What’s the Difference Between iPhone X High Copy LCD VS Original OLED?

LCD VS OLED?

lcd vs oled

LCD screens like those used in previous iPhones and the new iPhone 8 and 8 Plus are built on a backlight—a panel as large as the screen itself that produces a constant white light anytime the screen is on. A series of polarizers and filters are layered in front of the backlight to control the light and produce the image you see on screen. It’s been the dominant technology used in flat-panel displays for almost two decades, but keeping that backlight on draws a lot of power—and that’s a big disadvantage in a portable device.

An OLED does away with the backlight completely. Each individual pixel has a tiny amount of organic material that fluoresces when current flows, so the pixels produce light directly. It’s also possible to control brightness at a per-pixel level.

Comparing from the back, there’s still a big difference.

First is color difference between the camera lens coating.
Second is liquid crystal drive ic, high copy is smaller than OEM.
The last is high copy screen doesn’t have four connector contacts, which may have an impact on the signal.

2. Comparing the thickness

The high copy screen looks thicker than the OEM which will have an impact on the appearance after installation.
Through measuring, we can find that the high copy screen is about 0.6mm thicker than OEM screen. After installation, the high copy screen are thicker than OEM one too.

3. Testing brightness

OEM screen has high brightness and uniform display, while high copy screen has dark display, on the white screen interface, there are clear shadows under the edge of the corner.

Comparison in material:

Material Original Screen High Copy Screen
LCD Panel OLED (General No Heat) TFT (Need Backlight)
Flex Cable IC Original Drive IC High Copy Flex Cable and IC
Glass lens Original High Hardness Corning Glass Ordinary Glass material, Poor Hardness.
Frame Original High Copy and Rough workmanship
Backlight NO Yes, Backlight works with a lot of heat.

Taken altogether, Let’s make a contrast in function:

1.Before light up the screen, the high copy screen has obvious boundaries between display and non-display area.

2.After light up the screen, high copy screen has dark display and color distortion, The edge of the display area will have varying degrees of brightness difference.

3. When you start using it, Screen Touch and 3D Touch function work well, but the high copy screen is getting hot and touch sensitivity declines. If you are playing games just right, you will crazy.

4. As high copy LCD needs backlight, so the power consumption is faster.

5. In terms of handfeel, high copy screen is poor than original owing to screen thickness. It is more easy to appear white spots.
