Display initialization is the set of procedures executed after power-on, necessary for the proper operation of the display. It includes configuring the display controller and sending initialization commands that define image parameters such as resolution, orientation, transmission mode (RGB, LVDS, MIPI DSI), signal timing, gamma, brightness and voltages. This process requires the correct sequence of actions, including powering the panel, turning on the backlight, and starting data transmission.
The sequence may be implemented in hardware (e.g. by a microcontroller) or in software, depending on the system design. Incorrect initialization leads to no image, interference, color errors or improper touch operation. A correct startup sequence is crucial for system stability and reliability.
