Abstract
Liquid Crystal Display (LCD), 3D imaging apparatus and operating methods thereof are disclosed. The operating method for the disclosed LCD includes the steps of: driving a pixel array of the LCD to display a frame of data by a first frame scan and a second frame scan; and, controlling a backlight module of the LCD in accordance with the first frame scan and the second frame scan. In the first frame scan, the scan lines of pixel array are driven in groups, wherein, in each group, all rows corresponding thereto are driven by identical data. The rows which have not been driven by correct data in the first frame scan are driven again and corrected in the second frame scan.
Claims13
A liquid crystal display, comprising:
- a pixel array including a plurality of pixels, the pixels arranged at intersections of a plurality of scan lines and a plurality of data lines;
- a backlight module;
- and
- a driver module, driving the pixel array to display a frame of data by a first frame scan and a second frame scan, and controlling the backlight module in accordance with the first frame scan and the second frame scan,
- wherein:
- the driver module performs the first frame scan to drive the scan lines of the pixel array group by group wherein, in each group, rows of the pixels are written identical row data by the first frame scan;
- the driver module performs the second frame scan after the first frame scan, to correct the data of the pixels in the second frame scan;
- the backlight module illuminates the pixel array and illumination on different areas of the pixel array are controlled separately, wherein the rows of the pixels which have been scanned in the second frame scan are qualified to be illuminated by the backlight module;
- and
- the driver module performs a first blank scan after the first frame scan and prior to the second frame scan, and performs a second blank scan consecutively after the second frame scan.
A liquid crystal display, comprising:
- a pixel array including a plurality of pixels, the pixels arranged at intersections of a plurality of scan lines and a plurality of data lines;
- a backlight module;
- and
- a driver module, driving the pixel array to display a frame of data by a first frame scan and a second frame scan, and controlling the backlight module in accordance with the first frame scan and the second frame scan,
- wherein the driver module performs the first frame scan to drive the scan lines of the pixel array group by group wherein, in each group, rows of the pixels are written identical row data by the first frame scan,
- wherein the driver module performs the second frame scan after the first frame scan, to correct the data of the pixels in the second frame scan,
- wherein each group of the scan lines includes at least three scan lines, and
- wherein the driver module performs a first blank scan after the first frame scan and prior to the second frame scan, and performs a second blank scan consecutively after the second frame scan.
An operating method for a liquid crystal display, comprising:
- performing a first frame scan and a second frame scan to drive a pixel array of the liquid crystal display to display a frame of data, the pixel array including a plurality of pixels arranged at intersections of the scan lines and the data lines;
- and
- controlling a backlight module of the liquid crystal display in accordance with the first frame scan and the second frame scan,
- wherein at least every three scan lines of the pixel array are regarded as one group, and the scan lines of the pixel array are driven in the first frame scan group by group, and, in the first frame scan, the rows scanned by the scan lines of the same group are driven by identical data,
- wherein the data of the pixels are corrected in the second frame scan, and
- wherein a first blank scan is performed after the first frame scan and prior to the second frame scan, and a second blank scan is performed consecutively after the second frame scan.
