Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terminology used in the embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the examples of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
As shown in fig. 1, fig. 2 and fig. 3, fig. 1 is a partially enlarged schematic view of a transparent display panel in an embodiment of the present invention, fig. 2 is a partially enlarged schematic view of another transparent display panel in an embodiment of the present invention, fig. 3 is a schematic view of a cross-sectional structure along direction AA' in fig. 1, and an embodiment of the present invention provides a transparent display panel, including: a pixel display region 1 and a light-transmitting region 2; the display film layer 3 is provided with a light-emitting device 31 in the pixel display area 1, and the light-transmitting area 2 is of a light-transmitting structure; a polarizer 4 on the light exit side of the display film layer 3 for converting the exit light of the light emitting device 31 into polarized light; a light valve film layer 5 located on a side of the polarizer 4 away from the display film layer 3, where the light valve film layer 5 is configured to convert polarized light between a polarized light a in a first direction and a polarized light b in a second direction, a solid arrow labeled a in fig. 1 is used to indicate a propagation path of the polarized light a in the first direction, and a dotted arrow labeled b is used to indicate a propagation path of the polarized light b in the second direction; the first birefringent film 61 is disposed on a side of the light valve film 5 away from the polarizer 4, and the first birefringent film 61 is configured to enable the first-direction polarized light a to exit in the pixel display area 1 and enable the second-direction polarized light b to exit in the light-transmitting area 2.
The embodiment of the present invention further provides a method for controlling a transparent display panel, which is used for the transparent display panel, and the method includes:
the light valve film layer 5 periodically converts the polarized light between a first direction polarized light a and a second direction polarized light b, each period including a first period and a second period;
in a first period, the light valve film layer 5 makes the polarized light a polarized light in a first direction;
during the second period, the light valve film layer 5 polarizes the light into the second-direction polarized light b.
Specifically, the light emitting device 31 generates light for displaying a pattern, the light is converted into linearly polarized light with a specific polarization direction at the polarizer 4, the linearly polarized light is a first direction polarized light a at the light valve layer 5 in a first period, for example, the first direction polarized light a is the same as the polarization direction of the polarizer 4, that is, in the first period, the light valve layer 5 does not change the polarization direction, when the first direction polarized light a reaches the first birefringent layer 61, the first direction polarized light a is transmitted and emitted in the first birefringent layer 61 in the original direction as ordinary light, that is, the first direction polarized light a is emitted in the pixel display area 1, at this time, the display of pixels is realized in the pixel display area 1, and the image is not displayed in the transparent area 2, but the ambient light from the back is displayed; in the second period, the linearly polarized light from the polarizer 4 is the second direction polarized light b in the light valve layer 5, for example, the polarization direction of the linearly polarized light is changed by the control of the light valve, so that the first direction polarized light a is converted into the second direction polarized light b, when the second direction polarized light b reaches the first birefringent film 61, it is refracted and emitted from the first birefringent film 61 in the light transmission area 2 as the extraordinary rays, so that, in the second period, the light of the light emitting device 31 is shifted, and the display of the pixel is realized in the light transmission area 2, for example, the broken line frame in fig. 1 and fig. 2 represents the pixel position displayed in the second period, so that, when the refresh frequency is fast, the required displayed picture can be displayed in the pixel display area 1 and the light transmission area 2 together, for example, each period is one frame, in each odd frame, pixels are displayed in the pixel display area 1, and in each even frame, pixels are displayed in the light transmission area 2, so that human eyes can feel that the pixels are arranged in the pixel display area 1 and the light transmission area 2, namely, the resolution is improved.
The transparent display panel and the control method thereof in the embodiment of the invention are provided with a pixel display area and a light transmission area, the light of a light emitting device is utilized in a time-sharing multiplexing mode, a light valve film layer is controlled to enable polarized light to be polarized light in a first direction in a first time interval, the polarized light in the first direction is emitted out from the pixel display area in a first double refraction film layer, the polarized light in the second direction is emitted from the light transmission area in a second time interval, the size of the light transmission area can be set to be larger on the basis of improving the resolution, the probability of diffraction formed by ambient light on the back of the display panel can be reduced, and therefore the ghost phenomenon caused by the diffraction can be improved.
