Image display device and image display method

摘要

Provided are an image display device and an image display method, which is capable of increasing charging period and reducing switching frequency of driving data while performing display device driving. The image display device comprises combined pixels of m columns and n rows, wherein each of the combined pixels comprises a first row of sub-pixels and a second row of sub-pixels beneath the first row of sub-pixels, wherein in a 2D image display mode, both the first rows of sub-pixels and the second rows of sub-pixels in the respective rows of combined pixels are driven and receive 2D display data; and in a 3D image display mode, one row of sub-pixels in the respective rows of combined pixels receives data and the other row of sub-pixels in the respective rows of combined pixels do not receive data.

主权项

1. An image display device comprising:
an image display panel for displaying a 2D image or a 3D image by using a plurality of combined pixels, wherein each of the plurality of combined pixels in the image display panel comprises a first row of sub-pixels and a second row of sub-pixels beneath the first row of sub-pixels, the first row of sub-pixels and the second row of sub-pixels form the combined pixel together, and for an individual row of combined pixels, a first gate line is connected to the first row of sub-pixels and a second gate line is connected to the second row of sub-pixels; a driving unit for driving the first rows of sub-pixels and the second rows of sub-pixels in the respective rows of combined pixels simultaneously when the image display panel is in a 2D image display mode, and for driving one row of sub-pixels in the respective rows of combined pixels and not driving the other row of sub-pixels in the respective rows of combined pixels when the image display panel is in a 3D image display mode; a transmitting unit for simultaneously transmitting display data to the first rows of sub-pixels and the second rows of sub-pixels in the respective rows of combined pixels, which are driven by the driving unit, when the image display panel is in the 2D image display mode, and for transmitting display data to one row of sub-pixels in the respective rows of combined pixels, which are driven by the driving unit, and not transmitting data to the other row of sub-pixels in the respective rows of combined pixels, which are not driven by the driving unit, when the image display panel is in the 3D image display mode, wherein when the image display panel is in the 3D image display mode, the driving unit sequentially drives the second rows of sub-pixels in the respective rows of combined pixels and does not drive the first rows of sub-pixels in the respective rows of combined pixels, and the transmitting unit sequentially transmits black picture data to the second rows of sub-pixels in the respective rows of combined pixels, which are driven by the driving unit, and does not transmit the display data to the first rows of sub-pixels in the respective rows of combined pixels, which are not driven by the driving unit, and wherein the second rows of sub-pixels and the first rows of sub-pixels are not scanned progressively in a same frame.
