Detailed Description
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 only a part of the embodiments of the present invention, and not all of the embodiments. 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 invention provides a display screen 10, which can be applied to an electronic device 100 and aims to realize a double-sided display function of the electronic device 100 by using one display screen 10, so that the problem of thickness increase of the electronic device 100 caused by the double-sided display function is solved.
It is understood that the electronic device 100 may be, but is not limited to, a mobile phone, a tablet computer, a Personal Digital Assistant (PDA), an e-book reader, an MP3 (motion Picture Experts Group Audio Layer III) player, an MP4 (motion Picture Experts Group Audio Layer IV) player, a wearable device, a navigator, a handheld game console, etc.
The specific structure of the display screen 10 of the present invention will be described below:
as shown in fig. 1 and 2, in an embodiment of the display screen 10 of the present invention, the display screen 10 includes:
the display device comprises a display panel 11, wherein the display panel 11 comprises two display surfaces which are arranged in a back-to-back mode;
two cover layers 13, each cover layer 13 is arranged on one display surface, and the cover layers 13 are in a transparent state under the action of an electric field.
Specifically, the covering layer 13 is opaque in the initial state, and at this time, it can block the display screen of the display surface located behind it. The covering layer 13 is transparent under the action of the electric field, and can transmit the display picture of the display surface behind the covering layer. Thus, when both the cover layers 13 are transparent, the display screen of any one of the two display surfaces of the display panel 11 can be observed through the cover layer 13 in front of the display surface, thereby realizing the bidirectional display function of the display screen 10. When only one of the two covering layers 13 is transparent, the display screen of only one of the two display surfaces of the display panel 11 can be observed through the covering layer 13 in front of the display screen, so that the one-way display function of the display screen 10 is realized; when the states of the two covering layers 13 are switched to opposite states, that is, when one covering layer 13 is switched from the transparent state to the non-transparent state and the other covering layer 13 is switched from the non-transparent state to the transparent state, the orientation of the one-way display function of the display screen 10 can also be changed in the opposite direction.
It can be understood that whether the covering layers 13 are transparent or not can be controlled by the electric field, so that as long as the electric fields applied to the two covering layers 13 are respectively controlled, the display screen 10 can be freely switched between the two-way display mode and the one-way display mode, and the display orientation of the display screen 10 can be freely switched in the one-way display mode, so that the use requirements of users in different periods are met, and the use convenience of the display screen 10 is improved.
Therefore, the above structure makes one display screen 10 have both the bidirectional display function and the unidirectional display function, and the display orientation of the unidirectional display function can be switched to the opposite direction according to the actual requirement. At this time, if the display screen 10 is applied to the electronic device 100, the housing 30 of the electronic device 100 may be disposed around the display screen 10, that is, in the thickness direction of the electronic device 100, the thickness of the area where the display screen 10 is located is the smallest; therefore, the overlapping structure of the display screen, the shell and the display screen can be avoided, the thickness of the electronic device 100 with the display screen 10 provided by the invention can be reduced, the requirement of lightening and thinning the electronic device 100 can be met, and the convenience of use of a user can be improved. At this time, the capability of switching the display orientation of the one-way display function of the display screen 10 to the opposite direction according to actual requirements can effectively realize the double-sided display function of the electronic device 100. Namely, the problem of the thickness increase of the electronic device 100 caused by the fact that the two display screens 10 are used for realizing the double-sided display function of the electronic device 100 in the related art is effectively solved.
It should be noted that the covering layer 13 may be a transparent or non-transparent device implemented by electrically controlling, such as electrically controlled liquid crystal glass, electrochromic glass, or an optical switch device with a polarizer, and may use the polarization angle between two polarizers disposed opposite to each other to be perpendicular or parallel, so that the optical switch device transmits or non-transmits light.
Note that, the structure of the masking layer 13 is set as follows:
the cover layer 13 includes a first transparent substrate, a first transparent electrode layer, a dielectric material layer, a second transparent electrode layer, and a second transparent substrate stacked on the display surface in sequence, and the dielectric material layer is in a transparent state under the action of an electric field. By the design, the structure is stable, the function is reliable, and the operation is durable.
Specifically, the first transparent substrate may be a resin substrate (e.g., an acryl substrate, a polyethylene terephthalate substrate), a glass substrate, or the like; the second transparent substrate may also be a resin substrate (e.g., an acryl substrate, a polyethylene terephthalate substrate), a glass substrate, or the like.
The first transparent electrode layer is one of a cathode or an anode, and the second transparent electrode layer is the other of the cathode or the anode.
