And the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.
Fig. 1 shows a display panel according to an embodiment of the present invention, which includes:
the light-emitting device comprises a first transparent substrate 10 and a second transparent substrate 20 which are oppositely arranged, and a plurality of first light-emitting units 30 and a plurality of second light-emitting units 40 which are arranged between the first transparent substrate 10 and the second transparent substrate 20, wherein a first light-emitting surface of each first light-emitting unit 30 faces the first transparent substrate 10, and a first light-emitting surface of each second light-emitting unit 40 faces the second transparent substrate 20, wherein the orthographic projection of each first light-emitting unit 30 on the first transparent substrate 10 and the orthographic projection of each second light-emitting unit 40 on the first transparent substrate 10 are not overlapped with each other;
a shielding film 50 is arranged between the first light-emitting unit 30 and the first transparent substrate 10, and the orthographic projection of the shielding film 50 on the first transparent substrate 10 and the orthographic projection of the first light-emitting unit 30 on the first transparent substrate 10 are alternately arranged in a strip shape;
a black matrix 60 is arranged between the second light emitting unit 40 and the second transparent substrate 20, and the orthographic projection of the black matrix 60 on the second transparent substrate 20 and the orthographic projection of the second light emitting unit 40 on the second transparent substrate 20 are alternately arranged in a strip shape;
when the first light-emitting unit 30 is in an on state and the second light-emitting unit 40 is in an off state, the display panel is in a three-dimensional tablet mode on one side of the first transparent substrate 10; when the first light emitting unit 30 is in the off state and the second light emitting unit 40 is in the on state, the display panel is in the naked eye three-dimensional display mode on the second transparent substrate 20 side.
In a specific implementation process, the first light emitting units 30 and the second light emitting units 40 are disposed in a staggered manner, and the light emitting directions are opposite, and the first light emitting units 30 and the second light emitting units 40 are not disposed on the same film layer. When the first light emitting unit 30 is in the on state and the second light emitting unit 40 is in the off state, the display panel is in the three-dimensional tablet mode at one side of the first transparent substrate 10 by the light adjusting effect of the shielding film 50 on the first light emitting unit 30. When the first light emitting unit 30 is in the off state and the second light emitting unit 40 is in the on state, the display panel is in the naked eye three-dimensional display mode on one side of the second transparent substrate through the adjustment effect of the black matrix 60 on the light of the second light emitting unit 40. Thereby realizing diversified design of display modes of the display panel.
In a specific implementation process, when the display panel is in the three-dimensional tablet mode on the first transparent substrate 10 side, the user uses the stylus to write words on the first transparent substrate 10 side, which is more stereoscopic than a blackboard in the two-dimensional mode, and the user experience effect is better.
In a specific implementation, the first light emitting unit 30 includes a first white organic light emitting unit, the second light emitting unit 40 includes a red organic light emitting unit, a green organic light emitting unit, and a blue organic light emitting unit, or the second light emitting unit 40 includes a second white organic light emitting unit and a color film layer disposed between the second white organic light emitting unit and the second transparent substrate 20. The second light emitting unit 40 shown in fig. 1 is embodied as one of the cases including a red organic light emitting unit, a green organic light emitting unit, and a blue organic light emitting unit. The direction of the arrow in the figure is the direction in which the light of the corresponding light emitting unit exits.
In an implementation process, to further realize diversified designs of display modes of the display panel, the shielding film 50 is specifically a stretchable film including Polydimethylsiloxane (PDMS), wherein light from the environment can transmit through the shielding film 50 in a stretched state. Specifically, when the shielding film 50 is in an unstretched state, the shielding film 50 has a small transmittance to external light. In a particular application, the skilled person can adjust the stretching degree of the masking film 50 according to the actual requirement of the light transmittance of the masking film 50.
In a specific application, a colored PDMS film can be made by mixing a rectangular transparent PDMS stack plate with a solution containing a color of tiny pigment particles. In the case of black dye, the transmittance of the PDMS film will decrease continuously as the doping concentration increases continuously. When the PDMS film is in an unstretched state, the material is in a fuzzy state, and light can hardly penetrate through the PDMS film. When the PDMS film is stressed to be stretched and deformed, the material is gradually in a transparent state, and a large amount of light penetrates through the PDMS film. That is, when the doping concentration of the PDMS film and the thickness of the PDMS film are fixed, the light transmittance of the PDMS film can be adjusted by adjusting the stretching degree of the PDMS film.
In a specific implementation process, as shown in fig. 2, which is a situation of each film layer corresponding to the first light-emitting unit 30, in order to implement a three-dimensional tablet mode of the display panel on one side of the first transparent substrate 10, the first transparent substrate 10 is divided into a first non-display area 100 and a first display area 101. Among them, the shielding film 50 is disposed in the first non-display area 100, and the black matrix 60 is disposed in the first non-display area 100 and the first display area 101.
In a specific implementation, as shown in fig. 3, one of the circuit structures of the display panel including the photosensitive switch unit 70 is shown. Wherein the light emitting diode 80 and the first light emitting unit 30 are designed to be common Ground (GND). In fig. 3, R is a resistor connected in series with the photosensitive switching unit 70, and when the photosensitive switching unit 70 is turned on, the power supply supplies power to the light emitting diode 80. Specifically, the display panel includes a photosensitive switching unit 70 electrically connected to the first light emitting unit 30, and the photosensitive switching unit 70 is disposed in the first non-display area 100 between the shielding film 50 and the black matrix 60. When the shielding film 50 is in a stretched state, the photosensitive switch unit 70 receives a light signal from the stylus pen to be turned on, the first light emitting unit 30 is in an open state, and the display panel is in a three-dimensional tablet mode.
