arduino tft display brightness supplier

In electronics world today, Arduino is an open-source hardware and software company, project and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices. Arduino board designs use a variety of microprocessors and controllers. The boards are equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards (‘shields’) or breadboards (for prototyping) and other circuits.

The boards feature serial communications interfaces, including Universal Serial Bus (USB) on some models, which are also used for loading programs. The microcontrollers can be programmed using the C and C++ programming languages, using a standard API which is also known as the “Arduino language”. In addition to using traditional compiler toolchains, the Arduino project provides an integrated development environment (IDE) and a command line tool developed in Go. It aims to provide a low-cost and easy way for hobbyist and professionals to create devices that interact with their environment using sensors and actuators. Common examples of such devices intended for beginner hobbyists include simple robots, thermostats and motion detectors.

In order to follow the market tread, Orient Display engineers have developed several Arduino TFT LCD displays and Arduino OLED displays which are favored by hobbyists and professionals.

Although Orient Display provides many standard small size OLED, TN and IPS Arduino TFT displays, custom made solutions are provided with larger size displays or even with capacitive touch panel.

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 can also convert any interfaces to the customer’s requirements among the above interfaces or to higher level interfaces.

Genetic (Raw) Interfaces: Those are the interfaces which display or touch controller manufacturers provide, including 6800,8080, 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. They are widely accepted in the market. More information can be found on our other product pages. TFT modules, Arduino TFT display, Raspberry Pi TFT display, Control Board.

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 which make them be visible under all environments including direct sunlight. With proper adding 3M 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 which makes great contrast under direct sunlight. Orient Display has a special thermal management design to reduce the heat release and largely extend LED lifetime 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 fullcustomized 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.

Even if this is true, there are still ST7282 registers that users might want to change. For example, on pages 39-40 of the datasheet, I see registers for setting brightness, contrast, and gamma. These will not be accessible.

Is there a demo of this display to prove that it actually works? Because leaving out the serial interface seems like it might have been a mistake made by the designers. I just want to make sure that this module actually functions.

Tracing the circuit board, it appears that BL goes to a transistor (via 1k resistor), to switch 5V into the backlight, allowing an arduino to easily PWM higher currents than 40ma to the backlight.

Now, the strange thing is, the connection from the transistor to the backlight goes through a 330 ohm resistor (measures 329). At 5V, that means a max of 15ma to the backlight, which seems small (my Hitachi LCD draws 150ma). And if you"re going to restrict the amperage to 15ma, why bother putting a transistor in there at all, the arduino could easily provide that amperage on an output pin without a transistor boost.

(There"s also a solder-pad jumper allowing you to bypass the transistor, putting the 5V to the 330ohm backlight resistor. I"m guessing that won"t help, since low amperate is likely my problem to start with? I might try another resistor in parallel with the 330ohm one, to see if it boosts the brightness. Awkward in my current setup, but I gotta try something.)

With the growing popularity of easy-to-use hardware such as the Arduino1 or Raspberry Pi2, it is easier to build systems. In this application note, a simple display project is shown wherein the backlight is dimmed from 100% to 0%. It features the C164AXBSYLY6WT character display module (datasheet):

3.bWire up the circuit as shown in the following schematic (Figure 3). It should look similar to Figure 4. Note that Arduino pins 4 to 9 are digital I/O pins. Arduino boards also have analog I/O pins. Connect the Arduino to a PC via the USB cable.

The LCD is powered from the Arduino (+5V) through its USB port. LCD contrast is varied via potentiometer R1 through pin VO. Reset (RS), Enable (E), DB4 to DB7 is controlled via the sketch. While R/W is grounded (logic LOW); this means that the program is writing to the LCD register. If it is a logic HIGH, then it is reading from the LCD register. LED+ is connected to pin 10 of the Arduino which functions as a PWM.

The programming language used in the Arduino IDE is a derivative of C and C++ programming languages. At the heart of this sketch is LiquidCrystal library which is installed by default with the IDE. It is based on the HDD44780 LCD driver and is compatible with ST7066U.

3.dSpecify Arduino UNO is used and select the correct PC COM port. In the IDE top menu, select Tools > “Board: Arduino / Genuino UNO”. Then again, Tools > Port.

The brightness is controlled by line 55 of the sketch. There are 256 levels of brightness corresponding to the PWM duty cycle (0-100%). 0% or 0 means no backlight while 100% or 255 is full backlight.

In this example, we initially print some text to the LCD (lines 39-46). The brightness is first set to 100% (i.e. 255). Then decrement in 10% (i.e. 25.5) steps with a delay of 3 seconds between each step so you can see the effect (line 56-59).

It is worth noting that Arduino PWMs typically have a frequency of 490 Hz which is more than enough to prevent flicker. The suggested range is 60 to 250Hz. There is an available library where the frequency can be controlled (downloadhere).

Lastly, pay attention to the initialization of the LCD library specifically the wiring of the Arduino pin with the corresponding LCD pin. Incorrect declaration of the pins may result in a malfunction. If RS is connected to 9 and EN is connected to pin 8 of the Arduino, the initialization is:

1Arduino is an open-source development platform for easily building electronics projects that can electrically sense and control other objects. Arduino boards are primarily based on the Atmel AVR (8-bit) microcontroller (Example: Arduino UNO).

2The Raspberry Pi is a single-board computer. It features the Broadcom SOC (System-on-Chip) which includes a CPU and a GPU. Similar to the Arduino, it can be used for electronics projects (professional or hobbyist).
