  • Publication number: 20240111127
    Abstract: A system and a method of changeable lens self-adaptive control and compensation are provided. The system includes a lens holder, an actuator, and a controller. The lens holder carries a plurality of types of lenses. The actuator is connected to the lens holder, and drives the lens holder to move. The controller is electrically connected to the actuator, and is configured to determine whether maximum predetermined output torsion of the actuator is incapable of driving the lens holder when the lens holder is at each of positions when controlling the actuator to drive the lens holder, and to build a lookup table corresponding to each of the positions. The controller is configured to record a position to be a broken point in the lookup table in response to the maximum predetermined output torsion being incapable of drive the lens holder when the lens holder is at the position.

  • Patent number: 11221549
    Abstract: A projector includes a lens, a displacement adjusting unit, an imaging unit, a temperature sensing unit, a storage unit and a processing unit. The displacement adjusting unit is connected to the lens. The temperature sensing unit senses a current temperature. The storage unit stores a plurality of temperature ranges and a plurality of displacement variations corresponding to the temperature ranges. The processing unit receives a current image. The processing unit compares the current temperature with the temperature ranges to determine a current displacement variation corresponding to the current temperature from the displacement variations. The processing unit performs at least one of following steps according to the current displacement variation: controlling the displacement adjusting unit to adjust a displacement of the lens; adjusting a displacement of the current image on the imaging unit; and performing an image adjusting process for the current image.

  • Patent number: 10642113
    Abstract: A display device which is immune to a build-up of static electricity includes a display module and an anti-static layer. The anti-static layer is formed on a side surface of the display module. The anti-static layer includes an insulating layer on the side surface and a conductive layer stacked on the insulating layer. The conductive layer is electrically coupled to a conductive component of the display device.

  • Publication number: 20160349431
    Abstract: A backlight module comprises a light guide plate, at least one light source configured to emit a mixed light of a first primary color and a second primary color, a phosphor film capable of generating light having a third primary color, and a reflector. The light guide plate guides the mixed light to the phosphor film. A part of the mixed light excites the phosphor film to generate light having the third primary color. The light having the third primary color mixes with other parts of the mixed light to create white light. The reflector reflects light leaking from the light guide plate back to the light guide plate. A display device using the backlight module is also provided.

  • Publication number: 20160349432
    Abstract: A backlight module includes a light guide plate, a light source, and a phosphor film. The light source is secured to the light guide and includes an emitting element and a phosphor element covering the emitting element. The phosphor film includes a plurality of colored phosphor particles. The emitting element emits light with a first primary color. A lighting path is defined by the phosphor element, the light guide plate, and the colored phosphor particles, and the resulting mixed-color light is converted to a white light to illuminate a display panel. A display device with the backlight module is also provided.
