How can I check my mobile screen quality?
Brightness Control: There are two methods for changing the brightness of a smartphone display (increasing or decreasing it).
PWM DC Dimming (Pulse Width Modulation):
You are capable of handling things on your own. Simply glance at your smartphone’s display through a different smartphone camera. The smartphone is employing PWM at that brightness if there is a flicker, as shown in the left image. The smartphone employs DC Dimming at that brightness if there is no flickering, as shown in the right image.
Several smartphones employ PWM for lower brightness levels and DC Dimming for high brightness exceeding 50%. To provide us with the finest experience, Apple implements this in the iPhone XS. Hence ICFix Service provides Mobile chip-level training courses in Chennai.
Brightness Distribution: Every smartphone display has multiple brightness zones. Each brightness zone is brighter than the others in some way. The brightness distribution is better the brighter these zones are similar to one another. Just have a look at how the various zones differ in brightness. For a good smartphone display, the brightness distribution should be greater than 90%. Most cell phones’ brightness distribution can be examined with Notebook Check.
Dead and stuck pixels are the most frequent problems with Android phone screens. Stuck pixels are color pigments of the display that are frozen, and unable to convert to other hues as they should be. Dead pixels are caused by small color pigments of your screen that break, leaving a black spot on your screen. If you can identify the problem when it’s still not too bad, these problems can be easily prevented. Because of this, testing your LCD display is crucial and must be done periodically to prevent any problems from getting worse.
The primary purpose of a Display Tester is to evaluate the quality of the screen on our phone, regardless of its shape, as well as to find any potential flaws that we may have suspected or were unaware of.
Information, tests, and basic burn-in repair are the three primary components of Display Tester, leaving developer tools as a separate selection. The first one only offers details about our screen, such as its size, resolution, density, or refresh rate.
If we pass the fundamental tests, this is where you’ll find the application’s core and the section I use the most, which will be provided. This section contains all the information necessary to determine the screen’s quality and whether it is defective. In actuality, the first test is used to find dead pixels or damaged displays of solid colors.
Additional tests that we can run include “Multi-touch,” in which we will place fingers to see how many of them are identified (most screens should detect at least 10 fingers), or “Angles of Vision,” a quick way to see how much quality you lose the image when you gaze at the screen from different angles.
Another intriguing test that can be carried out involves coloring the entire surface of the green, which is a touch test. This test allows us to determine if there is any area of the screen where the touch functionality has failed. There are additional tests, all of which are free, but the ones listed above are the most significant, particularly if you are searching.
