graphic monochrome lcd module quotation

Liquid crystal display (LCD) is a flat panel display that uses the light modulating properties of liquid crystals. Liquid crystals do not produce light directly, instead using a backlight or reflector to produce images in colour or monochrome.

Each display can be configured in your choice of LCD mode, LED backlight type, and viewing angle. These monochrome LCDs are ideal for industrial and consumer applications where high stability and low-power consumption is a priority.

Our monochrome LCD displays can be configured to suit your product"s application with RGB LED backlights, low power backlights, single color backlights, or no backlight.

Displaytech offers a full line of monochrome COG and graphic LCD modules with or without your choice of backlight. Below you will find the products that Displaytech customers prefer over any other standard single-color LCDs. Our selection of 128x64, 128x32, 128x240 and 240x64 graphic FSTN LCD modules are our most popular!

Dr Pan: Hello, Greg. In short, it consists of LCD screen and LED backlight. The working principle of LCD module is that LED backlight module emits uniform light to the surface as the light source of LCD screen and LCD screen which works as a switch is to control the light “on/off”, resulting in the display of the image.

In order to control the display content, we have to use IC to issue the commands. According to the different locations of IC, it can be divided into COG and COB LCD module. Based on the display content, it can be divided into segment, dot matrix, graphic and character LCD module.

Normally, it is much thicker than OLED since it has a backlight as the light source. It can be very thin, but the thinner it gets the more technical problems we have to solve, the higher the price will be. The advantage of LCD module technology is that it is very mature and very stable, the unit price is significantly lower than OLED’s.

Dr Pan: That is a good question. There are several factors we need to consider.Defective pixel. The less the better. LCD screen is composed of many display points. If there is no defective pixel, it is class AA; it is class A when there are less than 4 defective pixels and only 1 bright spot; and it is class B when there are less than 4 defective pixels and 2 bright spots.

Contrast rate. It means the comparison between the brightest part and the darkest part of LCD. The minimum contrast rate is 350:1, the higher the better.

Viewing angle. The wider the better. TN LCD is only 90 degree, HTN is 110 degree, STN is 210 degree to 255 degree, FSTN is the advanced version of STN with one compensation film, the view angle is better.
