Famous brands raw material selection
1. LED: well-known international brand, with wide viewing angle, high brightness, little attenuation, good heat dissipation, and vivid colors.
2. Driving IC: famous brands such as Netherland Philips, Japanese Toshiba, avoidable the defective phenomena, such as dark bright, virtual light and so on.
3. Power supply: industrial-strength brand. The power t maximum power reserve of 20% the space, the range of voltage fluctuation is less 5%, high stability.
4. Connector: aerial grade brands ensure the stable transmission of power and signal.
5. PCB Board: FR-4 A2 CCL, adopt 4-layer design.
1. High-contrast mask design: new anti-glare mask design, fine sand processing and black coating on the surface, no glare, and improve the contrast.
2. Automatic SMT: adopting high-end automatic SMT machine, advanced wave soldering and reflow soldering processing, to effectively avoid the wrong plug, plug leakage, leakage welding, virtual welding problems.
3. Module suite: improve the planeness of the whole screen, and reduce the seam between the neighboring modules.
4. Multi gray display: adopting 16bit gray processing technology to restore the natural image. And using S-PWM driving technology to add gray grade, meet the 16bits high gray display requirements with low brightness.
5. Point by point correction: the correction technology of brightness and chromaticity to ensure the uniformity of led screen’s brightness and color.
