How to identify the quality of LED display

In today's digital era, LED display screens have become an important medium for information dissemination and are widely used in advertising, information display, stage background and other fields. However, the quality of LED displays on the market is uneven, and how to identify their quality levels has become the focus of users. The following are some professional methods to help users identify the quality of LED displays:

Brightness

Brightness is one of the most intuitive indicators of a display. Different application environments have different requirements for brightness:

Indoor display: about 1000nit Outdoor display: higher than 6000nit Semi-outdoor display: 2500 to 5000nit Small spacing display: 100 to 300nit

The brightness should be adjusted according to the viewing distance and ambient light to ensure the image is clear and not irritating to the eyes. How to adjust the brightness and contrast of LED display?

Color temperature

Color temperature affects the realism of an image. For direct viewing, the color temperature value is recommended to be between 6500 and 8000K; for TV broadcasts, it needs to be adjusted to about 5500K to ensure that the picture recorded by the camera is realistic.

Perspective

The width of the viewing angle determines the viewing range. The horizontal viewing angle of an indoor full-color screen should be greater than 140 degrees, and the vertical viewing angle should be greater than 100 degrees; the horizontal viewing angle of an outdoor full-color screen should be greater than 100 degrees, and the vertical viewing angle should be greater than 90 degrees. Color consistency should be maintained across different viewing angles. How much does an indoor LED display cost this year?

Grayscale

The gray level determines the layering of images presented on the display. In the industry, the grayscale level can generally reach 16BIT, and higher levels can provide more delicate image performance.

Refresh rate

A low refresh rate will cause the screen to flicker, affecting the viewing experience. The display refresh rate should be no less than 300Hz, and for camera equipment, it needs to be above 2000Hz.

Contrast

High contrast provides clearer, more transparent images. The contrast ratio value should not be less than 1000:1, which is related to the packaging of the LED light and the design of the module mask.

Uniformity

The brightness and color uniformity of the display affect the overall visual effect. Through testing in RGB monochrome and white states, the consistency of brightness and color can be evaluated.

Performance identification

In addition to the display effect, the performance of the display is equally important:

a, pixel out of control point

Pixel out-of-control points include blind spots and bright spots. The out-of-control rate of small-pitch screens should be controlled below 1X10^-5.

b. Protection level and safety

The protection level mainly refers to waterproof and dustproof. The higher the IP value, the better. Safety includes leakage current and electrical strength to ensure safe and stable operation of the equipment. Take you 5 minutes to understand LED IP levels.

c. Energy consumption and energy efficiency

Reducing power consumption and improving energy efficiency are the keys to extending the life of the display. Energy efficiency can be improved through designs such as low Vf value LEDs and low Vds value constant current driver ICs.

d.reliability

Displays with poor reliability have a high failure rate, which affects the user experience. Everything from material selection, thermal design, redundancy design, material tolerances to reliability testing should be strictly controlled.

Through the above methods, users can more comprehensively evaluate the quality of LED displays and choose products with high cost-effectiveness. At the same time, it is also recommended that users consult professionals when purchasing, or choose reputable brand manufacturers to ensure investment benefits.
