More Information
Summary:A LED pixel unit, a display panel and a display screen are provided. The LED pixel unit includes: multiple micro-LEDs with different emission wavelengths and an optical module, the micro-LEDs are stacked to form a stacked structure, the stacked structure has a light-emitting surface, and the stacked structure is configured to emit, from the light-emitting surface, light emitted by the micro-LEDs at a first emission angle; the optical module is disposed above the light-emitting surface and at a predetermined distance from the light-emitting surface, and the optical module is configured to emit, at a second emission angle, the light emitted by the light-emitting surface. The light emitted by the micro-LEDs in the same pixel unit is all emitted from the same light-emitting surface, incident on the optical module at the same angle, and emitted from the optical module at the same angle, so that a dispersion phenomenon can be avoided.
