COG LCD Display Modules(Chip-On-Glass)

Chip-On-Glass (COG LCD Display Modules) is a flip chip bonding method which is used for connect assembly of bare integrated circuits (ICs) on glass substrate directly by using Anisotropic Conductive Film (ACF). The pitch of the IC bumps (footprint) can be scaled down according to customers’ requirements (contact pitch of glass substrate). This method reduces the assembly area to the highest possible packing density, which especially important to those applications that space saving is crucial. It allows a cost-effective mounting of driver chips because integrating flex PCB is no longer required. The IC is bonded directly onto the glass substrate and is suitable for handling high-speed or high-frequency signals.

COG LCD Display Modules technology is one of the high-tech mounting methods which use Gold Bump or Flip Chip IC’s, and implemented in most compact applications. Chip-On-Glass integrated circuits were first introduced by Epson. In flip-chip mounting, the IC chip is not packaged but is mounted directly onto the PCB as a bare chip. Because there is no package, the mounted footprint of the IC can be minimized, along with the required size of the PCB. This technology reduces the mounting area and is better suited to handling high-speed or high frequency signals.

COG is primarily used for source driver ICs within TFT display technologies where they are used for LCD, plasma, e-ink, OLED or 3D technologies. This is essential for consumer electronic products such as notebooks, tablets, cameras or mobile phones with the need for small size and light-weight components.

Advantages: 

Very economical on size. Chip-On-Glass LCD modules can be as thin as 2 mm.

Cost effective over COB, especially in graphic LCD modules, because reduces the number of IC’s.

More reliable than TAB due to TAB’s weakness in the bond area.

Disadvantages: 

COG can only be used at a certain resolution level where the lines are not too fine. At very fine pitches COG becomes difficult to test, and TAB would be the preferred approach.

It may be more cost-effective to use TAB or COB, if a designer has to integrate a keypad or indicator around the display.

The active area is not centered within the outline but offset, because of the area where the circuits are.

    Unboxing and Installation of the 2.5x Carry Speed LCD Viewfinder on my Nikon D5100. Was just under $30 on eBay.

    The Magnetic attachment is very strong – pulling on it will swivel out the LCD Display. It also has small tabs that mate with the metal bracket so will attach in the same position, wont slide around on the back. I have a CGS Glass Screen protector on my LCD and the megnetic bracket sticks to it no problem and it still has a full field of view even with the slight increase distance between LCD and lens.

    Works very well, image is good, fills the field of view and covers the entire screen – makes it much easier (for me) to focus.

    Inside is covered in felt type material to stop reflections, but I had bits of it all over the lens. Cleaned off no problem but I don’t know if it will keep “shedding” as its still new.

    Timely delivery, strict implementation of the contract provisions of the goods, encountered special circumstances, but also actively cooperate, a trustworthy company!
