Embodiment 1

[0064] Embodiment 1: Frequency multiplication and time-division of 3D image signals to control LED backlight

[0065] The method for displaying a 3D image provided in Embodiment 1 includes: receiving a 3D image signal, the 3D image signal including a continuous frame of left-eye signal and a frame of right-eye signal; performing frequency multiplication processing on the 3D image signal, Obtaining n consecutive frames of left-eye signals and n consecutive frames of right-eye signals, where n is a multiple of frequency multiplication and greater than or equal to 2; the LED driving signal is driven to display the consecutive n frames of left-eye signals and consecutive n frames right eye signal;

[0066] The LED driving signal corresponding to the left eye signal in the first frame of the continuous n frames of left eye signals is off, the LED driving signal corresponding to the left eye signal in the nth frame is on, and the LED driving signal corresponding to the left eye sign...

Embodiment 2

[0091] Embodiment 2: frequency multiplication time division 3D image signal, insert black field

[0092] The method for displaying a 3D image provided by Embodiment 2 includes: receiving a 3D image signal, the 3D image signal including a continuous frame of left-eye signal and a frame of right-eye signal; inserting a black field into the 3D image signal signal, and perform frequency multiplication processing on the 3D image signal to generate continuous n frames of left-eye signals and continuous n frames of right-eye signals containing black field signals, where n is a multiple of frequency multiplication and is greater than or equal to 2; wherein , the first frame in the continuous n frames of left-eye signals is a black field signal, the nth frame is a non-black field signal, the first frame in the continuous n frames of right-eye signals is a black field signal, and the nth frame is a black field signal The frame is a non-black field signal; the LED drive signal drives and...

Embodiment 3

[0113] Embodiment 3: Control LED backlight signal on the basis of Embodiment 2

[0114] This embodiment is a further control based on the second embodiment, specifically, in Image 6 The shown method further includes: the motherboard in the TV sends the extracted synchronous control signal to the LED backlight drive control module; the LED backlight drive control module controls the frame corresponding to the black field signal according to the synchronous control signal The LED drive signal is off. In this way, there is both black field and LED backlight control.

[0115] see Figure 8 , which is a timing diagram of time-division 3D image signals, LED drive signals, and left and right eye images according to Embodiment 3 of the present invention. its with Figure 7 The difference is: for the LED drive signal, it is turned on at the frame of Rn", Ln", Rn+1", Ln+1", and it is turned off at the frame of Rn', Ln', Rn+1', Ln+1' . Among the signals received by the left eye, t...

Abstract

The invention discloses a method for displaying a 3D image, a television and glasses. The method comprises: receiving a 3D image signal which comprises a frame of left eye signal and a frame of right eye signal that are continuous; multiplying the frequency of the 3D image signal to obtain n continuous frames of left eye signals and n continuous right eye signals, wherein n is the number by which the frequency is multiplied and is more than or equal to 2; and displaying the n continuous frames of left eye signals and the n continuous right eye signals by using an LED driving signals for drive, wherein the LED driving signal corresponding to the first frame of left eye signal in the n continuous frames of left eye signals is closed, the LED driving signal corresponding to the nth frame of left eye signal is open, the LED driving signal corresponding to the first frame of right eye signal in the continuous n frames of right eye signals is closed and the LED driving signal corresponding to the nth frame of right eye signal is open. In the invention, mutual interference of left and right frames is avoided, the energy consumption of a backlight source is reduced and the cost of the whole machine is reduced.

Description

technical field [0001] The invention relates to the field of 3D technology, in particular to a method for displaying 3D images, a television set and glasses. Background technique [0002] The basic principle of realizing 3D display is to transmit two pictures with slight parallax to the left eye and right eye respectively through optical or circuit processing, without interfering with each other, and form a three-dimensional effect in the synthesis of the cerebral cortex. There are many ways to realize 3D display on LCD TV, which can be divided into glasses type and naked eye type. [0003] The naked-eye type is to attach a layer of three-dimensional grating on the surface of the liquid crystal screen, and the grating realizes the separation of the left and right eye images through optical refraction or blocking effect. As described in the patent CN 101013201A, the disadvantage of this method is that the image resolution is low and the cost of the grating is high. . [000...
