The inventor of the present application considers that, since the light emitting region of the OLED display is transparent and the dark region is opaque, the light emitting region of the OLED display appears gray in the off-screen state, and the dark region appears black, that is, the rigid OLED cannot achieve the integral black effect in the off-screen state, which affects the aesthetic appearance of the rigid OLED display in the off-screen state.
The application provides an organic light emitting display panel and an organic light emitting display device, which aim to solve the technical problems in the prior art.
The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments.
As shown in fig. 1, 2 and 4, the organic light emitting display panel provided in this embodiment includes an organic light emitting substrate 1 and an electro-dimming structure 2, where the organic light emitting substrate 1 includes a display region 10.
The electro-luminescence structure 2 is located at one side of the light emitting surface of the organic light emitting substrate 1, and the orthographic projection on the organic light emitting substrate 1 covers the display area 10, and the electro-luminescence structure 2 includes a first electrode layer 201, a second electrode layer 203, and a luminescence layer 202 located between the first electrode layer 201 and the second electrode layer 203.
When the first electrode layer 301 and the second electrode layer 203 are in a power-on state, the material of the light modulation layer 202 is controlled to be in a first state so that the electro-luminescence modulation structure 2 is in a light-transmitting state, and when the first electrode layer 201 and the second electrode layer 203 are in a power-off state, the material of the light modulation layer 202 is controlled to be in a second state so that the electro-luminescence modulation structure 2 is in a light-shielding state.
Specifically, as shown in fig. 3, the present application provides an organic light emitting display panel in which an organic light emitting substrate 1 includes a substrate 101, and a pixel defining layer 102 and an organic light emitting layer 103 on the substrate 101, the pixel defining layer 102 is provided with a plurality of openings, and the organic light emitting layer 103 is located in the openings. In the area where the organic light emitting layer 103 is located, the light emitting area of the organic light emitting display panel in the prior art is generally gray in the off-screen state, so that the OLED display panel in the off-screen state has a poor integral black effect, which is more serious in the rigid OLED display panel.
In the organic light emitting display panel provided in the present application, the organic light emitting substrate 1 further includes a driving circuit film layer, an anode layer, a cathode layer, and other film layers for realizing the display of the organic light emitting display panel under the control of the driving signal.
The material of the light modulation layer 202 is an electrochromic material, and has light transmittance in the first state and an ink color in the second state, and for example, the material of the light modulation layer 202 may be an inorganic material such as tungsten oxide or molybdenum oxide, or an organic material such as an viologen derivative. These materials have different states under the influence of an electric field and under the influence of no electric field, and thus exhibit different colors.
The organic light emitting display panel provided by this embodiment is in an energized or de-energized state by controlling the first electrode layer 201 and the second electrode layer 203 to control whether the dimming layer 202 is in a light-transmitting state or a light-shielding state, so that the organic light emitting display panel normally displays, and the organic light emitting display panel is in an integrated black effect due to the fact that the dimming layer 202 is in the light-shielding state in the screen-off state, so that the attractiveness of the organic light emitting display panel in the screen-off state is improved.
Further, as shown in fig. 4, in the organic light emitting display panel provided in this embodiment, the organic light emitting substrate 1 further includes a non-display area 20, and since no light emitting pixel is disposed in the non-display area 20, the non-display area 20 can present black in the screen-off state, and therefore, only the electro-dimming structure 2 is disposed in the display area 10, which can ensure that the organic light emitting display panel presents a good black-in-one effect in the screen-off state.
As shown in fig. 5 to 11, the organic light emitting display panel provided in the present application further includes a carrying structure, the electroluminescent light modulating structure 2 is disposed on the carrying structure, the carrying structure is reused as the encapsulation glass 3 or the cover plate 7, and the encapsulation glass 3 is located between the organic light emitting substrate 1 and the cover plate. Since the electro-dimming structure 2 can be disposed at different positions, the dimming control circuit E for controlling whether to supply power to the electro-dimming structure 2 can be disposed at different positions in order to control the power-on and power-off states of the first electrode layer 201 and the second electrode layer 203, which will be described in detail below.
As shown in fig. 5 to 11, the organic light emitting display panel provided in the present application further includes a polarizer 4 and an optical adhesive 5, wherein the polarizer 4 is located between the sealing glass 3 and the cover plate 6, and the optical adhesive 5 is located between the polarizer 4 and the cover plate 6.
Alternatively, as shown in fig. 5, the organic light emitting display panel provided in this embodiment includes a dimming control circuit E in the organic light emitting substrate 1, and the dimming control circuit E is electrically connected to the first electrode layer 201 and the second electrode layer 202, respectively.
Specifically, the electrical connection between the dimming control circuit E and the first electrode layer 201 and the second electrode layer 202 can be achieved by bonding, conductive adhesive bonding, or the like.
