refers to a display product using a white LED backlight, and the difference from the ordinary liquid crystal display is the change of the backlight.
