The Capacitive touch panel is activated with anything containing an inductive load such as a finger or stylus. It allows for multi-touch options. When using the capacitive touch screen, the display needs a separate controller to interface with the touch panel. The display for capacitive touch is brighter since the touch panel is transparent.

The Transmissive polarizer is best used for displays that run with the backlight on all the time. This polarizer provides the brightest backlight possible. If you have a need for a bright backlight with lower power drain, transmissive is a good choice for this TFT LCD display.

Well, I really want to like it. One thing I can definitely say for it is that the resolution and clarity of the screen is excellent. Oddly, the color/brightness settings are weird though. To get it about where an decent screen should be, I had to set brightness all the way down to 33 and both contrast and saturation had to actually go way up to 75 or so. (I don"t really have a calibration guide handy, so this was eyeballing it.) Note that this has no backlight adjustment -- this is a software brightness setting that barely changes it by a lot (so mostly a higher setting just washes things out.) Contrast almost seems to adjust sharpness more than actual contrast as well, which is strange, so it needs to be higher but does worse if you go too high. When you set things connected to it to produce 1024x600 resolution the clarity with these settings is beyond amazing for such a tiny screen though. Even at a HDMI default of 720p it"s actually pretty good. It also seems to be _VERY_ tolerant of outside resolutions. I accidentally typed 1024x700 and it took me a while to figure out what was wrong because it not only accepted the resolution, but resized it very well and it was still very clear. That"s a pretty huge plus right there and would have been worthy of at least four stars. If it wasn"t for the viewing angle...

Unfortunately, this is where it loses significant points. If I were rating it on viewing angle alone it would get one star even. I"ve never seen a screen this bad in that respect and I have used laptops in the MS-DOS days when LCD latencies were practically measured in seconds rather than milliseconds (pro-tip, NEVER play Descent on a laptop with really really high LCD latency. You WILL be sick.) Left and right viewing angle are great -- which is ironic because in most applications for this thing left and right aren"t that big of an issue -- but the up and down viewing angle literally couldn"t be any worse. Specifically, you can NOT look at this thing directly straight on. It MUST tilt up away from you so you"re basically looking up at it somewhat. I would estimate it has to go about 25-30 degrees or so off from being parallel. That"s pretty extreme to the point of being a bit ridiculous. The stand doesn"t do high precision either on the tilt, so you won"t really get it at quite an optimal angle and just have to get it as close as you can (about 35 or so I guess is what it works out to if you get it on the closest catch and then tilt it just a bit.) If you get at all close to looking at it parallel it turns insanely dark and you can"t see details or color well at all -- even text is insanely hard to read. As you approach 90 degrees, it starts to invert before you even actually get to a straight head-on look at it. Any higher and it outright inverts. If you can tilt it just right, the colors are pretty close to an IPS panel almost even (a bit lacking compared to a real IPS, but better than most TFT panels.) But this unreasonable viewing angle is extremely offputting. Also, as a side effect, since it has to stay tilted upwards, this means it collects dust like there is no tomorrow. That"s even more offputting. If it didn"t have such good visual clarity and color production I"d have to give it only one star even. Unfortunately, no matter how you position it, it will never be QUITE right with colors a bit more washed than they should be at one angle and too dark to even see at another. If you"re buying this just to act as a camera monitor or a simple screen for a server or something it will work great, but if you buy it for handling something like an OpenElec system, you"ll probably be very unhappy with the ridiculous viewing angle.

(hdmi_drive may not be needed. I had a typo in mine and only noticed when I was copying and pasting here, so all this time it was not using it, but it was definitely going to 1024x600 in everything as verified both via software and the screen itself. It is hdmi_group and hdmi_mode that forces it to use the custom resolution defined by hdmi_cvt.)

In this Arduino touch screen tutorial we will learn how to use TFT LCD Touch Screen with Arduino. You can watch the following video or read the written tutorial below.

For this tutorial I composed three examples. The first example is distance measurement using ultrasonic sensor. The output from the sensor, or the distance is printed on the screen and using the touch screen we can select the units, either centimeters or inches.

The third example is a game. Actually it’s a replica of the popular Flappy Bird game for smartphones. We can play the game using the push button or even using the touch screen itself.

