您的计算机屏幕或显示器由数百万个经过精心编程的称为像素的微小光组成，它们会创建您所看到的图像。像素内是发出RGB(RGB) （红色、绿色和蓝色）颜色的子像素，当它们完全点亮时，会发出纯白光，而其他颜色则通过改变三种颜色中的每一种颜色的水平来发出。
每当这些子像素之一卡在一种颜色（红色、绿色或蓝色）上时，就会出现卡住像素，并在显示器上显示为持久的亮点
卡住(Stuck)的像素与坏点不同，无论显示器上的图像如何，坏点始终保持黑色，因为没有光线到达这些像素。它们也很难修复，有时您必须更换显示器。
不过值得庆幸的是，您可以使用坏点测试来诊断和解决显示器问题，(diagnose and troubleshoot problems with your monitor)以使用多种方法和软件修复卡住的像素。
什么导致卡住像素？(What Causes Stuck Pixels?)
自从LCD(LCD)（液晶显示器）屏幕出现以来，故障或卡住的像素一直困扰着显示器。
卡住(Stuck)的像素是顽固的小方块，始终保持单一颜色，但它们并不总是永久性的。它们是由硬件问题引起的，通常是由于制造缺陷（例如组装错误）或由持续开启的晶体管引起的，这可能会影响像素或其三个子像素之一。
例如，如果在基板玻璃上未正确制造有关像素的某些东西，从而导致电气故障。但在大多数情况下，当像素卡住时，并不一定意味着整个像素都损坏了。可能只是一个或多个子像素在像素中形成颜色组合。
在您返回商店进行更换或维修之前，您可以采取一些措施来解决问题。我们将向您展示如何修复坏点以及如何执行坏点测试以修复显示器上的卡住像素。
卡住像素和死像素之间的区别(Difference Between a Stuck Pixel & a Dead Pixel)
滞留像素以其子像素形式的三种颜色之一出现，即红色、绿色或蓝色。如果您发现一个奇怪的像素并且它是其中一种颜色，那么它就是一个卡住的像素。
另一方面，坏点看起来像黑色的小矩形，因为它们的子像素由于晶体管损坏而完全关闭，这意味着没有为像素供电来点亮它们。
但在某些情况下，黑色像素可能会被卡住，不一定是死的。主要区别在于卡住的像素会永久开启，而坏点则不会再开启。与很少复活的坏点不同，卡住的像素只是顽固，并且可以对不同的补救措施做出反应。
如果您看到的是白色或彩色像素，请尝试下面列出的一些方法来修复它。
如何修复显示器上卡住的像素(How To Fix a Stuck Pixel On Your Monitor)
1. 等一下。
2. 执行坏点测试或检查。
3. 使用压力和热量。
4.使用第三方软件刷像素。
5. 更换您的显示器。
与死像素相比，修复卡住的像素更容易，因为它仍然有电源，您可以将其重置为正常状态。但并非所有方法都能保证有效，因为最终取决于像素出了什么问题。
如果这些都不起作用，最后的办法是更换显示器。
等待它(Wait It out)
几个小时后，卡住(Stuck)的像素会自行脱落。有些可能需要数天或数周，有时甚至数年，但您不会等待那么长时间才能自行解决。
如果您没有耐心等待，请尝试以下其他方法。
运行坏点测试(Run a Dead Pixel Test)
坏点测试涉及通过基本颜色或黑白调色板以全屏模式运行显示器，以识别卡住的像素。
为此，请用软布清洁屏幕，然后在浏览器上打开死像素测试站点。(Dead Pixels Test)切换到全屏模式以仔细查看所有测试屏幕。
使用压力和热量(Use Pressure & Heat)
这些是通过结合压力和热量来解决卡住像素的手动方法。
开始之前，请关闭显示器，并使用湿布对卡住像素的位置施加压力，不要影响其他区域，因为这可能会产生更多卡住像素。
施加压力时，打开计算机和屏幕的电源，移除压力，然后检查卡住的像素是否消失。通常，其一个或多个子像素中的液体会穿过以产生不同的颜色并均匀分布。
加热方法包括将一块热布放在卡住的像素上几秒钟，然后关闭显示器长达 48 小时，以让像素消耗多余的电量并熄灭。
使用第三方软件刷入像素(Use Third-Party Software To Flash The Pixel)
卡住(Stuck)的像素是硬件问题，但您可以获得一个可以充当坏点修复程序的软件程序来解开像素。
您可以通过软件运行卡住的像素及其周围的其他像素，在屏幕上循环显示各种颜色。该程序将不断要求像素更改其颜色。
有几个选项可用，但您可以尝试使用JScreenF i x、PixelHealer或UndeadPixel等软件来解开像素。
JScreenFix可以帮助您修复卡住的像素，但不能帮助您找到它。要使用该软件，请在浏览器上打开该站点，然后单击蓝色的(open the site)Launch JScreenFix。它将加载一个黑色的浏览器窗口，该窗口带有一个有许多闪烁像素的正方形。
您可以通过按屏幕右下方的绿色按钮以全屏模式启动窗口，然后将方块拖到卡住像素所在的区域并让它在那里停留10分钟。
UndeadPixel是一个Windows坏点测试工具，可以帮助您使用定位器找到卡住的像素，该定位器会在屏幕上循环几种颜色。将出现一个闪烁的点，您可以将其拖放到屏幕上的坏点上并让它运行几个小时。
您还可以在测试显示器质量时运行(quality of your monitor)在线显示器测试( online monitor test)来识别卡住的像素。此测试提供了三种模式，您可以通过这些模式测试屏幕是否有滞留像素。
更换显示器(Replace Your Monitor)
如果您确实必须，这是修复卡住像素的最后手段。大多数制造商提供维修或更换保修，因此在采取此措施之前请检查您设备的保修。( check your device’s warranty)
Dead Pixel Tests To Fix a Stuck Pixel On Your Monitor
Your computer screen or monitor іs comprised of millions of carefully programmеd tiny lights known as pixels, which create the images you see. Within the рixels are sub-pixels that emit RGB (red, grеen, and blue) colors, which when lit altogеther, emit а pure white light, while other cоlors are emitted by changing the levеls of each of the three colors.
