4 tips to avoid dark spots when buying liquid crystal display

1. What is the LCD liquid crystal display's dark spot?

Dark spots are, in a sense, more difficult to see than flash points and pixel points, yet they affect everyone far more negatively than pixels do.

On numerous LCD screens, there may occasionally be a lot of little spots. The LCD monitor's small dark spots are around the size of soybeans, while its larger dark spots are probably about the size of a thumb.

The dark spots are only somewhat darker in local color matching, which makes it difficult to find them when viewed from the front and only possible when viewed from the side, in contrast to the flash and dark spots.

We believe it is quite likely that the black spots manifest as a result of incorrect handling throughout the shipping procedure. The main cause of the formation of dark spots may be the long-term extrusion of external force.

Dark spots on an LCD liquid crystal display are typically hard to discern from the front, but they are rather noticeable from the side.

When purchasing an LCD display, it is advised against simply looking at the LCD to identify the pixels. To prevent the dark spots from hiding, you should observe the screen surface from various angles and set the screen to white.

2. What factors need to be taken into consideration when buying a high-brightness LCD display?

Because we can view a high-brightness LCD panel at any time in life, we should be familiar with its characteristics, which vary depending on the situation.

When purchasing LCD liquid crystal displays, many individuals are confused because they don't comprehend this concept. Let's examine the purchasing process for this high-brightness LCD display:

Brightness homogeneity of the backlight on LCDs

High-brightness screens typically fall into one of the following three categories for uniformity: uniformity reaches 65%-75%, uniformity reaches 75%-85%, and uniformity can reach more than 90%-95%. Of course, a good job will cost more money.

Brightness of an LCD display

High brightness is a characteristic of good LCD liquid crystal displays, but the images are soft and do not strain the eyes. Not as bright as the backlight (which, like the sun, is bright but also dazzling).

The brightness value is a color range value that is influenced by the screen's backlight's illuminance, contrast, and color saturation. Because the human eye perceives illuminance, which is influenced by the environment, space size, etc., and can only be measured with an instrument, seeing a very bright screen may not produce the desired brightness value.

3. The temperature at which the high-brightness LCD panel dissipates heat

When choosing a high brightness LCD screen, buyers should consider temperature. Excellent LCD liquid crystal display with great brightness, minimal heat generation, and minimal power usage. The LED backlight's service life is shortened by the faster light degradation that occurs at higher temperatures.

4. The manufacturer's professionalism

Not only is a high-quality, bright LCD panel a fantastic light source, but it also makes for poor packaging. The LED heat dissipation process, light directing process, and light efficiency are all subpar when the light source is good.

Customers should therefore consider the manufacturer's expertise when selecting a good bright LCD screen. Only skilled producers are able to meticulously create LCD display products that are qualified.