Specifically, the organic light emitting substrate 1 further includes a pixel driving circuit, a gate driving circuit, an electrostatic discharge circuit, and the like, and the dimming control circuit in the present embodiment may be formed in the same process as the pixel driving circuit, the gate driving circuit, the electrostatic discharge circuit, and the like described above.
Alternatively, as shown in fig. 6, in the organic light emitting display panel provided in this embodiment, the organic light emitting substrate 1 is bound to the first flexible circuit board FPC1, and the first flexible circuit board FPC1 includes a dimming control circuit E electrically connected to the first electrode layer 201 and the second electrode layer 202, respectively.
Specifically, the electrical connection of the dimming control circuit E to the first electrode layer 201 and the second electrode layer 202 may be realized by a conductive structure provided in the organic light emitting substrate 1.
In the organic light emitting display panel shown in fig. 5 and 6, the dimming control circuit E is disposed on either the organic light emitting substrate 1 or the first flexible circuit board FPC1, and in order to facilitate electrical connection between the electro-luminescence dimming structure 2 and the dimming control circuit E, the electro-luminescence dimming structure 2 should be located at a short distance from the organic light emitting substrate 1. Therefore, the position of the electro-dimming structure 2 is selected similarly based on the position of the dimming control circuit E shown in fig. 5 and 6, and for the sake of simplicity of explanation, the position of the electro-dimming structure 2 will be explained by taking only the position of the dimming control circuit E shown in fig. 5 as an example.
In a specific embodiment, as shown in fig. 7, the carrier structure is reused as the encapsulation glass 3, and the electro-luminescence modulation structure 2 is located on one side of the encapsulation glass 3 close to the organic light emitting substrate 1.
Specifically, in this embodiment, the first electrode layer 201, the dimming layer 202, and the second electrode layer 203 may be deposited on the encapsulation glass 3, so that the electro-luminescence dimming structure 2 is formed on the encapsulation glass 3, and the electro-luminescence dimming structure 2 is located on the side of the encapsulation glass 3 close to the organic light emitting substrate 1, which can facilitate the electrical connection between the first electrode layer 201 and the second electrode layer 203 and the dimming control circuit E located on the organic light emitting substrate 1 or the dimming control circuit E located on the first flexible circuit board FPC 1.
Note that the thicknesses of the first electrode layer 201, the second electrode layer 203, and the light modulation layer 202 are much smaller than those of the package glass 3 and the cover glass, and fig. 7 to 8 and fig. 10 to 11 of the present application are only for illustrating the relative positional relationship between the film layers, and are not for limiting the thicknesses of the film layers.
In another specific embodiment, as shown in fig. 8, in the organic light emitting display panel in this embodiment, the carrier structure is reused as the encapsulation glass 3, the encapsulation glass 3 includes a first glass 301 and a second glass 302, and the electroluminescent dimming structure 2 is located between the first glass 301 and the second glass 302.
Specifically, the positional relationship among the first glass 301, the second glass 302 and the electro-dimmer structure 2 in this embodiment is a film structure of the light control glass, that is, common light control glass can be used as the encapsulation glass 3 and the electro-dimmer structure 2.
It should be noted that, when the light control glass is used as the encapsulation glass 3 and the light control structure 2, the thicknesses of the first glass 301 and the second glass 302 should be controlled to avoid the light control glass from being too thick, so that the thickness of the organic light emitting display panel is greatly increased.
Optionally, as shown in fig. 9, the organic light emitting display panel provided in this embodiment further includes a touch electrode layer 7, the touch electrode layer 7 is located on a surface of the cover plate 6 close to the organic light emitting substrate 1, the touch electrode layer 7 is electrically connected to the second flexible circuit board FPC2, the second flexible circuit board FPC2 includes a dimming control circuit E, and the dimming control circuit E is electrically connected to the first electrode layer 201 and the second electrode layer 202, respectively.

In the organic light emitting display panel shown in fig. 9, the dimming control circuit E is disposed on the second flexible circuit board FPC2, and in order to facilitate the electrical connection of the electro-luminescence dimming structure 2 and the dimming control circuit E, the electro-luminescence dimming structure 2 should be located closer to the organic light emitting substrate 1. The position of the electro-dimmer configuration 2 will be explained based on the position of the dimming control circuit E as shown in fig. 9.
In a specific embodiment, as shown in fig. 10, in the organic light emitting display panel in this embodiment, the carrying structure is reused as the sealing glass 3, and the electro-luminescence modulating structure 2 is located on one side of the sealing glass close to the cover plate 6.
Specifically, in this embodiment, the first electrode layer 201, the dimming layer 202 and the second electrode layer 203 may be deposited on the encapsulation glass 3, so as to form the electroluminescent dimming structure 2 on the encapsulation glass 3, and the electroluminescent dimming structure 2 is located on the side of the encapsulation glass 3 away from the organic light emitting substrate 1, which can facilitate the electrical connection between the first electrode layer 201 and the second electrode layer 203 and the dimming control circuit E located on the second flexible circuit board FPC 2.
