Electronic device

An electronic device, comprising:

• a backlight module configured to emit a backlight;
• a display module disposed on a light-emitting side of the backlight module and configured to emit a display light based on the backlight, the display module including:
• a first substrate;
• and
• a semiconductor structure array and a pixel structure array disposed on a side of the first substrate facing away from the backlight module, the semiconductor structure array being disposed between the first substrate and the pixel structure array and including:
• a first semiconductor structure array configured to control pixel structures in the pixel structure array to convert the backlight into the display light;
• and
• a second semiconductor structure array configured to function as a photosensitive component to detect the backlight and generate a current representing a backlight intensity based on light irradiation from the backlight;
• and
• a light guide structure including:
• a first end facing the backlight module;
• a second end facing the second semiconductor structure array;
• wherein the light guide structure is configured to collect the backlight at the first end, guide the collected backlight along a light transmittance path defined by the light guide structure, and emit the guided backlight from the second end to the second semiconductor structure array.