The cathode can adopt a single-layer thin metal layer structure or a multi-layer thin metal layer structure, and the material can be aluminum, gold, silver, platinum, chromium, magnesium, calcium, molybdenum, aluminum alloy, silver alloy, magnesium-silver alloy and the like; LiF can also be matched with Al and Ag to form a LiF/Al/Ag stack (stack) structure; Mg-Ag can also be adopted to match with ITO to form a Mg-Ag/ITO structure.
The anode can adopt an ITO single-layer thin film structure, an IZTO single-layer thin film structure, an ITO-IZTO double-layer thin film structure and the like. It should be noted that IZTO is an english abbreviation of indium tin zinc oxide, and is chemically expressed as InZnSnOx, and is formed by mixing and sintering indium oxide, zinc oxide, and tin oxide. ITO is indium tin oxide, which is an N-type oxide semiconductor.
The layer of dielectric material may be a layer of liquid crystal material, a layer of electrochromic material or a layer of electrowetting material. Wherein the layer of electrowetting material comprises a transparent electrolyte solution and a coloured liquid (e.g. an ink) that is insoluble in the electrolyte solution; when no electric field is applied, the colored liquid is spread flat to block the light from penetrating; when an electric field is applied, the colored liquid contracts towards two sides under the action of the electric field, so that the light path can pass through. It should be noted that, the selection of the dielectric material layer not only can effectively realize the light transmission function of the cover layer 13 under the action of the electric field, but also has simple and stable control and higher reliability.
It should be further noted that the structure of the display panel 11 may be as follows:
the display panel 11 includes a third transparent substrate, a transparent anode layer, an organic light emitting material layer, a transparent cathode layer and a fourth transparent substrate, the transparent anode layer is stacked on the organic light emitting material layer, the transparent cathode layer is stacked on the fourth transparent substrate, the third transparent substrate faces away from the transparent anode layer, the surface of the third transparent substrate forms one display surface, and the fourth transparent substrate faces away from the transparent cathode layer, the surface of the fourth transparent substrate forms another display surface.
That is, the display panel 11 at this time is a transparent organic light emitting diode display panel, that is, a transparent OLED display panel.
It can be understood that, by such a structural arrangement, not only the dual display surface structure of the display panel 11 can be effectively realized, but also the intermediate structure is effectively protected by the substrates on both sides, and the structure is more stable and reliable, so that the service lives of the display panel 11 and the display screen 10 can be effectively prolonged. And, carry out the AR through display screen 10 at this moment and experience, this display screen 10 can open "two-way demonstration" mode, and two cover layers 13 all are the transparent state in the display screen 10 promptly, like this, only need show virtual scene can, need not show the reality scene, see through display screen 10 user can directly see the reality scene, no visual deviation to make the user obtain better AR and experience.
Specifically, the third transparent substrate may be a resin substrate (e.g., an acryl substrate, a polyethylene terephthalate substrate), a glass substrate, or the like; the fourth transparent substrate may also employ a resin substrate (e.g., an acryl substrate, a polyethylene terephthalate substrate), a glass substrate, or the like.
The transparent cathode layer can adopt a single-layer thin metal layer structure or a multi-layer thin metal layer structure, and the material can be aluminum, gold, silver, platinum, chromium, magnesium, calcium, molybdenum, aluminum alloy, silver alloy, magnesium-silver alloy and the like; LiF can also be matched with Al and Ag to form a LiF/Al/Ag stack (stack) structure; Mg-Ag can also be adopted to match with ITO to form a Mg-Ag/ITO structure.
The transparent anode layer can adopt an ITO single-layer thin film structure, an IZTO single-layer thin film structure, an ITO-IZTO double-layer thin film structure and the like. It should be noted that IZTO is an english abbreviation of indium tin zinc oxide, and is chemically expressed as InZnSnOx, and is formed by mixing and sintering indium oxide, zinc oxide, and tin oxide. ITO is indium tin oxide, which is an N-type oxide semiconductor.
The organic light emitting material layer may have a single layer structure, i.e., an emission layer (EML); the structure can also be a double-layer structure, namely a Hole Transport Layer (HTL) or an Electron Transport Layer (ETL) is added on two sides of the luminescent layer (EML) to form an HTL-EML structure or an EML-ETL structure; the structure of the HTL-EML-ETL can also be a three-layer structure, namely, a Hole Transport Layer (HTL) and an Electron Transport Layer (ETL) are respectively added on two sides of the luminescent layer (EML) to form the structure of the HTL-EML-ETL; or other reasonable and effective structure.