Alternatively, in the above-described transparent display panel control method, the duration of each first period is equal to the duration of each second period, so that the display time of the pixels in the pixel display region 1 and the light transmission region 2 can be made the same to improve the display effect.
Optionally, the light valve film layer 5 is not driven in the transmissive region 2.
Specifically, the light valve film layer 5 is used for converting light from the light emitting device 31 in the pixel display area 1 between the first direction polarized light a and the second direction polarized light b, further refracting the second direction polarized light b in the first birefringent film layer 61, and emitting the light in the light transmission area 2, and for the light transmission area 2, only the ambient light on the back of the display panel needs to be directly emitted to realize transparent display, so that if the light transmission area 2 is provided with the light valve film layer 5, the light valve film layer 5 can be controlled to be not driven in the light transmission area 2.
Alternatively, as shown in fig. 4, fig. 4 is another schematic cross-sectional structure view along direction AA' in fig. 1, the light valve film layer 5 is not overlapped with the light transmitting region 2, and the light transmittance of the light transmitting region 2 can be improved by removing the light valve film layer 5 in the light transmitting region 2.
Alternatively, as shown in fig. 3 and 4, the polarizer 4 covers the transparent area 2, that is, in the transparent area 2, the ambient light at the back of the display panel is filtered to be polarized in the first direction at the polarizer 4, and in the case of removing the light valve film 5 in the transparent area 2 or making the light valve film 5 in the transparent area 2 undriven, the polarized light in the first direction in the transparent area 2 directly passes through the first birefringent film 61 as the ordinary light without the deviation of the emitting position, and although the brightness of the ambient light is lost due to the polarizer 4, the ambient light in the transparent area 2 does not generate the double image of the two beams due to the action of the light valve film 5 and the first birefringent film 61.
Alternatively, as shown in fig. 5 and 6, fig. 5 is another cross-sectional structure diagram of the direction AA 'in fig. 1, fig. 6 is another cross-sectional structure diagram of the direction AA' in fig. 1, the polarizer 4 and the light-transmitting region 2 do not overlap, that is, in the light-transmitting region 2, ambient light on the back of the display panel directly propagates to the first birefringent film layer 61, and includes light with various polarization directions, wherein the polarized light with the first direction directly passes through the first birefringent film layer 61, and the polarized light with the second direction is refracted and then emitted at other positions, compared with the structures shown in fig. 3 and 4, the ambient light is less lost, that is, the display brightness is greater, but if the polarized light with the two directions in the ambient light is emitted at positions that are farther apart, a ghost of the ambient light is easily perceived by human eyes.
Optionally, as shown in fig. 7 and fig. 8, fig. 7 is a schematic view of another cross-sectional structure along direction AA 'in fig. 1, and fig. 8 is a schematic view of another cross-sectional structure along direction AA' in fig. 1, where the transparent display panel further includes: a second birefringent film layer 62 on the side of the display film layer 3 away from the first birefringent film layer 61; in the first birefringent film layer 61, the emitting direction of the first-direction polarized light a is an optical axis symmetry direction, and the optical axis symmetry direction is perpendicular to the plane of the display film layer 3; the optical axis a2 of the second birefringent film layer 62 and the optical axis a1 of the first birefringent film layer 61 are symmetrical with respect to the optical axis.
Specifically, when the optical axis a2 of the second birefringent film layer 62 and the optical axis a1 of the first birefringent film layer 61 have the above-mentioned symmetrical optical axis relationship, when the ambient light enters from the display panel in the light-transmitting region 2, the ambient light is first decomposed into the first direction polarized light (indicated by the solid line arrow) and the second direction polarized light (indicated by the dotted line arrow), wherein the first direction polarized light is not refracted and directly exits, the second direction polarized light exits after being refracted in the second birefringent film layer 62, and then exits after being refracted symmetrically in the first birefringent film layer 61, because of the symmetrical optical axis relationship between the first birefringent film layer 61 and the second birefringent film layer 62, the ambient light entering at the same position has symmetrical transmission paths in the first birefringent film layer 61 and the second birefringent film layer 62, and finally the first direction polarized light and the second direction polarized light exit at the same position, on the one hand, the loss of brightness is reduced and on the other hand no ghosting of ambient light is caused. Note that the first birefringent film layer 61 and the second birefringent film layer 62 have equal thicknesses.
