A projection apparatus, an illumination apparatus thereof, and a light source driving method thereof are provided. A control module converts a bit control signal into first light source timing signals, converts the first light source timing signals into second light source timing signals according to a lookup table, generates a driving current corresponding to each light source according to the lookup table, outputs second light source driving signals corresponding to the light sources according to the second light source timing signals. The lookup table includes a driving current ratio corresponding to the light sources. A driving module drives the light sources according to the second light source driving signals and the driving current for the light sources to have overlapping light-emitting timings.

Projection apparatus, illumination apparatus thereof, and light source driving method thereof

A projection device, a light source system and a projection method thereof are provided. A portion of the light-emitting units are controlled to provide a light beam as the first light beam. It is detected whether characteristic parameters of the light-emitting units providing the light beam reach a preset value. When the preset value is not reached, the light-emitting units providing the light beam are disabled, and the remaining light-emitting units are controlled to provide the back-up light beam as the first light beam. A portion of the first light beam is converted into a second light beam. The first light beam of which the wavelength is not converted and the second light beam are combined to generate an illumination beam. The illumination beam is converted into an image beam. The image beam is converted into a projection beam.

Projection device and light source system and projection method thereof

A display panel has a portion of a color filter or patterned color layer with a thickness of at least half of the cell gap of the display panel, wherein the repair method includes providing a energy light beam to the portion of the color filter or the patterned color layer in the sub-pixel region with a bright point defect to make the portion of the color filter or patterned color layer have porous structure so that bright point is repaired to become a grey point or a dark point.
