Three-dimensional display device and display control method thereof

Abstract

The invention provides a three-dimensional display device and a display control method thereof. A plurality of back light units are controlled to be simultaneously opened when the back light units receive a drive signal of a frame in a display area which is on the lowest side and a liquid crystal in the display area on the lowest side completely reacts, and each of the back light units is closed when each of the back light units starts to receive a drive signal of another frame in a corresponding display area. The brightness of each display area is controlled through a drive current of each of the back light units which the display areas correspond to. By means of the three-dimensional display device and the display control method thereof, picturecrosstalk generated by the three-dimensional display device can be reduced, ghost shadows are reduced, the three-dimensional display effect is improved, and the experiencing effect of a user is promoted.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a stereoscopic display device and a display control method thereof. Background technique [0002] In recent years, stereoscopic display technology has developed rapidly and has become a research hotspot in the industry. Stereoscopic display technology has important applications in medical, advertising, military, exhibition, games and other fields. see figure 1 , figure 1 is a schematic diagram of a stereoscopic display device in the prior art. Such as figure 1 As shown, the stereoscopic display device mainly includes a liquid crystal display 10 and shutter glasses 13 . The liquid crystal display 10 mainly includes a liquid crystal display panel 11 and a backlight module 12 . The liquid crystal display panel 11 can alternately display left-eye images and right-eye images under the condition that the backlight module 12 provides illumination. [0003] The shutter glasses 13...

AI Technical Summary

Problems solved by technology

Cooperate with the signal drive of the whole area S1, S2, S3, S4 and S5, because the left eye glass 131 closes late, the driving signal of the area S1 has been changed from the left eye frame to the next signal right eye frame, due to the presence of liquid crystal pixels Reaction time L0, resulting in both left-eye frame and right-eye frame in area S1, and afterimages will be seen in area S1

In addition, the opening time of the left-eye glass 131 is relatively early, and at the same time it provides driving signals to regions S1, S2, S3, S4, and S5. Due to the response time L0 of the liquid crystal pixels, regions S1, S2, S3, S4, and S5 will be affected to varying degrees. Influenced by a right-eye frame, there will be afterimages

[0005] Based on the above, in the prior art stereoscopic display device, there is crosstalk between left and right eye signals, which causes afterimages and affects the stereoscopic display effect.
