  • Publication number: 20120229443
    Abstract: An electronic apparatus system is provided. The electronic apparatus system includes a register, a display mode computation unit, a display device and a control circuit. The register stores image information having a data input refresh frequency. The display mode computation unit generates a display mode control signal by computation based on an image characteristic categorization of the image information. The display device includes a display panel having a plurality of pixel units. The control circuit controls a display mode and a drive mode of the display panel according to the display mode control to signal to further adjust a display refresh frequency of the display panel.

  • Publication number: 20120182332
    Abstract: The invention discloses a liquid crystal display (LCD) apparatus and a brightness/luminance holding ratio compensation method. A backlight module of the LCD apparatus may form a plurality of backlight shield-blocking periods in a display frame cycle or adjust output brightness gradually, for compensating a brightness/luminance bias caused by a transmittance variance of liquid crystal cell in the low refresh rate driving LCD apparatus, so as to avoid some abnormal display effects, such as screen flicker. Besides, the LCD apparatus has better energy efficiency by utilizing a low-voltage gray level driving method or saving the power consumption of the backlight module.

  • Publication number: 20120169954
    Abstract: The invention discloses a liquid crystal display apparatus and a pixel element design thereof. The liquid crystal display apparatus includes a register, a liquid crystal display panel, a driving circuit, a dynamic frequency adjustment unit and a control circuit. The liquid crystal display panel includes a plurality of liquid crystal capacitors and a plurality of pixel units. The driving circuit includes a plurality of storage capacitors corresponding to the liquid crystal capacitors. A capacitance of the storage capacitors far exceeds a capacitance of the liquid crystal capacitors. The driving circuit casts the image information on the liquid crystal display panel. The dynamic frequency adjustment unit computes and judges based on an image characteristic classification of the image information, so as to generate a display mode control signal dynamically.
