  • Publication number: 20180109989
    Abstract: A voltage compensation circuit in a wireless communication device that performs wireless communication under a time division duplex (TDD) scheme includes a first path on which a diode is placed, a second path on which another diode is placed, and a timing controller. The first path is a path that supplies, to a transmitter-receiver, power output from a power supply and having a first voltage. The second path is a path that supplies power having a second voltage obtained by boosting the first voltage of the power output from the power supply. The timing controller switches between the first path and the second path based on information on timing of switch from signal reception to signal transmission.

    Abstract: A method produces a liquid crystal display. The display includes a plurality of pixels having sub-pixels that include one opening and one color layer. Some of the sub-pixels having the same color are continuously spaced in one direction. In the method, overlapping photolithographic patterns produce mask openings in which a color layer in two spaced adjacent sub-pixels is to be formed. The mask openings each have a size corresponding to two or more adjacent sub-pixels; and the number of sub-pixels of the same color that are continuously arranged in the one direction is at least twice the total number of sub-pixels of the same color included in each of the pixels.

  • Publication number: 20170308991
    Abstract: A semiconductor device 1 includes an image input unit 11 and an image output unit 12. The image input unit 11 receives first image data from a camera 91 and outputs second image data to a memory unit 93 through a shared bus 130. The image output unit 12 receives the second image data stored in the memory unit 93 through the shared bus 130 and outputs third image data to a monitor 92. The third image data is generated by performing an affine-conversion on the first image data. Magnification processing in the affine-conversion is not performed in the image input unit 11. In this way, it is possible to provide an excellent semiconductor device suitable for image processing or the like.