Alternatively, as shown in fig. 1 and 2, the transparent display panel includes: a plurality of pixel display regions 1 extending in the first direction h1 and arranged in the second direction h2, only two pixel display regions 1 being schematically illustrated in fig. 1; a plurality of light-transmitting regions 2 extending in the first direction h1 and arranged in the second direction h2, only one light-transmitting region 2 being illustrated in fig. 1; in the second direction h2, one light transmission region 2 is disposed between any adjacent two of the pixel display regions 1, and one pixel display region 1 is disposed between any adjacent two of the light transmission regions 2. In this way, the pixels displayed in the first period and the pixels displayed in the second period can be uniformly distributed to improve the display effect. In addition, in fig. 1, each pixel display area 1 corresponds to three columns of sub-pixels, and in fig. 2, each pixel display area 1 corresponds to one column of sub-pixels.
Alternatively, in the second direction h2, the width of any light-transmitting area 2 is greater than the width of any pixel display area 1, so that it is ensured that the pixel corresponding to the pixel display area 1 can be sufficiently shifted and displayed in the light-transmitting area 2 in the second period, and that the size of the light-transmitting area 2 is large, and diffraction of ambient light due to the small size of the light-transmitting area 2 is reduced.
Optionally, in the second direction h2, the width of any pixel display area 1 is equal, further ensuring uniform distribution of pixels to improve the display effect.
It should be noted that the specific structure of the first birefringent film layer 61 needs to be set according to actual conditions, and the principle is that in the first period, the pixels displayed by the light emitting devices 31 in the pixel display area 1 emit light directly for display, and in the second period, the pixels displayed by the light emitting devices 31 in the pixel display area 1 emit light in the adjacent light transmitting areas 2 exactly for display. As shown in fig. 9, fig. 9 is a schematic structural diagram of a first birefringent film layer according to an embodiment of the present invention, in the first birefringent film layer 61, an angle between a first-direction polarized light a and a second-direction polarized light b is a birefringent angle
Figure BDA0001927402470000083
The distance between the exit points of the first-direction polarized light a and the second-direction polarized light b is s, the thickness of the first birefringent film layer 61 is d, and the parameters in the first birefringent film layer 61 need to satisfy the following formula:
Figure BDA0001927402470000081
Figure BDA0001927402470000082
wherein θ is the optical axis angle of the first birefringent film layer 61, and noIs the refractive index of the light polarized in the first direction a, neIs the refractive index of the light polarized in the second direction b.
In addition, in the embodiment of the present invention, although the first direction polarized light and the second direction polarized light in the ambient light exit from different positions in the light-transmitting area 2, whether the light is perceived as a ghost by the human eye is also related to the distance from the human eye to the surface of the first birefringent film layer 61, for example, as shown in fig. 9, if the distance from the human eye to the surface of the first birefringent film layer 61 is short and the angle e between the two exit points on the surface of the first birefringent film layer 61 and the light of the human eye is greater than 1/60 °, the light is perceived as a ghost of the ambient light, so the structure shown in fig. 3, 4, 7 or 8 needs to be adopted; if the distance from the human eye to the surface of the first birefringent film layer 61 is relatively long, and the angle e between the two exit points on the surface of the first birefringent film layer 61 and the human eye is smaller than 1/60 °, no ghost of the ambient light is sensed, so the structure shown in fig. 5 and fig. 6 can be directly adopted.
As shown in fig. 10, fig. 10 is a schematic structural diagram of a display device according to an embodiment of the present invention, and the embodiment of the present invention further provides a display device including the transparent display panel 100.
