LCM design time to consider what problems? What do you want to pay attention to? Below and LCD LCD module to see it.
In fact, a module design is mainly divided into 2 parts, one is the glass and backlight, and the other is the PCB version, of course, the COG series except.
And the display of this piece is the most important embodiment.
For example:
Temperature and time of wave soldering
It is suggested that the temperature and the time of the wave front welding should be controlled at 100, the highest temperature is 5, and the maximum is 120, and the temperature of the preheating temperature is stable.
For 245 C + 5, no more than 3 seconds for the welding time, avoid vibration or shock LED, until the restoration of normal temperature state. The temperature parameter of the wave crest welder should be detected regularly, which is made by the
LED the characteristics of the decision, overheating or fluctuations in temperature will directly damage LED or cause LED quality problems, especially for small size such as 3mm's circular and oval LED.
Mixed light
The same color of different brightness file LED need to mix, or in accordance with the discrete design of the plug in a lamp, to ensure that the entire screen each color brightness consistency. This process
If there is a problem, it will appear the phenomenon that the local brightness of the display is not consistent, which directly affects the display effect of the LED display.
Good verticality control lamp
For in-line LED, a furnace to have enough technology to ensure LED perpendicular to the PCB board. Any deviation will affect the LED brightness has been set to a good consistency, appear bright
Are not the same color.
