Orient Display sunlight readable TFT displays can be categorized into high brightness TFT displays, high contrast IPS displays, transflective TFT displays, Blanview TFT displays etc.

The brightness of our standard high brightness TFT displays can be from 700 to 1000 nits. With proper adding brightness enhancement film (BEF) and double brightness enhancement film (DBEF) and adjustment of the LED chips, Orient Display high brightness TFT products can achieve 1,500 to 2,000 nits or even higher luminance. Orient Display have special thermal management design to reduce the heat release and largely extend LED life time and reduce energy consumption.

Our high contrast and wide viewing angle IPS displays can achieve contrast ratio higher than 1000:1 which can make readability under strong sunlight with lower backlight luminance. High brightness IPS displays have been widely accepted by our customers with its superb display quality and it has become one of the best sellers in all our display category.Transflective display is an old monochrome display technology but it has been utilized in our color TFT line for sunlight readable application. Orient Display has 2.4” and 3.5” to choose from.

Blanview TFT displays are the new technology developed by Ortustech in Japan. It can provide around 40% of energy consumption for TFT panels which can use smaller rechargeable or disposable batteries and generate less heat. The price is also lower than traditional transflective TFT displays. Orient Display is partnering with the technology inventor to provide 4.3” and 5.0”.

Orient Display can also provide full customized or part customized solutions for our customers to enhance the viewing experience. Orient Display can provide all the different kinds of surface treatments, such as AR (Anti-reflection); AG (Anti-glare), AF (Anti-finger print or Anti-smudge); AS (Anti-smashing); AM (Anti-microbial) etc. Orient Display can also provide both dry bonding (OCA, Optical Clear Adhesive), or wet bonding (OCR, Optical Clear Resin and OCG, Optical Clear Glue) to get rid of light reflective in air bonding products to make the products much more readable under sunlight and be more robust.

Touch panels have been a much better human machine interface which become widely popular. Orient Display has been investing heavy for capacitive touch screen sensor manufacturing capacity. Now, Orient Display factory is No.1 in the world for automotive capacitive touch screen which took around 18% market share in the world automotive market.

Based on the above three types of touch panel technology, Orient Display can also add different kinds of features like different material glove touch, water environment touch, salt water environment touch, hover touch, 3D (force) touch, haptic touch etc. Orient Display can also provide from very low cost fixed area button touch, single (one) finger touch, double finger (one finger+ one gesture) touch, 5 finger touch, 10 points touch or even 16 points touch.

Considering the different shapes of the touch surface requirements, Orient Display can produce different shapes of 2D touch panel (rectangle, round, octagon etc.), or 2.5D touch screen (round edge and flat surface) or 3D (totally curved surface) touch panel.

Considering different strength requirements, Orient Display can provide low cost chemical tampered soda-lime glass, Asahi (AGC) Dragontrail glass and Corning high end Gorilla glass. With different thickness requirement, Orient Display can provide the thinnest 0.5mm OGS touch panel, to thickness more than 10mm tempered glass to prevent vandalizing, or different kinds of plastic touch panel to provide glass piece free (fear) or flexible substrates need.

Of course, Orient Display can also offer traditional RTP (Resistive Touch Panel) of 4-wire, 5-wire, 8-wire through our partners, which Orient Display can do integration to resistive touch screen displays.

Engineers are always looking for lower cost, faster, more convenient interfaces to transmit signals and to accept data and commands. The numbers of available interfaces available in the market can be dazzling. Orient Display follows market trends to produce various kind of interfaces for our customers to choose.

Genetic Interfaces: Those are the interfaces which display or touch controller manufacturers provide, including parallel, MCU, SPI(,Serial Peripheral Interface), I2C, RGB (Red Green Blue), MIPI (Mobile Industry Processor Interface), LVDS (Low-Voltage Differential Signaling), eDP ( Embedded DisplayPort) etc. Orient Display has technologies to make the above interface exchangeable.

High Level Interfaces: Orient Display has technologies to make more advanced interfaces which are more convenient to non-display engineers, such as RS232, RS485, USB, VGA, HDMI etc. more information can be found in our serious products. TFT modules, Arduino TFT display, Raspberry Pi TFT display, Control Board.

TFT Displays provide rich colors, detailed images, and bright graphics with their full-color RGB mode. TFT displays are perfect for applications including industrial instruments, coffee machines, automation, GPS navigator, energy control, and medical devices.

