white dots on lcd screen supplier

If you find yourself in a situation where you notice white spots or dots on the TV screen, don"t worry. This problem is known to occur on most LCD TVs and is really simple to fix. The white spots you notice are the LED backlight light inside the TV.

Due to frequent use or poor quality, some parts inside the TV may move out of their position and cause white spots or dots to be projected on the screen. In this article we will explain why this problem occurs and how to fix it. So let"s get started.

So what are the causes of white spots or spots on the TV screen? White spots or spots on the LCD TV are the result of a dropped reflector (lens) inside the LCD TV panel. These reflectors are placed in front of the LED backlight and are used to spread the LED light across the screen. They usually fall out due to poor quality or the heat created inside the TV.

When you open the TV you will find a series of LED lights covered with reflectors or plastic lenses. These lenses are mostly glued in front of the LED backlight, and as the TV gets hot with use, they start to fall off their spot and create white dots or spots on the TV screen.

As we said above, these white spots or spots on the TV screen appear very often due to overheating issues and poor screen quality. Anyone who has paid attention knows that older TVs are practically unaffected by this image error.

This problem is mainly found in televisions with LED backlighting, more precisely the so-called side LED backlight. Behind the panel is a light conducting plastic plate.

Dead Pixel: Each LCD and LED TV is made up of millions of pixels or dots whose main purpose is to illuminate and produce the image on the TV screen. Sometimes, the problem can occur if some pixels are damaged and get stuck in a particular state that is causing the problem and appear as white spots on the TV screen.

LED Reflectors: Each LCD TV is equipped with a reflector (lens) which helps to facilitate and diffuse the LED light on the screen. Sometimes, these spotlights loosen and fall out of place. When this happens, you will notice the white bright spot on the TV screen. In most cases, you will have several white spots or smudges on the screen, not just one.

To solve the problem of white spots on the TV screen, you will have to open the TV and with the help of the super fast glue you will have to put the fallen reflector back into place.

Note! You can also press Pause during a movie when the screen is black to test the LCD TV to see if there are any white spots or spots on the TV screen.

White spots (dots) on the TV screen are a very common problem on LCD TVs. Almost all LCD TVs operate using a small chip made up of millions of tiny mirrors. Each mirror is like a dot or a pixel on that screen.

When the spotlight or lens moves from its original position, these white dots appear on the screen. But in some cases, there may be more damage to the TV screen than a simple displaced spotlight or dead pixel, and it can cost you more than a new television.

Therefore, it is recommended to contact a specialist if you notice that the problem is not only with the displaced reflectors but something more. Please note that if your TV is under warranty, it is recommended that you contact a service center and let them take care of this issue.

This could mean that something isn’t assembled correctly inside of the phone and is pressing against your display panel. You can easily test this by opening the phone again and to not press it into the case. If you still see white dots it probably means that your display got damaged during installation or that it was damaged before installation.

I noticed something similar on an iPhone 7 Plus I worked on where the display flex cable was not correctly routed under the shield of the screen, causing some pressure on the screen resulting in similar white dots when touching on the display. Take a look at the screen replacement guide as of step 34 to double check your cable is routed properly. I’m saying this because the white spots in your pictures happen to match the placement of the ribbon cables.

Thanks guys! I just replaced the leds for my tcl 55 inch tv and after bout a week I started seeing the bulbs on the left side of the screen. Since the tv was an awesome find and the bulbs were like 30 bucks on eBay I’m fighting the inevitable being going back in and fixing that plastic deflector post. The screen is extremely fragile so if u don’t wanna pay 14 bucks at Home Depot for them window suction cups that were well worth the money For loners like myself lol, make sure u get another person to help u with the screen panel once it’s been dislodged . Especially if it’s a big honker. Nothing more scary than popping it out by urself and get stuck in a very bad situation as in u can almost hear the crackin of the screen Or knowing that I’d u take one more step this here screen will crack .

Liquid crystal display (LCD) screens are made up of millions of small colored spots called pixels. A small white spot on the screen is called a white pixel. This white spot is also known as a stuck pixel. Stuck pixels can appear on any LCD screen, including laptops, monitors, and cell phones screens.

Common causes of a white pixel include a malfunctioning transistor or uneven distribution of liquid inside the LCD monitor. Each pixel has three sub-pixels in red, green, and blue. Transistors carry electric current to the sub-pixels. The current makes the pixels change color.

If a transistor shorts out or remains open, the result can be a white, red, blue, or green pixel. If the pixel is not getting any current, then a small empty black spot surrounded by white space may be seen on the LCD screen. The black space is called a dead pixel.

Sometimes, a white pixel can be repaired. Various software programs are available that may find and fix white pixels. Generally, software can run a complete pixel test, or search by pixel color to find a white pixel. Software can take anywhere from 20 minutes to a few hours to test all the pixels.

Rubbing or tapping the screen may also repair a stuck pixel. Users can try to repair pixels at their own risk. Care must be taken when attempting to repair a pixel by tapping or rubbing the screen. It is possible to break other pixels surrounding a white pixel.

Monitors should be turned off prior to rubbing or tapping on the screen. Placing a damp cloth on the screen may help prevent scratching and further pixel damage. The screen can be turned back on while still applying pressure to the screen. Users can then remove the pressure and the cloth to see if the white pixel has been repaired.

White pixels may also start working over time without any attention from the user. Some white pixels appear only after several hours of continued use. Generally, white pixels are an annoyance and do not stop the screen from working properly.

Manufacturers each have their own pixel policy regarding LCD screen replacement. Companies rarely replace monitors with a single white pixel. Users can check their warranty information to determine how many white pixels are required before the manufacturer will replace a screen under the original warranty.

Some companies may replace screens with pixel defects with a refurbished unit. Users can call the company’s customer support center to find out if a particular screen will be repaired or replaced. Customers may also choose to live with a single stuck pixel, with the hope that it will repair itself over time.
