  • Patent number: 8624939
    Abstract: A liquid crystal display (LCD) device includes a display control circuit to receive data of each frame of an external image signal and a liquid crystal panel. When the data of an n+1 frame currently received is the same as that of an n frame previously received, the display control circuit outputs first gray scale voltages corresponding to the data of the n+1 frame to drive the liquid crystal panel. When the data of the n+1 frame is different from that of the n frame, the display control circuit generates data of at least one inserted frame between the data of the n and the n+1 frames, and outputs second gray scale voltages respectively corresponding to the data of the at least one inserted frame and the n+1 frame to drive the liquid crystal panel to display first an image of the least one inserted frame and then that of the n+1 frame. An absolute value of a second gray scale voltage exceeds that of a first gray scale voltage for a same gray scale.

  • Patent number: 8576258
    Abstract: For improving the brightness decay of a display due to its aging, a non-volatile memory such as Flash can be used to store a brightness accumulation value of each point of the display, and each point can be compensated for its brightness accordingly. However, the non-volatile memory suffers from incorrect write-in data or temporary power disconnection, and thus the error will exist all the time to make the display non-even. Hence, the present invention uses a multiple data backups and CRC error detection, plus new/old data comparison to protect data the non-volatile memory from incorrect brightness compensation value so as to uniform the brightness of the display.

  • Patent number: 8564626
    Abstract: A line-sequential driving display that displays an image by exciting phosphor disposed on the rear surface of a face plate, transmitting light emitted from the excited phosphor through the face plate, and emitting the light from the front surface of the face plate. The display includes a light blocking layer disposed closer to the front surface of the face plate than the phosphor, the light blocking layer being configured to control the emission and non-emission of the light from the front surface on the basis of an electrical signal. Upon driving the line-sequential driving display, an area of the light blocking layer above a line-sequential driving selected line enters a light transmitting state and at least part of an area of the light blocking layer above a line-sequential driving unselected line enters a light blocking state.
