Embodiment Construction

[0031] While the invention will be fully described with reference to the accompanying drawings, which contain preferred embodiments of the invention, it should be understood before proceeding that those skilled in the art may modify the invention described herein while still obtaining the benefits of the invention. Therefore, it should be understood that the following description is a broad disclosure for those skilled in the art, and its content is not intended to limit the present invention.

[0032] The present invention relates to a dual-view display and its signal compensating device and method. The signal compensating device compensates the image input signal acting on the sub-pixel, so as to prevent the image input signal that is continuously input from corresponding to the original input image input signal. Brightness effects or cross-talk caused by sub-pixels (Cross-Talk).

[0033] Referring to FIG. 1 , it is a system architecture diagram of a dual-view display accord...

Abstract

The invention relates to an electronic device, a double vision display as well as a signal compensation device and a method thereof. The signal compensation device is used for producing a plurality of image control signals so as to control a plurality of secondary pixels of a display correspondingly and enabling a backlight source to display a left-vision image and a right-vision image through the secondary pixels after passing through an optical grating. The signal compensation device comprises an input unit used for receiving a plurality of image input signals in sequence; a compensation unit used for compensating a received Nth image input signal to generate an Nth image control signal according to a value of a (N plus 1)th image input signal; and an output unit used for outputting the Nth image control signal to a secondary pixel corresponding to the Nth image input signal. The invention can reduce cost and time required during the process of avoiding the crosstalk phenomenon.

Description

technical field [0001] The invention relates to a compensation method and device for a display and its image control signal, in particular to a dual-vision display and a signal compensation method thereof. Background technique [0002] The existing dual view display (Dual View Display) utilizes a barrier (Barrier) to distinguish adjacent sub-pixels (Sub-Pixels) into two types of sub-pixels belonging to the left view and the right view. [0003] Referring to FIG. 4 , it is a display structure diagram of an existing dual-view display. As shown in the figure, after the light from the backlight is irradiated by the dual-view display, due to the structure of the fence, the user in the left view can only see the effects displayed by sub-pixels 2, 4, 6..., while the view in the right Users with side vision can only see the effects displayed by sub-pixels 1, 3, 5, . . . Therefore, the dual-view display with a single display plane can present different display effects from differen...
