FAQ

1.Comparison between STN LCD and TFT displays?

STN LCDs require less power and are less expensive to manufacture than TFT LCDs, another popular type of LCD that has largely superseded STN for mainstream laptops. STN displays typically suffer from lower image quality and slower response time than TFT displays. However, STN LCDs can be made purely reflective for viewing under direct sunlight. STN displays are used in some inexpensive mobile phones and informational screens of some digital products.

2.What are the Installing Precautions

The hole in the printed circuit board is used to fix LCM as shown in the picture below. Attend to the following items when installing the LCM.

(1)Cover the surface with a transparent protective plate to protect the polarizer and LC cell.



(2)When assembling the LCM into other equipment, the spacer to the bit between the LCM and the fitting plate should have enough height to avoid causing stress to the module surface, refer to the individual specifications for measurements. The measurement tolerance should be 0.1mm.

3.What is the difference between COG and COB ?

COG LCD modules can be more compact, reliable, cost effective, and require a lower currency than COB LCD modules.

4.How long can we expect the samples?

Answer: Most of the time, we have samples in stock. If not, it only take 1-2weeks for us to get samples ready.