This project involves yet another Arduino-compatible display which can be used as an output to display any information in the form of graphics, text or animations. Since this is a 1.3" 240x240 IPS (In-Plane Switching) TFT display module, it does offer a high-resolution colour display with fine graphics, and that is one of the things which I really enjoy about this display. It is also very easy to program, as it runs on the STT789 display, which is helpful to know, as the Adafruit ST7789 library supports this display, and is what we will be using today. The code used below is a fairly complex code at first, which showcases this display"s capabilities and what it can do, in terms of functionality. For the wiring, a 6-pin wiring configuration is used with the SPI interface to the Arduino, which will be shown below. Finally, for this project, here are the components which you will need:1 1.3" 240x240 IPS TFT Display Module

This project is fairly​ straightforward to set up so make sure you start by unplugging any power source feeding into your Arduino to prevent any shorts while wiring. Firstly, take a jumper wire and connect the GND pin on the display to any of your Arduino"s GND pins and follow that up by connecting the VCC pin from the display to the 3v3 pin of your Arduino to supply a +3.3 volt power supply to the module. +5v will have a possibility to damage the display. Now, for the i2c connections, hook up the SCL (Serial Clock) pin of the display to A13 (analog pin 13) on the Arduino and the SDA (Serial Data) pin to A11 (analog pin 11). For the RES (Reset) pin, connect it up to A8 (analog pin 8) as well as the DC (Data/Command) pin to A9 (analog pin 9). The hardware part is finally done!

This code may seem slightly intimidating at first, due to its length and much newer functions, but once it is broken down, it isn"t so hard anymore. In the first three lines, we declare libraries for running this display, the graphics used, and for the interface used, which is the SPI interface. In the next three lines, the RST (Reset) and DC (Data/Command) pins are defined, which are connected to A8 (analog pin 8) and A9 (analog pin 9). In the next line, we initialize the Adafruit ST7789 library for use with this display and we follow that by defining the value of pi as a float variable in that next line. We will be using this float variable later on for graphics and calculations needed. Thevoid setupsection is now here where we first start by begining serial communication with a baud rate of 9600 bauds and printing a test message which is "Hello! ST7789 TFT Test!". In regards to the display, we address that our display module is of 240x240 resolution and we set the rotation of our display in the next line. If your display is flipped, removetft.setRotation(2)​. From there, we print the text "Initialized" as our display is now correctly set up. After that, we count up the seconds from the startup with themillis()function and store it in an unsigned 16-bit integer, namedtime, for use later. We then fill up the TFT screen with a black colour. Since we already started the stopwatch which counts up, we can always reset the stopwatch back to zero by using subtracting thetimefunction with themillis()​.To end off this section, we set a delay for 500 milliseconds before moving on. This section onwards will only be for the animations, graphics and images displayed on the screen, and we start off by filling the screen with a black background and writing some text with a white colour before a 1-second delay. Proceeding that, we execute a print test which basically is already programmed to print out a set of text in different font colours and sizes. We end this test by setting a delay for 4 seconds. From this point, the rest of the code is responsible for printing out the different graphics, which can be composed of shapes, pixels and text. All the different graphics and its individual code are mentioned at the end of the code so I recommend really going through this program to learn all the commands, which can help you build your own demo code, even with your own personal images being displayed. This project is now done!

The BasicTest.ino code shows us the basic display functions of the screen: text display, number display, drawing lines, drawing rectangles and other demos.

A number of display devices like LEDs, 7-segments, character and graphic displays can be attached to microcontrollers to create an interface between the user and an electronic system for displaying data or controlling the system. Sometimes you may need to add colorful images or graphics to your project, that’s where the TFT color displays come in handy.

TFT LCD is a variant of a liquid-crystal display (LCD) that uses thin-film-transistor (TFT) technology to improve image qualities such as addressability and contrast. In this tutorial we are going to show how to interface a 1.44″ TFT color display based on the ST7735 driver. It has 128×128 color pixels and can display full 16-bit color.

This is the type of display am using but they come with various pin configurations. However all the displays will have the major pins stated below and should be connected to the Arduino board as follows:

This TFT display uses 3.3V but comes with an on board voltage regulator therefore the VCC can be connected to the Arduino 5V. However for best practice it’s better to use the 3.3V.

Most code Libraries for this TFT ST7735 display with Arduino are programmed with the SDA and SCL pins connected to Arduino pins 11 and 13 respectively. Make sure you don’t change that order otherwise the display may not work.

