We used BK7258 to design another PCB that supports RGB+SPI+TP and RGB interface displays, which can support displays of a wide range of sizes and resolutions. This PCB removes the 4G module. We marked the list of supported displays on the back of the PCB.

We chose a 5" 800x480 reflective display as an application with a separate Goodix capacitive touch screen. There is no need to turn on the backlight in the sun, which can save a lot of energy and extend the battery life.

We tested this display on the T113 EVK as shown in the following figure:
