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.

The driver used in this LCD is GC9A01, with a resolution of 240RGB×240 dots and 129600 bytes of GRAM inside. This LCD supports 12-bits/16-bits/18-bits data bus by MCU interface, which are RGB444, RGB565, RGB666.

For most LCD controllers, the communication method of the controller can be configured, they are usually using 8080 parallel interface, 3-line SPI, 4-line SPI, and other communication methods. This LCD uses a 4-line SPI interface for reducing GPIO and fast speed.LCD

If you are wondering which point is the first pixel of the screen (because the screen is round), you can understand it as a square screen with an inscribed circle drawn in it, and it only displays the content in this inscribed circle. The pixels in other locations are simply discarded (just like most round smartwatches on the market)

TFTsMidas Displays offer a broad range of Thin Film Transistor (TFT) LCD panels in sizes ranging from 0.96" to 61". We are also able to offer other sizes and options to meet your specific requirements. Orientation includes landscape or portrait versions. Touch screens are optional and are available in resistive and capacitive technologies, with multi touch options if required. To meet the demands of customer applications these displays are available with viewing angles of 6 and 12 o"clock, or all round view utilising ARVA film or IPS technology.
