DISPLAY VISION's compact graphic display TFT015-22AI is bright and sharp, but economical in power consumption. Its IPS panel scores highly thanks to its all-round viewing angle and readability in sunlight.
The active area of the IPS colour display measures just 28 mm square. But despite this small size, the resolution of 240x240 pixels provides a detailed and crisp graphic display with 16 bit colour resolution. The maximum brightness of 1,100 cd/m² ensures a high-contrast display even under extreme light conditions, such as in bright sunlight or under operating room lamps. Unlike other LCD screens, the contrast of this IPS panel remains nearly the same even at very oblique viewing angles thanks to the AACS technology. The external installation dimensions are 32x35x3.2 mm.
The 16 bit RGB, 18 bit or 8 bit parallel and SPI interfaces are available for control. The supply voltage is 3.3 V. Due to the low current consumption, typically 20 to 80 mA, the compact colour displays are ideal for installation in battery-operated handheld devices. And this over a wide temperature range from -20 to 70 °C.
The coloured IPS panel is also available with a capacitive touch screen surface in the form of the TFT015-22AITC. At 44x46x3.5 mm, it is somewhat larger but its maximum brightness – 1,000 cd/m² – is only slightly lower. On the other hand, the glued touch screen surface protects it even better against external weather influences.
It is assembled by simply sticking it in place. For testing purposes or to quickly and easily connect to various microcontrollers, DISPLAY VISIONS also offers a test and adapter board with corresponding software for these displays (9782-1USB). TFT015-22AI and TFT015-22AITC are available in any amount from 1 piece upwards for immediate delivery. DISPLAY VISIONS guarantees availability for at least ten years.

Datasheet

With the EA DOG series, DISPLAY VISIONS has a range of flat, modern COG displays with an integrated driver. Modest power consumption and usable in 3.3 V systems, they are particularly suitable as displays in handheld devices.
The compact text and graphic LCDs are less than 3 mm thick. Designed as chip-on-glass displays, the controller is already integrated into these displays. The text displays come with built-in character sets. These high-contrast displays can be soldered directly onto the PCB. They run with 3.3 V without auxiliary voltage and the current consumption is between 150 and 900 µA depending on the model and size. They are controlled using a 3 or 4-wire SPI, or, for some models, even using a 2-wire I²C or 4 or 8-bit data bus.
The text and graphic displays are currently available in 13 different sizes, from 55x31 mm to 94x67 mm. This includes 6 text displays with one to four lines and 7 graphic displays with resolutions between 102x64 pixels to 240x128 pixels. There are five high-contrast LCDs to choose from: reflective and transmissive STN, STN with blue background and black/white positive and negative FSTN. The contrast voltage can be set by command. Graphic displays can also be rotated 180° for mechanical reasons or to make them easier to read, for example for installation in the front of a laboratory power supply unit. The EA DOG displays can also be combined with a touch screen.
For the backlight, the user has a choice of 6 colours. White, yellow/green, blue, amber, red and full-colour RGB. Simply place the backlight behind the display and solder it into the PCB with the display. No additional fastening is required. Operation of backlight is either via an external series resistor or an LED driver. Meaningful operation is possible from 3 mA.
All panel variants are available from just one piece. DISPLAY VISIONS GmbH guarantees long-term availability of up to 10 years. This also ensures replenishment for product lines designed to be long term.
A free simulator is available to download on the manufacturer’s website. It allows you to simulate all display versions and colours on your Windows PC before buying. A USB test board is also available for an easy start with a real display. This allows your own text to be shown on the connected display straight away. DISPLAY VISIONS also supports the developers with comprehensive support and extensive C and micro-controller code.

More about this display family...

From now on DISPLAY VISIONS is offering a USB demo board for IPS displays from 0.9" to 3.5".

With the EA 9782-1USB, DISPLAY VISIONS GmbH is providing developers with a USB test board for small IPS displays from the EA TFT product line. This allows the small panels, including the variants with touch function (-AITC), to be tested and adapted quickly and easily without any specific knowledge of the hardware or software. The demo board can be run immediately on any USB charger. Connected to a Windows PC and accessed via the startTFT.exe program, it opens up more options to display your own images or control the brightness. An additional power supply is not necessary in this case. A bundle including the display is also available.
