Embodiment Construction

[0037] The present invention is a display and its control method. The display has the function of switching between plane display and stereo display. The display includes: a display panel, an optical modulation panel, and a control unit. The pixel layer included in the display panel has multiple pixels (sub-pixels); multiple pixels of the optical modulation panel are used to control light. The control unit is electrically connected to the display panel and the optical modulation panel. The optical modulation panel is arranged between the viewer and the display panel. In order to meet the user's requirements, the present invention first senses the user's viewing position and uses it as a reference when controlling the display panel. The present invention first uses eye-tracking technology to obtain the eye position. It should be noted that the viewing position is not limited to the eyeball position. For example, the viewing position may represent the user's head position, e...

Abstract

A controlling method of a 2D / 3D switchable display device is provided. The display device includes an optical modulating panel with an optical modulating layer and a display panel with a pixel layer. Firstly, a viewing position is sensed, and a viewing distance and a viewing angle with respect to the viewing position are obtained accordingly. Then, a distance mode is judged according to the viewing distance. A current data set is further selected according to the distance mode and the viewing angle. The pixel layer displays the current data set which is partially filtered by the optical filter layer.

Description

Technical field [0001] The invention relates to a display and a control method thereof, and more particularly to a display that can be switched between a flat display mode and a stereo display mode and a control method thereof. Background technique [0002] When the user's eyes view an image with parallax, a stereoscopic image will be produced. The technology of auto-stereoscopic (3D) displays can be divided into two categories: barrier type and lens type. For the existing stereo display, the data combination of the pixel layer is adjusted according to the movement of the viewer's viewing position in the horizontal direction. Taking two pixels each containing three sub-pixels as an example, the data combination formed by these six sub-pixels can be data combination LLRRRL, data combination LRRRLL, data combination RRRLLL, data combination RRLLLR, data combination RLLLRR, or data combination LLLRRR One of the image data given to the right eye, and L is the image data given to th...
