Colour TFT (Thin Film Transistor) displays are everywhere. From our beloved phones and wearables to billboards, dashboards, medical equipment and even coffee machines. TFTs are essential to the clear and high-resolution view you expect of any digital display. But as these examples show, the places and spaces in which you might find one vary greatly, and each respective application will have a slightly different operational requirement from its TFT.
Like all design, when it comes to building a display into your product, it’s generally a matter of balancing the right price with the desired outcome. In the vast majority of cases, you’ll be looking to get the maximum product performance from a fixed budget and that might mean that instead of an expensive custom solution, a slight modification to an existing product is a more than acceptable alternative. For example, a standard display, such as a touch monitor, will have a housing that generally comprises of its front bezel, a TFT cell with electronics and a backlight system. All these elements can be scaled up or down, depending on the size of the display. But what if you need to operate it across different temperature ranges? Or in spaces of differing levels of brightness? Or both?
