Abstract
The invention discloses a manufacturing method of a three-dimensional display. Gamma curves of a left eye image and a right eye image are respectively arranged by angles corresponding to a left sight line and a right sight line. According to the invention, the gamma curves of the left eye image and the right eye image are respectively arranged by the angles corresponding to the left sight line and the right sight line, so that the brightness and contrast ratio of viewing three-dimensional images by observers are improved and the three-dimensional display quality is improved.
Description
Technical field
The present invention relates to the display technology field, particularly a kind of manufacturing approach of three-dimensional display.
Background technology
As everyone knows, the mankind can observe outside real world through eyes, in brain, form image, and the space length difference between two different differential seat angles that human brain can be seen according to left and right sides eyes forms so-called solid (3 dimension) image.This space length difference is called as parallax.So-called 3 d display device is exactly the visual field of simulating human eyes different angles, lets images of left and right eyes receive two 2 of inspection dimension images respectively, make human brain obtain the difference 2 dimension images that images of left and right eyes sees after, can be perceived as 3 dimension images.
In general, liquid crystal panel is the anglec of rotation through certain inner liquid crystal molecule, decides the light transmission capacity of liquid crystal panel, and the anglec of rotation of the liquid crystal molecule in the pixel is then relevant with the voltage difference between the common electrode with the pixel electrode of this pixel.Because of the voltage of common electrode is generally fixingly,, control the light transmittance of this pixel so can be applied to the gamma voltage on the pixel electrode by control.And different light transmittances is reacted on the visual experience of human eye is exactly the variation of brightness, and from secretly being divided into the different brightness GTG to bright variation, each GTG is represented different brightness this brightness.Like this, just can make the curve of different GTGs and brightness, as shown in Figure 1, be called gamma curve, generally be divided into 0～255 brightness rank, totally 256,0 GTG is for the darkest, and 255 GTGs are for the brightest.
And when setting gamma voltage, set carrying out brightness measurement and voltage perpendicular to panel, and the demonstration of this moment is 2 dimension pictures demonstrations, about the picture of two acceptance identical.As shown in Figure 2, when 255 GTGs, along normal perpendicular to panel; Brightness from left to right changes, and is commonly referred to as visual angle-brightness curve, and brightness is the highest when as can be seen from the figure vertical; Promptly 0 degree is the brightest when vertical, along with the angle number of degrees with normal become big; The brightness meeting diminishes, and this is because the difference of the phase difference of the liquid crystal under the different angles causes.
When carrying out 3 dimension pictures demonstrations, right and left eyes is accepted the right and left eyes picture respectively.As shown in Figure 3, can be according to seeing 3 dimensions during pictures, the relative position of eyes and display screen at ordinary times.When observer's eyes leave the display screen close together; The sight line of right and left eyes and can be bigger perpendicular to the angle between the normal of liquid crystal panel, in general the spacing of right and left eyes is 63mm, when eyes when the distance of display screen is 30cm; This angle is exactly about 6 degree, and left and right sides normal angle will reach 12 degree.If setting, the gamma of use this moment when 2 dimensions show show left and right sides picture; When left and right sides picture all showed 255 GTG brightness, owing to there is bigger normal angle, the actual brightness meeting that arrives right and left eyes was less than 255 GTG brightness; As shown in Figure 4; Like this just cause brightness with low, contrast descends, and can not show actual image information really.
Summary of the invention
Goal of the invention: the problem and shortage to above-mentioned existing existence the purpose of this invention is to provide a kind of manufacturing approach that improves the three-dimensional display of picture brightness and contrast.
Technical scheme: for realizing the foregoing invention purpose, the technical scheme that the present invention adopts is a kind of manufacturing approach of three-dimensional display, sets the gamma curve of left eye picture and right eye picture respectively through the angle of corresponding left eye sight line and right eye sight line.
Can be with left eye sight line and right eye sight line respectively as left eye normal and right eye normal, make the measurement of the brightness that gamma curve needs and the setting of gray scale voltage along left eye normal and right eye normal respectively.
The present invention can not only be used for LCD, also can use the display that uses gamma curve at other, like plasma display, OLED (Organic Light-Emitting Diode, Organic Light Emitting Diode) display etc.
Beneficial effect: the present invention sets the gamma curve of left eye picture and right eye picture respectively through the angle of corresponding left eye and right eye, can improve the brightness and contrast that the observer sees when viewing and admiring stereoscopic picture plane, has improved the stereo display quality.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment; Further illustrate the present invention; Should understand these embodiment only be used to the present invention is described and be not used in the restriction scope of the present invention; After having read the present invention, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the present invention.
As shown in Figure 3, can be according to seeing 3 dimensions during pictures at ordinary times, the relative position of eyes and display screen carries out the measurement of brightness and the setting of voltage in the position of right and left eyes respectively, makes the gamma curve of left eye and right eye respectively.As shown in Figure 5, with left eye sight line and right eye sight line respectively as normal, when showing the left and right sides picture of 255 GTGs; Along the right and left eyes normal, brightness from left to right changes, right and left eyes brightness-visual angle curve of making; As can be seen from the figure sight line is a right and left eyes normal 0 when spending in the left and right sides, and brightness is the highest, all is 255 GTG brightness; The brightness that right and left eyes is seen all there is not reduction, so than the method for setting gamma curve originally at vertical panel, improved the brightness that the observer sees; Also improve contrast level, improved display quality.
Claims (2)
1. the manufacturing approach of a three-dimensional display is characterized in that: the gamma curve of setting left eye picture and right eye picture through the angle of corresponding left eye sight line and right eye sight line respectively.
2. according to the manufacturing approach of the said a kind of three-dimensional display of claim 1; It is characterized in that: left eye sight line and right eye sight line respectively as left eye normal and right eye normal, are made the measurement of the brightness that gamma curve needs and the setting of gray scale voltage along left eye normal and right eye normal respectively.
