This article will take you through a high level overview of all of the parts of a TFT LCD display.  The vast majority of what I have read on the internet makes this whole issue massively complex.  I’m quite sure that this complexity problem is a real reflection of the serious design and manufacturing complexity in these displays and drivers.  That being said, to get a conceptual understanding is much simpler, and is the point of this article.

A significant amount of my learning about this subject came from a 195 page powerpoint presentation by Dr. Fang-Hsing Wang entitled “Flat Panel Display : Principle and Driving Circuit Design“.  He has graciously allowed me to reproduce a few of his images.  This dude knows way way more about these circuits than I do and I would encourage you to read his work.

The fundamental element in a TFT display is the liquid crystal.  These elements have the property that the crystals will align from horizontal (which blocks the light) to vertical (which lets most of the light through) based on the electric field applied to them.  Basically, you shine light through the liquid crystal, which blocks some or all of the light, the remainder of the white light then goes through a color filter to make red, green, or blue. It works like this:

This architecture means that every pixel in the display will require a red, green and blue element.  And, you will need to control the voltage on all of the elements (which will be quite a lot on a screen of any size)

What does the schematic for one element in a pixel look like?  And where is the T(transistor) in the TFT?  The three letter acronym TFT stands for a thin film transistor that is physically on the top of the LCD matrix right next to each liquid crystal element.  Here is a schematic model for one element in the array.  C-LC represents the capacitance of the liquid crystal.  CS is a storage capacitor that is used to hold the electric field across the liquid crystal when the transistor is OFF.   To apply a voltage across the LC you just turn on the gate and apply the correct voltage to the column commonly known as the source.

You should notice that the “back” terminal of the two capacitors is called “VCOM” and is physically on the other side of the liquid crystal matrix from the TFT.  All of the liquid crystal backsides in the display are connected to the same VCOM.  A bit of painfulness in this system is that the CS capacitor leaks, which means that the LCD changes state which means that each pixel must be updated, properly called refreshed, on a regular basis.

If you have been thinking about this system you might have done a little bit of math and figured out that you are going to need an absolute boatload of source and gate driver signals.  And you would be right!  For example, a 4.3″ screen with 480×272 will require 480x272x3 elements which are probably organized into 480 rows by 816 columns.  This would require a chip with at least 480+816=1296 pins, that is a lot.  It turns out that for small screens <=3.5″ there are chips with enough pins to do the job.  But, for larger screens, it requires multiple chips to do the job.  The “…” in the picture above shows the driver chips being cascaded.  The next thing to know is that “TFT Glass” usually has the driver chip(s) embedded into the screen at the edge (you can see that in the picture from Innolux above).

You must put a quite high voltage source >20v and drain <-10V across the liquid crystal at the right time to get it to do its thing.  In order to pass that source voltage, the gate must be turned on at the right time to the right voltage, this is the purpose of the Gate Driver IC.  The gate driver is conceptually simple and Dr. Wang drew a nice picture on page 7 of his presentation.  You can see that it is basically a shift register, with one element per gate.  You shift in a “1” and then clock it through the entire shift register which will have the effect of applying a 1 to each gate.

In its most basic form, the TFT source driver is responsible for taking an 8-bit digital input value representing the value of an individual LCD element and turning it into a voltage, the driving the voltage.  Like this:

In reality there is some compromise of chip size, number of pins and time that is made by multiplexing pins, columns and rows.  For example, many of the small screens appear to have 1 column driver for all of the reds, 1 driver for the blues and one for greens.

What appears to happen in real life on bigger screens is some combination of column and row multiplexing.  In one display that I found there were 2x the number of rows which allows the columns to be multiplexed 2-1.  The display is 1024×600.  That requires 1024*3 RGBs in the column = 1536 pins.  This means that you need to double the number of gate drivers, resulting in 1200 pins in the row direction.  Here is a picture from their datasheet.

The last issue that I will address in TFT LCD drivers is called Gamma Correction or more simply Gamma.  Gamma is an intensity adjustment factor.  For any given digital intensity input, you will need a non-linear translation to a voltage output on the source.  For example a doubling of digital input (so that a pixel appears twice as bright) you will not double but instead will have some non-linear translation of the output voltage.

The good news is that this gamma correction is built into the display drivers.  From my reading, this is sometimes done with digital processing, and sometimes done with an analog circuit.  But in general, it appears to be tuned and programmed into the driver by the panel vendor for these smaller display.

The graphics drivers are an integral part of your PC or laptop, ensuring you get the desired graphics displayed while gaming or doing other work. But, often, you are facing some issues related to the graphics. Sometimes your screen freezes in between gaming or starts to flicker. Some users have also reported that they experienced poor quality graphics during gaming, while others experienced sudden crashing of the game.

Usually, the graphics driver of your PC is equipped to troubleshoot such issues. It first displays an error message and then automatically restarts the graphics driver to solve the issue and displays the original graphics again.

If your PC does not reset the graphics drivers automatically, you will have to resort to a manual resetting procedure. Here you will get a detailed guide on the procedure.

The graphics driver is a software program that controls the whole aspect of the graphics set-up including the monitor, the software that displays graphics etc.

