2. Understand the key parameters of LED display screens
The key parameters of LED display screens are crucial to their display effects and user experience. The following is a detailed explanation of these key parameters:
1). Resolution:
The resolution of LED display screens refers to the precision of the screen image, that is, the number of pixels that can be displayed on the display screen. It is usually expressed as the number of horizontal pixels × the number of vertical pixels.
The higher the resolution, the clearer the displayed picture and the richer the details. Choose the appropriate resolution according to the usage scenario and budget.
For example, for advertising displays in small stores, standard definition or high definition resolution may be sufficient; while for home theaters, game enthusiasts or professional image design fields, 4K or higher resolution can bring a better visual experience.
2). 刷新率:
The refresh rate refers to the number of times the screen refreshes the image per second, usually in Hertz (Hz). The higher the refresh rate, the more stable and smooth the picture display, the less visual flickering, and the higher the image clarity.
For general applications, a refresh rate ≥1920Hz can meet the needs; for high-end applications, such as live sports events or professional film and television production, a refresh rate ≥3840Hz can bring a better visual experience.
3). Screen size:
Screen size refers to the diagonal length of the LED display, usually in inches or millimeters. The choice of screen size directly affects the viewing effect and user experience. Choose the appropriate screen size according to the usage scenario and viewing distance.
For example, in an indoor conference room, a smaller screen size may be more suitable for close viewing, while in an outdoor billboard, a larger screen size can attract more attention.
4). Brightness:
Brightness refers to the intensity of light emitted by the LED screen, usually in nits. The higher the brightness, the clearer the screen can be seen under strong light, ensuring the visibility of the content.
The brightness of indoor LED displays is usually between 800-1500nits, while outdoor LED displays usually have a brightness between 3000-6000nits because they need to resist direct sunlight.
3. Consider the price of the budget and the cost-effectiveness of the LED display
When considering the budget and the cost-effectiveness of the LED display, here are some suggestions:
1). Clear budget
First, you need to clarify your budget range. The price of an LED display varies according to parameters such as size, resolution, brightness, refresh rate, etc., so you need to choose the right product according to your needs and budget.
