Special-shaped green hair Emerald Green Led Lamp Beads

The full-color display is composed of countless red, green, and blue LEDs. The brightness and wavelength consistency of each color LED determines the brightness consistency, white balance consistency and chromaticity of the entire display. Sex. Generally speaking, display screen manufacturers require device suppliers to provide LEDs with a wavelength range of 5nm and a brightness range of 1:1.3. These indicators can be achieved by the device supplier through a spectroscopy machine. The consistency of voltage is generally not required High-power LED.

　　Because the LED is angled, the full-color LED display also has angular directionality, that is, when viewed from different angles, its brightness will increase or decrease Illumination LED. In this way, the angle consistency of the red, green, and blue LEDs will seriously affect the consistency of the white balance at different angles, and directly affect the fidelity of the video color of the display screen. To achieve the matching consistency of the brightness changes of the red, green, and blue LEDs at different angles, it is necessary to strictly carry out scientific design in the package lens design and raw material selection, which depends on the technical level of the package supplier. No matter how good the white balance is in the normal direction, if the LED angle is not consistent, the white balance effect of the whole screen at different angles will be bad. The angle consistency characteristics of Led Lamp Beads can be measured with a comprehensive LED angle tester, which is particularly important for medium and high-end displays Patch Light Emitting Diode.