As an example I am using a 3.2” TFT Touch Screen in a combination with a TFT LCD Arduino Mega Shield. We need a shield because the TFT Touch screen works at 3.3V and the Arduino Mega outputs are 5 V. For the first example I have the HC-SR04 ultrasonic sensor, then for the second example an RGB LED with three resistors and a push button for the game example. Also I had to make a custom made pin header like this, by soldering pin headers and bend on of them so I could insert them in between the Arduino Board and the TFT Shield.

Here’s the circuit schematic. We will use the GND pin, the digital pins from 8 to 13, as well as the pin number 14. As the 5V pins are already used by the TFT Screen I will use the pin number 13 as VCC, by setting it right away high in the setup section of code.

I will use the UTFT and URTouch libraries made by Henning Karlsen. Here I would like to say thanks to him for the incredible work he has done. The libraries enable really easy use of the TFT Screens, and they work with many different TFT screens sizes, shields and controllers. You can download these libraries from his website, RinkyDinkElectronics.com and also find a lot of demo examples and detailed documentation of how to use them.

After we include the libraries we need to create UTFT and URTouch objects. The parameters of these objects depends on the model of the TFT Screen and Shield and these details can be also found in the documentation of the libraries.

Next we need to define the fonts that are coming with the libraries and also define some variables needed for the program. In the setup section we need to initiate the screen and the touch, define the pin modes for the connected sensor, the led and the button, and initially call the drawHomeSreen() custom function, which will draw the home screen of the program.

So now I will explain how we can make the home screen of the program. With the setBackColor() function we need to set the background color of the text, black one in our case. Then we need to set the color to white, set the big font and using the print() function, we will print the string “Arduino TFT Tutorial” at the center of the screen and 10 pixels  down the Y – Axis of the screen. Next we will set the color to red and draw the red line below the text. After that we need to set the color back to white, and print the two other strings, “by HowToMechatronics.com” using the small font and “Select Example” using the big font.

Now we need to make the buttons functional so that when we press them they would send us to the appropriate example. In the setup section we set the character ‘0’ to the currentPage variable, which will indicate that we are at the home screen. So if that’s true, and if we press on the screen this if statement would become true and using these lines here we will get the X and Y coordinates where the screen has been pressed. If that’s the area that covers the first button we will call the drawDistanceSensor() custom function which will activate the distance sensor example. Also we will set the character ‘1’ to the variable currentPage which will indicate that we are at the first example. The drawFrame() custom function is used for highlighting the button when it’s pressed. The same procedure goes for the two other buttons.

So the drawDistanceSensor() custom function needs to be called only once when the button is pressed in order to draw all the graphics of this example in similar way as we described for the home screen. However, the getDistance() custom function needs to be called repeatedly in order to print the latest results of the distance measured by the sensor.

Here’s that function which uses the ultrasonic sensor to calculate the distance and print the values with SevenSegNum font in green color, either in centimeters or inches. If you need more details how the ultrasonic sensor works you can check my particular tutorialfor that. Back in the loop section we can see what happens when we press the select unit buttons as well as the back button.

Ok next is the RGB LED Control example. If we press the second button, the drawLedControl() custom function will be called only once for drawing the graphic of that example and the setLedColor() custom function will be repeatedly called. In this function we use the touch screen to set the values of the 3 sliders from 0 to 255. With the if statements we confine the area of each slider and get the X value of the slider. So the values of the X coordinate of each slider are from 38 to 310 pixels and we need to map these values into values from 0 to 255 which will be used as a PWM signal for lighting up the LED. If you need more details how the RGB LED works you can check my particular tutorialfor that. The rest of the code in this custom function is for drawing the sliders. Back in the loop section we only have the back button which also turns off the LED when pressed.

This TFT display module comprises a 7" TFT with capacitive touch and an EVE accelerator PCB. The EVE accelerator PCB simplifies interfacing with the display as it makes the display, touch, backlight, and any added audio features appear to the host MCU as a memory-mapped SPI device. The host controller can send high-level commands to the EVE chip to quickly and easily describe images, text, buttons, tables, and more.

At 7" on the diagonal, this display offers plenty of space, making it a great choice for an information panel, menu, etc. Plus, thanks to the extremely wide viewing angle achieved using in-plane switching (IPS), this display can be read equally well above or below eye level.
