Abstract

The invention discloses a stereoscopic display device and a calibration method thereof. The stereoscopic display device comprises a motor and a display panel. The motor drives the display panel to rotate so as to achieve three-dimensional display. The calibration method comprises the following steps: acquiring a preset speed change curve of the motor and display parameters of the display panel; controlling the motor to operate according to the preset speed change curve so as to calibrate the rotation error of the motor; and driving the display panel to display according to the display parameters corresponding to the preset speed change curve. By means of the technical scheme, calibration of the rotation error of the motor is achieved, meanwhile, the quality of three-dimensional display pictures is effectively guaranteed, and the impression of a user is improved.

Description

technical field [0001] One or more embodiments of this specification relate to the technical field of stereoscopic display, and in particular, relate to a stereoscopic display device and a calibration method thereof. Background technique [0002] Stereoscopic display technology utilizes the retention effect of human vision, that is, the human eye's response to brightness changes is delayed due to brain processing, and the response lags by 50ms to 100ms. When the actual flicker exceeds this range, the human eye cannot detect it. The processing unit of the stereoscopic display device decomposes the 3D image into multiple 2D image slices, and projects them on a moving display device with a rate of at least 10 Hz, and generates stereoscopic vision by superimposing residual images. [0003] At present, motion display devices are usually driven by a servo motor, and the servo motor controls its rotation angle by controlling the length of the pulse time. Usually, the accuracy is no...
