Difference between iPhone XR COF and COG LCD Screen

1
What is the difference between iPhone XR COF vs
COG LCD Screens?
2

• The growing demand for alternative options in
  display assembly for iPhone XR, has allowed the
  Market to respond with several options.
• These options have created certain confusion
  within the industry on what the differences are
  such as quality, brightness, possible issue, and
  more. While many of them might look alike, the
  structure might differ greatly which has an
  impact on price.

• COG means chip on glass
• COF means chip on flex.
• COF LCD assemblies are totally different than COG
  LCD assemblies because they have an IC Chip that
  is bonded to the flex versus being adhered to the
  glass. This feature provides many benefits such
  as higher reliability, less damage, better heat
  distribution, reduced weight, and more.

• We release COF LCD Screen with Aftermarket Plus
  Quality and COG LCD Screen with Aftermarket
  Quality. Dont forget our Premium quality LCD
  Display for iPhone
• COG is going to have the brownish cable, there is
  not going to be any IC right on the flex. COF
  its will have the Driver IC right here, this is
  kind close to the OEM spec is for iPhone XR. When
  the IC driver is on the bottom of it, because
  its going to be little bit smaller, thats one
  of the biggest downfalls for COG.
• COG and COF has digitizer separated from the LCD.
  And also both are TFT LCD Screen.
