The present disclosure relates to a display driving method, an apparatus and a display system.
A display has been widely used in various electronic devices such as a mobile phone, a PDA (Personal Digital Assistant), a digital camera, a computer screen or a notebook computer screen. Diversified displays gradually become one of the important characteristics of all kinds of electronic devices.
With an increasing of living standards and continuous developments of the display technology, functions of a display apparatus are more and more, and user's requirements for the display apparatus are higher and higher too. Currently, a display apparatus generally can only correspond to one user, or to multiple users watching a same video image, therefore the multiple users can only watch the same video image while using a same display apparatus, such that a requirements for watching different video images by the multiple users can not be satisfied simultaneously. For example, there is only one TV set in the family but family members want to watch their respective favorite TV programs by the TV set. However, since the TV set can display only one of the TV programs, remaining family members can not watch their favorite TV programs, which influences the user experience of the display apparatus.

Alternatively, the first image signal is the 2D image signal or the 3D image signal, and the second image signal is the 2D image signal or the 3D image signal.
Alternatively, when the first image signal is the 3D image signal, the first processing unit 402 is further operable to extract the first left-eye view signal and the first right-eye view signal from the first image signal, and the first driving unit 404 is further operable to drive the pixels of odd-numbered columns in the pixel array to display the first left-eye view signal and the first right-eye view signal alternately.

A further embodiment of the present disclosure provides a display system including a display device and glasses.
The display device includes the display driving apparatus provided by any one of the above embodiments. In addition, the display device may be any product or means having a function of displaying, such as electronic paper, a mobile phone, a tablet computer, a TV set, a display, a notebook computer, a digital photo frame, a navigator, etc. The display device is not limited thereto, as long as it includes the display driving apparatus of the above embodiments.
The glasses include odd-type glasses, even-type glasses, 3D odd-type glasses and 3D even-type glasses. The odd-type glasses may transmit the first polarized light; the even-type glasses may transmit the second polarized light; the 3D odd-type glasses includes a first left-eye lens and a first right-eye lens, the first left-eye lens and the first right-eye lens are both able to transmit the first polarized light, the first left-eye lens is in a transmission state when the pixels of odd-numbered columns of the display device display the first left-eye view signal, and the first right-eye lens is in the transmission state when the pixels of odd-numbered columns of the display device display the first right-eye view signal; and the 3D even-type glasses includes a second left-eye lens and a second right-eye lens, the second left-eye lens and the second right-eye lens are both able to transmit the second polarized light, the second left-eye lens is in the transmission state when the pixels of even-numbered columns of the display device display the second left-eye view signal, and the second right-eye lens is in the transmission state when the pixels of even-numbered columns of the display device display the second right-eye view signal.

Both left lens and right lens of the shutter-type 3D glasses contain one liquid crystal layer, which can change into a non-projective state in a case of being applied to a certain voltage, and be similar with ordinary lenses in the absence of additional voltage. Since the display device displays the left-eye image signal and the right-eye image signal of the 3D image signal alternately and the alternating frequency of the display device is synchronized with that of the shutter-type 3D glasses, a left-eye view is correspondingly transmitted through the left lens when the display device displays the left-eye view, and a right-eye view is correspondingly transmitted through the right lens when the display device displays the right-eye view. Thereby, a viewer sees different picture switched at a high speed, in his/her two eyes, which would create an illusion in his/her brain, and thus may see a stereo image. A separation of the fist image signal, the second image signal and image signals received by the left and right eyes can be realized by matching the polarizing plates with the shutter-type 3D glasses.
The described above are only specific embodiments of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any change or substitution which may be easily thought of by those skilled in the art within the technical scope disclosed by the present disclosure should all be contained in the protection scope of the present disclosure. Thus, the protection scope of the present disclosure should be subject to the protection scope of claims.
