For the interfacing there is a main focus on both TFT displays and touchscreens. Most TFT displays are used in a system that has some sort of CPU (either ARM or Intel based). When the host (main board) has no direct display driving capabilities but is fitted with the more common VGA / DVI or HDMI port, DISvue has a total package of interface boards.
The display interface boards are available with straight forward conversion from e.g. VGA to LVDS or for example from HDMI to eDP. The boards can be more special for high resolution screens up to 4K and even 8K displays and multi-output for dual or other multiple screen control.
Under the DISvue brand label we have a number of factories that have developed their own interface boards that fit behind the display. This may be a microprocessor solution or a direct plug & play HDMI interface with touch interface option.
For touchscreens interface boards may be necessary. Not all touchscreens (especially larger ones) come with COF (controller on flex) and some need a special interface in order to be operational under more challenging conditions. Touch controller boards can be beneficial when:
- The size of the screen is too large to be operated directly via one controller chip;
- The touchscreen is used behind a thick frontglass (e.g. more than 5mm thickness);
- The touchscreen is used with worker gloves or
- It is operated in wet conditions (like outdoor or maritime applications).
One of the most trusted brands for both resistive touch controllers as well as capacitive touch controllers is EETI. This Taiwan based electronics company has a long and trustworthy reputation in both the hardware (controller ICs) and with the software (drivers). They also have a long history of fine tuning their controllers and support custom design on a daily basis.
