Abstract

The invention relates to a eyeglass driving method which is suitable for a common 120Hz liquid crystal display to carry out 3D displaying and especially relates to a3D eyeglass driving method. left and right eyeglasses of the eyeglass are alternatively opened and closed. The method is characterized in that: each opening time is the same and each closing time is the same too; but the each opening time is 50-90% of the each closing time. The invention discloses a 3D eyeglass driving method based on the common 120Hz liquid crystal display. The driving method is obtained through adjusting an original 3D eyeglass driving time sequence. A principle is that an overlapping interval of the left and right eye signals should be decreased as much as possible. Therefore, crosstalk of the left and right eye can be mitigated at a certain degree.

Description

A kind of 3D glasses driving method

Technical field

The present invention relates to be applicable to that common 120Hz LCD carries out the glasses driving method that 3D shows, especially a kind of 3D glasses driving method.

Background technology

Compare common 2D picture, 3D is three-dimensional more true to nature, lets spectators that sensation on the spot in person is arranged.Present 3D technology can be divided into two kinds of bore hole formula and spectacles, and bore hole formula 3D technology is mainly used in industrial commercial demonstration aspect at present, and in the display device such as mobile phone; Spectacle 3D technology then is mainly used in consumer level market.Spectacle 3D technology can be divided into three kinds of aberration formula, fast gate-type and polarization types (also being look point-score, time-sharing procedure, light point-score); And bore hole formula 3D technology can be divided into lens arra, barrier fence and point to three kinds of light sources, and the principle of every kind of technology and imaging effect all have certain difference.

Summary of the invention

The purpose of this invention is to provide a kind of 3D glasses driving method, can alleviate the phenomenon that right and left eyes is crosstalked.

A kind of 3D glasses driving method; Wherein the left and right sides eyeglass of glasses replaces opening and closing, and its special feature is, wherein each time opening time is all identical; Shut-in time each time is also all identical, but the opening time is the 50-90% of shut-in time each time each time.

Wherein opening time and shut-in time sum equal 1/60 second, and the opening time equals to deduct in 1/120 second the response time of liquid crystal.

The present invention is based on a kind of 3D glasses driving method of common 120Hz LCD; This driving method drives on the timing foundation at original 3D glasses and obtains after the adjustment; Principle is exactly to reduce the interval that the right and left eyes signal overlaps as much as possible, can alleviate crosstalking of right and left eyes to a certain extent.

Description of drawings

The existing 3D glasses of Fig. 1 drive sequential chart;

Fig. 2 this patent 3D glasses drive sequential chart.

Embodiment

Fig. 1 is that general 3D glasses drive sequential chart, is not difficult to find out that from figure 3D glasses right and left eyes right and left eyes in 1/60 second time respectively opens the half the time.If the glasses of this type of drive control cooperate the liquid crystal display screen of common 120Hz very significantly right and left eyes crosstalk phenomenon can occur, therefore adopt the glasses of this type of drive control need cooperate special 3D display screen could realize 3D display effect preferably.

As shown in Figure 2, a kind of 3D glasses driving method, wherein the left and right sides eyeglass of glasses replaces opening and closing, wherein each time opening time all identical, the shut-in time each time is also all identical, but the opening time is the 50-90% of shut-in time each time each time.

The present invention proposes a kind of 3D glasses drive controlling method and can alleviate the problem that adopts common 120Hz screen 3D demonstration right and left eyes to crosstalk to a certain extent; Fig. 2 is the 3D glasses drive controlling sequential chart of this patent; From figure, can be clearly seen that right and left eyes in each time of 1/120 second glasses be not to open always, but open the specific time (less than 1/120 second).The time that left and right sides eyeglass is opened need obtain through actual calculation, for example can be divided into 1/120 second time 4 parts, and preceding 1/4 closes with the time glasses of back 1/4, and middle 1/2 time glasses are opened.The principle that this 3D glasses type of drive realizes is exactly to reduce the interval that the right and left eyes signal overlaps as much as possible, thereby alleviates the phenomenon that right and left eyes is crosstalked to a certain extent.

Claims

1. 3D glasses driving method; Wherein the left and right sides eyeglass of glasses replaces opening and closing; It is characterized in that: wherein each time opening time all identical, the shut-in time each time is also all identical, but the opening time is the 50-90% of shut-in time each time each time.

2. a kind of 3D glasses driving method as claimed in claim 1, it is characterized in that: wherein opening time and shut-in time sum equal 1/60 second, and the opening time equals to deduct in 1/120 second the response time of liquid crystal.
