  • Patent number: 11966107
    Abstract: An anti-peep display device includes a display module and an anti-peep module disposed on the display module. The anti-peep module includes the following features. The first light incident surface faces the display surface, the second and third light incident surfaces are located on opposite sides of the first light incident surface, the first condensing portion is disposed corresponding to the second light incident surface and the first light source, the second condensing portion is disposed corresponding to the third light incident surface and the second light source, the first and second condensing portions convert beams of the first and second light sources into anti-peep beams with a beam angle less than 10 degrees, and the optical microstructures reflect the anti-peep beams and exit the anti-peep beams from the light guide plate. The present invention also provides an anti-peep method applicable to the anti-peep display device.

  • Patent number: 11955070
    Abstract: A first driver circuit is configured to cooperate with a second driver circuit to control a display panel, wherein the first driver circuit is configured to output display data to a first area of the display panel and the second driver circuit is configured to output display data to a second area of the display panel. A method used for the first driver circuit includes outputting at least one emission control signal to control the second area of the display panel when the second driver circuit is disabled.

  • Patent number: 11940737
    Abstract: A method includes receiving a device design layout and a scribe line design layout surrounding the device design layout. The device design layout and the scribe line design layout are rotated in different directions. An optical proximity correction (OPC) process is performed on the rotated device design layout and the rotated scribe line design layout. A reticle includes the device design layout and the scribe line design layout is formed after performing the OPC process.

  • Patent number: 10992874
    Abstract: The present application related to a camera system and a camera fill light method. The camera system establishes a wireless communications connection with a fill light, captures an original image by a camera in the camera system, and then transmits a first test light signal to the fill light such that a first flash is performed by the fill light. The camera captures a first light source image during the first flash period of the fill light. A fill light controller in the camera system compares differences of the brightness or the chroma of different image information and, after determining the present location of the fill light, calculates a dislocation result of the present location of the fill light and the best placement location of the fill light. The camera system yields the dislocation result to the photographer via a notification message.

  • Publication number: 20140177198
    Abstract: A light source module includes a light guide plate, a reflective plate, and at least one light emitting component. The reflective plate is provided at one side of the light guide plate, and the light emitting component is adjacent to the light guide plate. The light guide plate has at least one surface having an array of plural transparent microstructures. Each of the transparent microstructures has at least one inclined angle on its lateral side. The inclined angles, the sides, and the arrangement density of the transparent microstructures can be the same or changed depending on the positions of the transparent microstructures. The shape of the transparent microstructure can be changed for different requirements. By changing the inclined angles, the sides, and the arrangement density of the transparent microstructures, the light brightness and the light uniformity can be enhanced, and the visual perception of light brightness can be increased.
