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.

    Hi there,

    I found out something today that I felt I had to share this with you guys.
    When I got in this morning I discovered a rather nasty scratch running down my LCD monitor screen (A lovely present from the kids!!)
    Obviously I wasn’t too pleased and wondered what I could do to fix it, searching the net I read about a technique using Vaseline and although I was a little dubious about the claims made I thought that I would try it out on one of my older monitors first.

    I hadn’t got any Vaseline in the house so thinking about things with a similar texture I instantly thought of chapstick, I found one of my wifes Derma original tubes and that is what I used, I can tell you that it may not be Vaseline, but I have to say “Wow!” the results are amazing so I thought I would demonstrate on camera to share this tip.

    First wipe the area with an alcohol based cleaner to clear the screen of smudges and dirt, apply the Derma stick along the length of the scratch then using a circular motion, rub the chapstick residue well into the scratch before wiping off the excess with a clean lint free cloth and that is it, simple, fast, but very effective.

    Although you may still see the scratch when viewing the display from obscure angles, it is much less noticeable if not even totally invisible from the front, normal viewing position.

    This tip has saved me having to shell out for a new screen and I hope it will prove useful to someone else out there with a similar problem.

    Thank you for watching.

    It's really lucky to find such a professional and responsible manufacturer, the product quality is good and delivery is timely, very nice.