There are a number of libraries that have been developed to run the TFT ST7735 color display using Arduino but I found the Adafruit-ST7735-Librarythe best to use. Make sure you have this library installed in your IDE.

tft.fillRoundRect(x,y,w,h,r,t); function draws a filled Rectangle with r radius round corners in x and y location and w width and h height and t color.

There are many other functions and commands which you can use to program the TFT color display but the above are the commonest. You will meet many more with practice.

Before we can write our personal code we need to first test the display using the already made code examples from the installed library. This is done by going to File>Examples>Adafruit ST7735 and ST7789 Library. Then you can select any of the examples and upload it to the setup to see if the display works fine.In the diagram below I have shown how to access the graphics test code.

The purpose of this guide is to get your 0.96″ color LCD display successfully operating with your Arduino, so you can move forward and experiment and explore further types of operation with the display. This includes installing the Arduino library, making a succesful board connection and running a demonstration sketch.

Although you can use the display with an Arduino Uno or other boad with an ATmega328-series microcontroller – this isn’t recommended for especially large projects. The library eats up a fair amount of flash memory – around 60% in most cases.

(As the display uses the ST7735S controller IC, you may be tempted to use the default TFT library included with the Arduino IDE – however it isn’t that reliable. Instead, please follow the instructions below).

Please check that the library has been installed – to do this, select the Sketch > Include Libraryoption in the IDE and scroll down the long menu until you see “ER-TFTM0.96-1” as shown below:

The display uses the SPI data bus for communication, and is a 3.3V board. You can use it with an Arduino or other 5V board as the logic is tolerant of higher voltages.

The library used is based on the uTFT library by Henning Karlsen. You can find all the drawing and other commands in the user manual – so download the pdf and enjoy creating interesting displays.

TFT displays are full color LCDs providing bright, vivid colors with the ability to show quick animations, complex graphics, and custom fonts with different touchscreen options. Available in industry standard sizes and resolutions. These displays come as standard, premium MVA, sunlight readable, or IPS display types with a variety of interface options including HDMI, SPI and LVDS. Our line of TFT modules include a custom PCB that support HDMI interface, audio support or HMI solutions with on-board FTDI Embedded Video Engine (EVE2).

In Part 1, we were able to obtain and display values from KX022-1020 accelerometer on the TFT LCD panel. In Part 2, we’ll show how to control the TFT monitor while reading the contents of the program!

As before, we’ll be usingSainSmart ST7735RTFT monitor. It’s a compact LCD display that can be used both with Arduino and Raspberry Pi. The monitor has a built-in microSD card slot, so it’s possible to store and load images, in addition to reading and writing data. In this tutorial, we will only try to display values on the TFT monitor.

Once you made the change, compile the unzipped “TFT 18” directory with zip again, add it as a library in Arduino (or Arduino Create) Add Library, or place it under the “libraries” directory in Arduino’s installed directory and load the library.

for (uint16_t x=0; x < tft.width; x+=6) { tft.drawRect(tft.width/2 -x/2, tft.height/2 -x/2 , x, x, color); } } void testfillrects(uint16_t color1, uint16_t color2) { tft.fillScreen(BLACK); for (uint16_t x=tft.width-1; x > 6; x-=6) {

for(uint16_tx=0;x6;x-=6){

Next, let’s display the accelerometer values on the TFT monitor! In the case of the Sensor Evaluation Kit, basically, it’s not necessary to change the wiring on the TFT monitor side. All that is needed is to insert KX022-1020 accelerometer to the Sensor Shield.

for (uint16_t x=0; x < tft.width; x+=6) { tft.drawRect(tft.width/2 -x/2, tft.height/2 -x/2 , x, x, color); } } void testfillrects(uint16_t color1, uint16_t color2) { tft.fillScreen(BLACK); for (uint16_t x=tft.width-1; x > 6; x-=6) {

for(uint16_tx=0;x6;x-=6){

When it goes to the edge of the 120px display, the graph is cleared with drawrect. The numbers on the upper part are updated with drawrect for each frame in the same way.

This concludes the tutorial on how to display and graph accelerometer values using TFT LCD monitor! There are quite a few side projects we can consider developing. For example, we can combine this TFT monitor and Arduino Pro Mini to make a wristwatch featuring small games, etc. It is also possible to make a data logger using, for instance, different sensors from the Sensor Evaluation Kit.
