Abstract

The invention is applied in the field of liquid crystal display, and provides a three-dimensional (3D) image display control method and a 3D image display control system. The method comprises the following steps of: receiving a 3D image signal from a 3D image signal source, and pre-processing the 3D image signal to obtain a first frame sequence; performing frame processing on the first frame sequence to obtain a second frame sequence consisting of a gray frame GL, a left-eye image L'', the gray frame GR and a right-eye image R'' which are continuous, wherein the frame processing comprises frequency multiplication, black frame interpolation and gray frame interpolation; and transmitting the second frame sequence to a liquid crystal screen for display, simultaneously generating a shutter glasses control signal and a backlight switching control signal according to a synchronizing signal of the second frame sequence, controlling the switching state of shutter glasses by using the shutter glasses control signal, and controlling the switching state of a backlight source of the liquid crystal display screen by using the backlight switching control signal. The embodiment of the invention fulfills the aim of definitely displaying a 3D image by performing the pre-processing and the frame processing on the 3D image.

Description

technical field

[0001] The invention belongs to the field of liquid crystal display, and in particular relates to a display control method and system for 3D images. Background technique

[0002] 3D display technology has become the mainstream of movie, computer and TV display technology. Currently, the method of realizing the shutter glasses time-sharing method is mainly to directly display 3D image signals in time-sharing. The 3D signal is composed of R frames of right-eye image signals and L frames of left-eye image signals. When the 3D signal is the R frame of the right eye image, the left eye is closed and the right eye is open, and the right eye image enters the right eye and the left eye has no image; when the 3D signal is the left eye image L frame, the left eye is open and the right eye is closed, and the left eye image enters the left eye. No image in the right eye. Although this method can display 3D images, due to visual residual effects, there will be problems ...
