When the machine is turned on, the client describes it as extended beeping, beeping, short-circuiting, and light leakage. It is as a result of the pull lines in the LCD being coupled together even though they shouldn't be. Some of the bytes presented in the module are comparatively light or absent because the huge current is limitless (the electrical measurement scan will be called).
The module's display is dim or fuzzy, or the battery is quickly discharged. If there is power, it can be assumed to be normal, and electrical measurements show a substantial current.
This is what the client refers to as a short stroke, missing stroke, and hyphenation. In actuality, the ITO is scratched, disconnected, and the module likewise exhibits the missing stroke.
This is when characters displayed on the module that shouldn't be there appear faintly when they aren't illuminated, the word depth is under the same voltage as the sample, and the word is viewed in the same way as the sample. You can see how the contrast is affected.
Some bytes that are being displayed are lighter than others. The bytes are uneven because of the irregular level of ghosting in the bytes that are not displayed.
Customer calls it "flickering," "byte flickering," "fuzzy byte," "poor contact," "shaking," "incomplete display," "half display," and "missing stroke." Because of the poor conductivity, which is seen during electrical measurement at normal voltage, this is the cause. Nearly one byte or a specific portion of a byte is shown inconsistently, blurry, or not at all. The difference between a "open circuit" and an electrical measuring device is that after testing and voltage adjustment, the latter can display normally once more.
Customers frequently complain about uneven grayscale, displays, bytes, white spots, black spots, and stains... There will be small white or black dots on it when the electrical test indicates that a particular byte is shown. And these tiny dots typically change in size in accordance with the frequency of the electrical measuring device, the voltage's magnitude, and the module display. Therefore, it is crucial that the factory ascertain that the uneven surface represents the module's frequency output voltage.
Customers describe it as having missing words and bytes.
what clients refer to as black stains, threads, and spots. shows that the LCD has fibers.
Customers refer to it as inconsistent color and rainbow, which refers to the fact that the color of the LCD is unbalanced, as well as rainbow in the middle or rainbow, and unbalanced color stripes, mostly in terms of color.
In general, this LCD's overall color differs significantly from the overall colors of other LCDs. Generally speaking, the existing process capabilities of our facility cannot match the samples.
This is where the so-called conductive layer, which is the PIN on the LCD's side, has been sliced, resulting in an open circuit and poor conduction. When a client fixes anything, it is simple to cause.
The mirror surface is hazy and the polarizer is scraped and perforated; the consumer calls it a mirrored flower. That is, due to poor positioning and use by customers, the polarizer is broken or destroyed by hard hands like knives.
The lighting is required to observe the polarizer's stripes. After applying the patch, the conductive layer becomes stained with alcohol or acetone. When the client wipes the PIN, more infiltration may occur.
No protective film, i.e., the protective film covering the polarizer's surface has been peeled off. (Typically, the IC is damaged. It is assumed that the LCD is cracked and removed during repair.
After patching, there are small bubbles in the polarizer that impede the LCD's usage. Try to persuade buyers to tolerate this.
The customer refers to this as improper sticking, and it occurs when the polarizing film adheres to the top piece instead of the bottom piece as it should.
The LCD surface may have fibers, dust, and other contaminants fall on it, or dirt on the patch may have caused the polarization.
The polarizer corrodes through a chemical reaction with some liquids and changes color or shape as a result.
Products of various sorts and properties are combined, as are some versions with various models, some LCDs from various eras, and some LCDs from various manufacturers. The logo on the LCD conductive layer serves as the standard of comparison.