In a specific application, since the photosensitive switching unit 70 is embodied as a photosensitive Thin Film Transistor (TFT), it is sensitive to invisible light emitted from a stylus pen. In order to prevent the influence of the external environmental light on the photo switch unit 70 when the display panel is in the three-dimensional tablet mode, thereby generating a malfunction of the display panel, the photo switch unit 70 may be disposed in the first non-display area 100 between the shielding film 50 and the black matrix 60. When the touch pen touches the screen, the PDMS film can be stretched to transmit light due to pressure. After the invisible light emitted by the stylus passes through the PDMS film, the photosensitive switch unit 70 is turned on, the light emitting diode 80 and the first light emitting unit 30 are all turned on, the light emitting diode 80 can emit the same invisible light as the stylus, the invisible light continuously irradiates on the channel of the photosensitive switch unit 70, the photosensitive switch unit 70 is still continuously turned on after the stylus leaves, and the stylus can continuously write other font parts. After the handwriting is finished, a low level is applied through a reset signal, and the current display content of the display panel is initialized so as to carry out the next round of handwriting process. The stylus may be an active capacitive stylus.
In addition, since the photosensitive switch unit 70 is disposed in the first non-display area 100 and between the shielding film 50 and the black matrix 60, when the touch pen does not contact the display panel, the PDMS film is in an unstretched state, and is opaque. When the touch pen contacts the display panel, the PDMS film is stretched under the action of external force, and then the light is transmitted. Once the PDMS film is transparent, the light signal of the touch pen can be received, so that the relevant writing display can be carried out. When the stylus is away, the PDMS film is restored to the unstretched state, and the PDMS film is in the opaque state, so that the photosensitive switch unit 70 is protected. When keeping apart external interference light source, effectively avoided writing mistake to display panel to touch, improved display panel's performance.
In a specific implementation process, as shown in fig. 4, which is a situation of each film layer corresponding to the second light emitting unit 40 in the display panel provided in the embodiment of the present invention, the second transparent substrate 20 includes a second non-display area 200 and a second display area 201, the black matrix 60 is disposed in the second non-display area 200, and the shielding film 50 is disposed in the second non-display area 200 and the second display area 201; when the shielding film 50 is in a stretched state, the first light emitting surface of the second light emitting unit 40 faces the second transparent substrate 20, and the second light emitting surface of the second light emitting unit 40 faces the first transparent substrate 10, and when the second light emitting unit 40 is in an open state, the display panel is in the two-dimensional display mode 2D on the first transparent substrate 10 side, and the display panel is in the naked-eye three-dimensional display mode 3D on the second transparent substrate 20 side. At this time, the display mode of the display panel is as shown in fig. 5. In a specific implementation process, the second light emitting unit 40 may emit light in two directions, a first light emitting surface of the second light emitting unit faces the second transparent substrate 20, and a second light emitting surface of the second light emitting unit faces the first transparent substrate 10.
In a specific implementation process, as shown in fig. 6, a schematic diagram of a film structure corresponding to a first light emitting unit in a display panel includes a reflective layer 90, in order to improve writing contrast of the display panel in a three-dimensional tablet mode when the first light emitting unit 30 is in an open state and increase user experience, the reflective layer 90 is disposed on a side of the black matrix 60 away from the second transparent substrate 20 in the first non-display area 100 and the first display area 101. The reflective layer 90 may sufficiently reflect light from the outside, thereby improving the contrast of the display panel.
In a specific implementation process, a user can control the display panel to be in different display modes according to a specific use scene. For example, in an outdoor scene, since sunlight is reflected seriously, at this time, the first light emitting unit 30 using the white organic light emitting unit has a better writing function in the three-dimensional tablet mode due to higher black-white contrast. At this time, by controlling the first light emitting unit 30 to be in the on state and the second light emitting unit 40 to be in the off state, a better three-dimensional tablet mode can be provided to the user. For another example, in an indoor scene, the first light emitting unit 30 may be controlled to be in an off state, and the second light emitting unit 40 may be controlled to be in an on state, so that a naked eye three-dimensional display mode and a two-dimensional display mode can be provided for a user, and a better display effect is achieved. Of course, in practical applications, the material characteristics and the on/off states of the first light emitting unit 30 and the second light emitting unit 40 may be set according to the actual mode requirements of the display panel, which is not limited herein.
In a specific implementation process, the first transparent substrate 10 and the second transparent substrate may be flexible substrates, and when a user stretches the display panel, the shielding film 50 is stretched, and at this time, when the first light emitting unit 30 is in a closed state and the second light emitting unit 40 is in an open state, the display panel may simultaneously have a two-dimensional display mode on one side of the first transparent substrate 10 and a naked-eye three-dimensional display mode on one side of the second transparent substrate 20, so that the usability of the display panel is improved while the diversification of the display modes of the display panel is ensured. When the user does not stretch the display panel, the shielding film 50 is not stretched and is opaque, and when the first light emitting unit 30 is in the closed state and the second light emitting unit 40 is in the open state, the display panel has a naked eye three-dimensional display mode at a side close to the second transparent substrate.
