Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, of the embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Example one
The embodiment of the utility model provides bore hole 3D display panel, as shown in FIG. 1, this bore hole 3D display panel includes:
3D grating module 1, 3D grating module 1's upper substrate 11 is close to the one side of liquid crystal layer 13 is provided with driving electrode layer 12, be provided with the driving electrode on the driving electrode layer 12.
Further, as shown in fig. 1, an induction electrode layer 2 for inducing a touch signal of a user is disposed on a surface of the upper substrate 11 of the 3D grating module 1 away from the liquid crystal layer 13, and an induction electrode 21 is disposed on the induction electrode layer 2;
wherein,
when the naked eye 3D display panel displays a picture, the driving electrode layer 12 and the bottom electrode layer 14 of the 3D grating module 1 jointly control the deflection of liquid crystal molecules in the liquid crystal layer 13;
when the naked eye 3D display panel does not display a picture, the driving electrode layer 12 supplies power to the induction electrode layer 2.
Specifically, when the naked eye 3D display panel displays a picture, that is, when the naked eye 3D display panel is in a display state of a frame of picture, each driving electrode of the driving electrode layer 12 and the bottom electrode layer 14 of the 3D grating module 1 control a part of liquid crystal molecules to deflect together, so that some parts of the liquid crystal layer 13 of the 3D grating module 1 become transparent, and other parts are opaque, and the transparent areas and the opaque areas are alternately arranged to form the 3D grating.
Due to the effect of the 3D grating module 1, the images seen by the left eye and the right eye of the user have slight deviation, which are the image corresponding to the left eye and the image corresponding to the right eye, respectively, so that the user can feel the 3D image effect.
When the naked eye 3D display panel does not display a picture, that is, when the naked eye 3D display panel is in a black frame picture inserted between two frames of pictures at the time, since the 3D grating module 1 is not needed at this time, the driving electrode of the driving electrode layer 12 originally used for controlling the liquid crystal molecule deflection of the 3D grating module 1 can be switched to supply power to the sensing electrode layer 2, and at this time, the naked eye 3D display panel can sense whether a user touches the naked eye 3D display panel. When a user touches the surface of the naked eye 3D display panel with a finger, a coupling capacitor is formed between the human finger and the surface of the naked eye 3D display panel, and a part of charges of the induction electrode layer 2 are transferred to a human body from the surface of the naked eye 3D display panel and the finger, so that the electric field intensity detected by the induction electrode layer 2 is weakened, the naked eye 3D display panel can sense the position touched by the user, and further the corresponding reaction is made on the touch operation of the user.
Generally, the bottom electrode 14 is disposed on a lower substrate 15 of the 3D grating module.
It should be noted that although the touch function of the naked-eye 3D display panel is driven only when a black frame picture is inserted between two frames, the total of the display time of one frame picture and the time of the inserted black frame picture is about 16.7 microseconds. If the display time of one frame is 12 microseconds, the duration of the black frame is 4.7 microseconds, i.e. the duration of each touch operation available to the user is 4.7 microseconds. However, since the time for the user to perform one touch operation with the finger is much longer than 4.7 microseconds, even much longer than 16.7 microseconds, driving the touch function only when inserting the black frame picture does not affect the actual operation experience of the user, and since the human eyes cannot sense the pause of the picture in such a short time, the naked eye 3D display panel appears to the user that the naked eye 3D display panel is always displaying the picture, and meanwhile, the naked eye 3D display panel also supports the touch operation at all times.
In the technical scheme of this embodiment, a naked eye 3D display panel is provided, which includes a 3D grating module, wherein a driving electrode layer is disposed on one surface of an upper substrate of the 3D grating module, which is close to a liquid crystal layer, a driving electrode is disposed on the driving electrode layer, an induction electrode layer for inducing a touch signal of a user is disposed on one surface of the upper substrate of the 3D grating module, which is far away from the liquid crystal layer, and an induction electrode is disposed on the induction electrode layer; when the naked eye 3D display panel displays a picture, the driving electrode layer and the bottom electrode layer of the 3D grating module jointly control the deflection of liquid crystal molecules in the liquid crystal layer; when the naked eye 3D display panel does not display a picture, the driving electrode layer supplies power to the induction electrode layer. This bore hole 3D display panel has touch-control function and bore hole 3D display function, and, different with the simple stack of prior art, this bore hole 3D display panel will be used for supporting touch-control function's response electrode layer setting on the upper substrate of 3D grating module, and when this bore hole 3D display panel does not show the picture (plug in black picture frame), come to this response electrode layer power supply by 3D grating module 1's drive electrode, the number of piles of parts in the bore hole 3D display panel has been reduced, make this bore hole 3D display panel have high integrated nature, can simplify processing technology, and guarantee the quality easily. In addition, the number of layers of the components is reduced, so that the loss of display light can be reduced, the picture quality and the picture are improved, and the cost is lower.

In addition, since the width of the driving electrode is small and the resistance is large, when the driving electrode 121 supplies power to the sensing electrode 21, the driving electrode can be generally equally divided into a plurality of groups, each driving electrode group includes a plurality of or even more driving electrodes, and each driving electrode group supplies power to the sensing electrode 21 of the sensing electrode layer 2 once, so as to reduce the resistance when the driving electrode 121 supplies power, reduce the delay time of an electric signal, and ensure that a sufficient amount of power is supplied to the sensing electrode 21, and at the same time, a place touched by a user on the naked-eye 3D display panel can be accurately detected.
Generally, the sensing electrode 21 and the driving electrode 121 are made of Indium Tin Oxide (ITO), and are produced by a vacuum magnetron sputtering coating process, and are characterized by having suitable shielding effectiveness and light transmission in the range of 150KHz to 1GHzThe performance is much better than that of shielding glass made of common mesh material, and the resistivity is between 10-3～10-4The light transmittance can reach more than 85 percent between omega and cm.
Further, as shown in fig. 2, the sensing electrode 21 and the driving electrode 121 are respectively disposed on two sides of the upper substrate 11, and the sensing electrode 21 and the driving electrode 121 are perpendicular to each other, which is a DITO structure commonly used in the field of touch screens, and the structure can better shield interference of other electrical signals in the naked-eye 3D display panel to the sensing electrode 21, so as to improve the touch precision of the touch screen.
As shown in fig. 3, in the DITO structure, the sensing electrode layer 2 disposed on a surface of the upper substrate 11 of the 3D grating module 1 away from the liquid crystal layer 13 is attached to the protection cover 4 of the naked-eye 3D display panel through an optical adhesive 3 layer.
In general, the upper substrate 11 and the shield 4 may be made of a transparent material such as glass, plastic, or quartz.
The liquid crystal molecules in the liquid crystal layer 13 are generally arranged in a cholesteric phase.
