What You Need to Know About LCD Displays on Your iPhone

Apple uses LCD displays in most of its iPhone models. This technology has been around for decades and is well established, but it requires a backlight that consumes a lot of power.

Another type of display is OLED, which has no backlight and each pixel lights up on its own. This has some significant benefits.


If you’ve noticed colored vertical lines on your iPhone screen, there are a few possible causes. These include LCD connections, hardware damage, static discharge, and iPhone system glitches. Apple does a great job of preventing burn-in on its OLED displays, so residual images are not as much of an issue as they might be with some other manufacturers.

Customers often ask why their iPhone screen color is different from other screens. The display color of lcd iphone is determined by the mother board IC,different brand IC make the screen show different color. APPLE use 3 suppliers for iPhone lcd screens, Sharp, JDI (Japan Display Inc.), and LG, each lcd screen has different display color. Mostly JDI and LG screens have warm color, while Sharp has cold color.


Apple’s newest iPhone models use OLED displays, which offer much better contrast than the LCD panels used in previous iPhones. Contrast is the ratio between a display’s peak white brightness and its darkest black luminance, and it’s one of the most important measurements of a screen’s quality. A recent patent application filed by Apple describes a dual-layer LCD system that could provide a much higher contrast ratio than typical LCDs. It credits Jun Jiang, Cheng Chen, Gabriel Marcu and Jiaying Wu as the inventors. The image above shows a comparison of the Earth on an iPhone 7 Plus with an LCD panel (left) and an iPhone X with an OLED panel (right). The OLED display has significantly darker blacks.


The brightness of an lcd iphone LCD display can be adjusted by changing the power to the backlight. This adjustment affects the entire display and can result in a noticeable shift in colors and contrast. It can also cause a bright spot in the center of the screen.

With OLED displays, it is possible to adjust the brightness on a per-pixel basis. This allows for greater flexibility in setting lcd iphone the display to match the environment and reduce eye strain. The OLED displays are also more responsive to changes in ambient light, resulting in less battery consumption.

In addition to reducing eye strain, the OLED displays are also more resistant to burn-in than LCDs. This is especially important for high-resolution displays that have been in use for long periods of time.

However, it is important to note that a number of factors can affect the brightness of an iPhone. For example, it is common for screen protectors to dim the display. It is also possible that the screen may be damaged or cracked. In either case, it is essential to check the iPhone’s settings to see if Reduce White Point is enabled.

Response Time

In order to maintain a good display quality, the response time of an lcd iphone must be fast enough to respond to user input. This is typically measured in milliseconds (ms). The faster the response time, the better the display quality.

Another important consideration for an lcd iphone is the brightness at a certain angle. While LCDs typically experience a significant decrease in brightness when viewed at an angle, OLED screens tend to perform much better. In fact, the OLED iPhone 13 Pro Max has such a small decrease in brightness at 30 degrees that it is practically impossible to detect.

It is also important to note that although there are a few manufacturers of bare LCDs, these are sold to countless other companies who add the remaining components necessary to create a functioning screen. This means that you could have an LCD from the best “copy” manufacturer but the touch/digitizer from a company with a poor reputation.
