Tutorial: Dr Pan Teaches COG LCD Display Module

Dr Pan:Welcome to DISPLAY Museum. I am Dr Pan, the curator of Museum.

Greg: Hello, Dr Pan. I am Greg. I came here to learn about COG LCD Module.

Dr Pan: Hello, Greg. COG is the abbreviation for chip on glass. It is a technology, which IC is bonded directly onto ITO glass. COG technology is usually used in small size dot matrix monochrome LCD module and TFT LCD module.
COG LCD module is so popular because of following reasons.
NO.1, it can greatly reduce the size of the LCD module because it doesn’t have PCB and it can be as thin as 2.0mm (maybe thinner). The thinner the more expensive.
NO.2, it is simple structure and easy for mass production of consumer electronic products, such as: mobile phone, PDA and portable device, etc.
NO.3, it is cost effective over COB LCD and can totally replace COB LCD in function, especially in graphic LCD modules, because it reduces the number of IC.
NO.4, for some dot matrix LCD modules, it is not possible to apply COB LCD technology because it is too crowded to place so many points on the view area. COG LCD is an economical and feasible solution because the pitch is smaller .
NO.5, it is replaceable. It is so easy to replace COG LCD module with FPC connection if it is malfunctioned.

Greg:Thank you, Dr Pan. Now I got it.

Dr Pan: Welcome to contact us if you have any question.

3 Ways to Increase the Brightness

  • increase the number of LED lamps
  • use high power consumption LED lamps
  • adopt injection light guide plate

Disadvantage

  • can only achieve simple display function.
  • have to add a PCBA if want to achieve multiple functions. It is called hybrid structure. Highly recommended. 
  • tooling fee is a little more expensive.