A stuck pixel occurs whenever one of these sub-pixels gets stuck on one color – red, green or blue, and appears as a persistent, bright dot on your monitor
Stuck pixels are different from dead pixels, which remain black all the time regardless of the image on your monitor, because there’s no light reaching such pixels. They’re also fairly difficult to fix, and sometimes you have to replace the monitor.
Thankfully though, you can use dead pixel tests to diagnose and troubleshoot problems with your monitor to repair stuck pixels using a number of methods and software.
What Causes Stuck Pixels?
Malfunctioning or stuck pixels have plagued monitors since LCD (liquid crystal displays) screens came on the scene.
Stuck pixels are stubborn little squares that maintain a single color all the time, but they’re not always permanent. They’re caused by hardware problems, usually from manufacturing defects such as errors in assembly, or by a transistor that’s constantly on, which could affect the pixel or one of its three sub-pixels.
For instance, if something about the pixel wasn’t correctly manufactured on top of the substrate glass, thereby resulting in electrical malfunction. In most cases though, when the pixel is stuck, it doesn’t necessarily mean the whole pixel is damaged. It could be just one or more of the sub-pixels that form color combinations in the pixel.
Before you head back to the store for a replacement or repair, there are several things you can do to troubleshoot the problem. We’re going to show you how to fix dead pixels and also how to perform a dead pixel test to fix a stuck pixel on your monitor.
Difference Between a Stuck Pixel & a Dead Pixel
A stuck pixel appears in one of the three colors its sub-pixels form, which is either red, green or blue. If you spot an odd pixel and it’s in one of these colors, it’s a stuck pixel.
Dead pixels, on the other hand, appear like small black rectangles because their sub-pixels are completely off owing to a broken transistor, which means no power is supplied to the pixels for them to light up.
In some cases though, a black pixel could be stuck, not necessarily dead. The main distinction is that a stuck pixel is permanently on, while a dead pixel just won’t turn on anymore. Unlike dead pixels, which are rarely resurrected, stuck pixels are just stubborn, and can respond to different remedies.
If what you see is a white or colored pixel, try some of the methods listed below to fix it.
How To Fix a Stuck Pixel On Your Monitor
1. Wait it out.
2. Perform a dead pixel test or check.
3. Use pressure and heat.
4. Use third-party software to flash the pixel.
5. Replace your monitor.
It’s easier to fix a stuck pixel compared to a dead one because it still has power supply, and you can reset it back to normal. Not all methods are guaranteed to work though, because ultimately it depends on what’s wrong with the pixel.
If none of these work, the last resort is to replace your monitor.
Wait It out
Stuck pixels can unstick themselves after a few hours. Some can take days or weeks, sometimes years, but you’re not going to wait that long for it to sort itself out.
If you don’t have the patience to wait, try the other methods below.
Run a Dead Pixel Test
A dead pixel test involves running your monitor in full-screen mode through a palette of basic colors or black and white to identify the stuck pixel.
To do this, clean your screen with a soft cloth, and then open the Dead Pixels Test site on your browser. Switch to full screen mode to look carefully at all test screens.
Use Pressure & Heat
These are manual methods of resolving stuck pixels by combining pressure and heat.
Before you start, turn off your monitor, and using a damp cloth, apply pressure to the spot where the stuck pixel is, without affecting other areas as this may create more stuck pixels.
As you apply the pressure, power on the computer and your screen, remove the pressure, and then check if the stuck pixel disappears. Usually, the liquid in one or more of its sub-pixels will pass through to create the different colors and spread equally.
The heat method involves placing a warmed cloth against the stuck pixel for a few seconds, and then turning the monitor off for up to 48 hours to allow the pixel drain excess power and go off.
Use Third-Party Software To Flash The Pixel
Stuck pixels are hardware problems, but you can get a software program that can act as a dead pixel fixer to unstick the pixel.
You can run the stuck pixel and others around it, through the software, cycling through various colors on your screen. The program will constantly ask the pixel to change its colors.
There are several options available but you can try using software such as JScreenFix, PixelHealer, or UndeadPixel to unstick the pixel.
JScreenFix can help you fix a stuck pixel but doesn’t help you find it. To use the software, open the site on your browser, and click the blue Launch JScreenFix. It’ll load a black browser window with a square that has many flashing pixels.
You can launch the window in full-screen mode by pressing the green button on the lower right side of your screen, and drag the square to the area where the stuck pixel is and let it stay there for 10 minutes.
UndeadPixel is a Windows dead pixel test tool that can help you find a stuck pixel using its locator, which cycles several colors across your screen. A flashing dot will appear, which you can drag and drop on your screen over the dead pixel and allow it to run for some hours.
You can also run an online monitor test to identify stuck pixels while testing the quality of your monitor. This test offers three modes through which you can test your screen for stuck pixels.
Replace Your Monitor
This is a last resort solution to fix a stuck pixel, if you really must. Most manufacturers offer warranties for repairs or replacement, so check your device’s warranty before taking this measure.
