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.

    Today, we are going to show you [How to replace an iPhone 5S lcd screen assembly and transfer the front camera, home button, and ear speaker.]

    1) Begin by removing the two pentalobe screws from the bottom of the phone.
    2) Next, use your suction cup and prying tool to lift out the screen.
    3) Before completely removing the screen assembly, we must disconnect the home button connector located near the charging port.
    4) Continue to lift the screen to about a 90 degree angle and remove the screws from the metal connector shield.
    5) Next, use your prying tool to disconnect the three lcd screen connectors.
    6) Once the old screen is removed, unscrew the front camera shield and the screws holding the Metal LCD shield in place.
    7) Remove the screws on the metal home button assembly.
    8) Use your prying tool to lift out the home button flex assembly. (This step may require a heat gun on the front side of the home button to loosen the adhesive).
    9) Continue to pry off the copper adhesive on the metal LCD shield in the upper left corner.
    10) Next, remove the metal ear speaker frame and assembly.
    11) Use your prying tool, lift out the metal LCD shield from the old screen.
    12) Heat the front of your LCD screen and use your prying tool to separate the front camera assembly.
    13) With the upper lcd frame still warm, use your metal prying tool to remove the plastic camera placeholders.
    14) On the new LCD screen you want to install, re-insert the two plastic camera placeholders.
    15) Continue to reinsert the front camera assembly.
    16) Place the ear speaker on the new screen and screw in the metal frame.
    17) Remove the LCD protector and install the LCD frame with its supporting screws.
    18) Insert the iPhone 5S home button onto the screen assembly.
    19) With the home button in place, attach the metal home button shield.
    20) Now, with the new replacement screen ready to go, we can connect the LCD, digitizer, and front camera ribbon cables.
    21) Snap the lcd protector shield in place and screw in the remaining screws.
    22) Do not forget to reconnect the iPhone 5s home button ribbon cable.
    23) Proceed to firmly snap the new lcd replacement screen assembly onto the iPhone housing.
    24) Finally, we can re-insert the two pentalobe screws into the bottom of the iPhone locking your new replacement screen in position.