In other words, the graphics driver enables your computer to convert the binary codes into graphics, and your monitor displays the graphics to you. That means the Graphics driver directs the graphics card to complete its work properly. It is needed to display pictures, videos and even animated icons sometimes!

As you already understand, the graphics driver is the sole software that manages everything related to the display on your computer. If it malfunctions, the main effect will be poor-quality visual displays including-

A sudden black screen-If the graphics driver malfunctions, you may encounter a sudden black screen. Your computer screen may turn pitch black during a gaming session or while displaying videos or pictures.

App crashing-Another thing you may commonly experience after the graphics driver malfunctions is the app crash. It is also common for gaming apps and other apps that require visual elements to a large extent. The app may never open or can crash in between. In other words, the app may get closed automatically while it is open on your Often the games don’t start after your GPU becomes faulty.

Visual bugs-After the graphic driver malfunction, the computer also develops multiple visual buses. You may experience poor-quality visual graphics including mission icons or missing smaller visual elements. Sometimes, you can also experience visible screen tears or screen distortions while gaming or doing other words.

If your Graphics driver has crashed or is malfunctioning, it is time to reset it. Resetting will allow the GPU to get back to its clean state. While resetting, you delete the current GPU and reinstall it with a cleaner and more updated version that does not contain the bugs.

Sometimes, the GPU starts to malfunction due to the corrupted cache it develops. It may happen due to the extreme load that your device puts on the GPU during extension gaming sessions. In such cases, also resetting allows you to get a clean and more updated graphics driver that can work properly.

To reset the graphics driver, you need to press thewindows key, Ctrl, Shiftand Bkeys together. After a few seconds, your computer screen will start to flicker and may turn black for a few seconds before returning to its normal state.

Beside the file, click on “End Task,” which appears on the right side of the file. Repeat this for all the graphics card-related files (or files with the word Nvidia or AMD”. It will reset your drivers. Wait till your computer screen flickers for some time. After all the files are deleted the task is complete.

Now, right-click on a GPU file and select “Enable Driver” from the pop-up menu to enable it. Follow the same process if your computer has multiple Graphics Drivers.

Alternatively, visit the website of the graphics card manufacturer from your device. Now, download the graphics card driver software (applicable to your computer OS and model number).

An updated GPU– After resetting the graphics driver, it gets updated to the latest version, which is more advanced and capable. Hence, you can experience better visual elements without frequent crashes.

After resetting the GPU, you may find that other drivers have frozen. In this case, you may need to disable or enable those frozen drivers to ensure the device works smoothly again. Here is how to do this-

You have tried resetting the graphics driver, but nothing works. Your computer’s display driver has become corrupted, resulting in poor-quality graphics. In this case, resetting the GPU will not work as it cannot repair the display driver. So, the best way is to reset the display driver.

So, if you have tried resetting the graphics driver, but it does not work, check the windows update status again. Probably the OS needs some upgrades.

Why not try to update the GPU instead of resetting it? Probably the Driver is outdated and needs an update only to remove the bugs of the current update you have. To update, follow this procedure-

If you are experiencing a frozen screen or poor-quality graphics on your computer, the Graphics Driver is probably not working properly. In such a case, resetting the driver can help. You may use this article as a guide to solve the issue and get the best PC experience with optimal graphics.

If you’re suffering from software bugs or other problems with your graphics card, one of the first things to try is performing a clean installation of your drivers. That point was driven home for PC gamers this week when AMD, in a post announcing WHQL certification for its bug-squashing new Radeon Software Adrenalin 2020 Edition 20.2.2 driver, told gamers to factory reset the software if they encounter futher issues.

Modern graphics card drivers are complicated beasts, sinking hooks deep into your computer. Considering that both AMD and Nvidia’s drivers weigh in at roughly half a gigabyte, they’re some of the more complex software on your PC. They build atop your existing installation, and that’s generally a good thing! It keeps your existing settings intact. But express-installing drivers can cause issues sometimes. Performing a clean install starts over from scratch, potentially eradicating conflicts that can manifest as bugs or performance issues. I even do it every now and again on my personal rig, just for general system health.

“Often, many problems can be resolved with a clean installation of our driver,” AMD’s Warren Eng said in the company’s post. “In order to perform a clean installation, you must select the ‘Factory Reset’ option at the beginning of the installation process. Once this is selected, old instances of the driver will be removed, and the uninstaller will restart your system before the new driver installation begins.”

If you have a GeForce graphics card, resetting the drivers takes a slightly different (but still simple) process. Start the installation process, click Custom install, and make sure to check the “Perform a clean installation” box. From there, complete the task normally.

As Nvidia’s checkbox warns, performing a clean driver install blasts away your previous version of the software, which means that all settings will be returned to their default. The same goes for AMD’s clean installation process, which it dubs “Factory reset.” That could be a headache if you heavily customize your graphics card’s software, but worthwhile if you’re suffering from software issues. If you’ve tinkered extensively, you might want to jot down your altered settings beforeinitiating the process, so you can get everything back the way you want it more easily afterward.
