Small displaysThe standard VM2 embedded controller can drive many, generally smaller, displays including alphanumeric and graphic, both colour and mono.
Because there are very many small graphic displays, and they all tend to be different, we don't supply small displays or provide hardware interfaces. Please contact us to discuss your application.
Larger displaysThe VM2D has a built-in display driver chip compatible with a range of colour displays of different sizes and resolutions up to WVGA (800x480) and up to 16 bit colour.
Library codeAll graphic displays are supported by a GUI Library that enables rapid development of graphical user interfaces.
Hitachi QVGA Colour Display with Touch ScreenWe stock a Hitachi TFT QVGA 16 bit colour display module with integrated touch screen, as supplied with Starter Kit 2. If you need to use a different display please contact us with your requirements.
- Hitachi TX14D16VM1CPC
- Active matrix TFT colour display.
- QVGA (320 x 240) resolution
- 18 bit colour (16 bits when used with VM2D)
- LED backlight
- touch screen
- Display area 115.2(W) mm x 86.4(H) mm
- Module dimensions 131.0(W) mm x 102.2(H) mm x (12.4)(D) mm typ.
This adapter PCB provides both a mechanical and an electrical interface between the Hitachi TX14D16VM1CPC display (described above) and our Application Board 2, which must be fitted with a VM2D controller.
It produces a neat mechanical assembly and provides correct signalling and power for the display, touch screen and dimmable backlight. It is supplied with mounting pillars, screws and ribbon cables.
This adapter normally requires that the host Application Board is supplied with 12VDC, though it can be adapted for other voltages. Please Contact us for supply of a 24VDC version (15V-34V).
Custom application boards would not need to use this adapter as they would carry the necessary circuits and connectors.
The picture shows how the Display, Display Adapter and Application Board screw together to make a single assembly.
During development the assembly can be opened out so the top sides of the Application Board and the Display are both accessible at the same time.
It is possible to rotate the displayed image 180° in software so you can mount the assembly either way up.
In future it will be possible to rotate the display by 90° or 270° to use it in portrait mode, but in all cases note that most LCD display hardware is designed to be viewed best from a particular angle.
