What are the precautions for customizing LCD screens?

First, determine the demand for customized LCD screens
Understand the needs of terminal buyers, including specific needs for LCD screen size, resolution, brightness, interface, appearance size, AA area size, PIN definition, temperature range, service life, touch screen, etc.
It should be noted that we need to make a demand list and send it to the LCD screen manufacturer. The more detailed the better, the more conducive to subsequent mold opening work. It is best to provide corresponding drawings, which will save a lot of time in early communication. cost.

Second, confirm the LCD screen drawing
LCD screen manufacturers generally design and issue drawings to end buyers for confirmation within one week after receiving the demand. It is important to note that the items to be confirmed include appearance design drawings, drawing modifications, mold production, design layout, Photolithography film production (electrode x2, frame, silver dots, PI, test PCB), screen printing screen, relief plate, test frame series. Finally, sign the confirmation drawing so that the LCD screen manufacturer can send it to the relevant supplier for mold opening and customization.

Third, confirm the LCD screen sample

After confirming the drawings, the LCD screen manufacturer will make arrangements. Generally, they will report a specific proofing cycle, which mainly depends on the difficulty of product production. Generally, the proofing time of the module is about 20 days, and the proofing cycle of the assembly is 25 days. About days.
After receiving the sample, the LCD screen manufacturer will generally undergo strict testing before sending it to the terminal buyer. The terminal buyer can also retest the sample after receiving it, and conduct debugging to confirm that there is no problem with the sample, and can sign for confirmation. The samples are sent to LCD screen manufacturers for small batch production.