As shown in fig. 2 and fig. 4, in order to control the display screen 10 of the present invention, the display screen 10 of the present invention may further be configured as follows:
the display screen 10 further includes a first touch panel 15, and the first touch panel 15 is disposed on a side of the cover layer 13 away from the display panel 11.
Specifically, the first touch panel 15 may be a resistive touch panel, a capacitive touch panel, an optical touch panel, a sonic touch panel, or the like.
It can be understood that, in the structure of the display screen 10 of the present invention, a touch panel is further disposed on an outer side of the covering layer 13, and a user can control the display screen 10 of the present invention through a touch operation of the touch panel, so as to effectively improve the operation convenience of the display screen 10 of the present invention. Moreover, because the touch panel is disposed outside the covering layer 13, a finger of a user can directly touch the touch panel, so that signal acquisition of the touch panel is more sensitive and accurate, and control of the display screen 10 of the invention is more sensitive and accurate.
As shown in fig. 2 and fig. 4, in order to further implement the control of the display screen 10 of the present invention, the display screen 10 of the present invention may further be configured as follows:
the display screen 10 further includes a second touch panel 17, where the second touch panel 17 is disposed on a side of the other covering layer 13 away from the display panel 11.
Specifically, the second touch panel 17 may be a resistive touch panel, a capacitive touch panel, an optical touch panel, a sonic touch panel, or the like.
It can be understood that, in the structure of the display screen 10 of the present invention, the touch panels are disposed on the outer sides of the two covering layers 13, and no matter whether the user faces the front side or the back side of the display screen 10, the display screen 10 of the present invention can be controlled by the touch operation of the corresponding touch panel, so as to further improve the operation convenience of the display screen 10 of the present invention. Moreover, because the touch panel is disposed outside the covering layer 13, a finger of a user can directly touch the touch panel, so that signal acquisition of the touch panel is more sensitive and accurate, and control of the display screen 10 of the invention is more sensitive and accurate.
As shown in fig. 1 and fig. 2, the present invention further provides an electronic device 100, where the electronic device 100 includes a housing 30 and the display screen 10 as described above, and the specific structure of the display screen 10 is described in detail in the foregoing embodiments. Since the electronic device 100 adopts all technical solutions of all the foregoing embodiments, at least all the beneficial effects brought by all the technical solutions of all the foregoing embodiments are achieved, and no further description is given here.
The housing 30 is disposed around the display screen 10. Specifically, the inner space of the housing 30 may be used for mounting components such as a motherboard, a power supply, a camera, a WIFI module, and the like; at this time, the display screen 10 may be electrically connected to the main board.
At this time, through the combination of different states (transparent or non-transparent) of the two cover layers 13 in the display screen 10 of the electronic device 100, the front display, the back display or the double-sided display of the electronic device 100 can be realized, and the three can be freely switched, so that the use requirements of users in different periods are met, and the use convenience of the electronic device 100 is improved.
Meanwhile, due to the structural arrangement, one display screen 10 has the bidirectional display function and the unidirectional display function at the same time, and the display orientation of the unidirectional display function can be switched to the opposite direction according to actual requirements. At this time, the housing 30 of the electronic device 100 is surrounded around the display screen 10, and the thickness of the area where the display screen 10 is located is the smallest in the thickness direction of the electronic device 100, so that a display screen-housing-display screen overlapping structure is avoided, the thickness of the electronic device 100 is reduced, the requirement of the electronic device 100 for being light and thin is met, and the convenience of use of a user is further improved. At this time, the capability of switching the display orientation of the one-way display function of the display screen 10 to the opposite direction according to actual requirements can effectively realize the double-sided display function of the electronic device 100. Namely, the problem of the thickness increase of the electronic device 100 caused by the fact that the two display screens 10 are used for realizing the double-sided display function of the electronic device 100 in the related art is effectively solved. In addition, the electronic device 100 has a novel appearance and a strong technological sense.
In the electronic apparatus 100, the front and back screens are mirror images in the "double-sided display" mode.

Specifically, the first frame 31 surrounds the front surface of the display screen 10, and the front surface of the display screen 10 is exposed through the middle avoiding opening of the first frame 31, so as to be observed and touched by a user. Similarly, the second face frame 33 is disposed around the reverse side of the display screen 10, and the reverse side of the display screen 10 is exposed from the middle avoiding opening of the second face frame 33 for being observed and touched by a user. The inner edge of the first frame 31 and the inner edge of the second frame 33 are spaced in the thickness direction of the electronic device 100, the inner edge of the first frame 31 is pressed against the front edge of the display screen 10, and the inner edge of the second frame 33 is pressed against the back edge of the display screen 10, so that the display screen 10 is fixed.
