Embodiments of a display panel, a display panel control method, and a display device are provided, and the following description will be made with reference to fig. 1 to 8.
Referring to fig. 1 to 3, a display panel 10 according to an embodiment of the present invention has a bending area WA and a non-bending area FA adjacent to the bending area WA, and the display panel 10 includes: the supporting layer 1 comprises a normal supporting part 11 positioned in the non-bending area FA and a stretchable supporting part 12 which is arranged adjacent to the normal supporting part 11 and positioned in the bending area WA; the display layer 2 is arranged on one side of the support layer 1, the display layer 2 comprises a normal display part 21 located in the non-bending area FA and a stretchable display part 22 which is arranged adjacent to the normal display part 21 and located in the bending area WA, the normal display part 21 and the normal support part 11 are correspondingly arranged, and the stretchable display part 22 and the stretchable support part 12 are correspondingly arranged.
The display panel 10 provided by the embodiment of the invention comprises a support layer 1 and a display layer 2, wherein the display layer 2 is arranged on one side of the support layer 1 so as to support and fix the display layer 2 through the support layer 1, the display panel 10 has an unfolded state and a folded state, when the unfolded state is changed into the folded state, the stretchable display part 22 of the display layer 2 and the stretchable support part 12 of the support layer 1 are stressed, bent and stretched, namely the stretchable display part 22 and the stretchable support part 12 can generate stretching deformation during bending, so that the received bending stress is slowly released, the time for generating cracks and bending marks in a bending area WA of the display panel 10 after long-term bending is delayed, the crease generated by the bending of the display panel 10 is reduced, the service life of the bending area WA is prolonged, the use stability of the bending area WA is improved, and the display effect and the user visual experience of the bending area WA are improved.
In this embodiment, the normal display portion 21 and the normal support portion 11 are disposed correspondingly, specifically, the normal display portion 21 just covers the normal support portion 11, so that neither the normal display portion 21 nor the normal support portion 11 needs to be bent or stretched, and both can be disposed correspondingly. Similarly, the stretchable display portion 22 and the stretchable support portion 12 are correspondingly disposed, the stretchable display portion 22 just covers the stretchable support portion 12, and both portions are bent and stretched together, optionally, in order to facilitate the stretchable display portion 22 and the stretchable support portion 12 to stretch, part of the film layers of the stretchable display portion 22 and the stretchable support portion 12 may be made of a material with good elasticity, such as CPI (color Polyimide), a super-elastic material, etc., so as to ensure the stretchable performance of the stretchable display portion 22 and the stretchable support portion 12.
In order to detect the stress applied to the display panel 10 when the display panel 10 is bent, and determine whether the display panel 10 is in the unfolded state or the folded state according to the stress applied to the display panel 10 when the display panel 10 is bent, in some optional embodiments, the stretchable supporting portion 12 includes a bearing portion 121 and a tension detecting portion 122 stacked along the thickness direction of the display panel 10, and the tension detecting portion 122 includes a tension testing material and a sensor for detecting the tension change applied to the tension testing material.
It should be noted that, because the stress applied to the tension test material of the tension detection portion 122 when the tension test material is bent and stretched is greater than the stress applied to the tension test material of the tension detection portion 122 when the tension test material is in a flat state, that is, when the stress applied to the tension test material is greater than or equal to a predetermined value, it can be determined that the display panel 10 is in a folded state, and when the stress applied to the tension test material is less than the predetermined value, it can be determined that the display panel 10 is in an unfolded state, because the use areas of the display panel 10 in the unfolded state and the folded state are different, that is, the areas that need to be displayed and touched are different, the display and touch areas of the display panel 10 can be correspondingly controlled according to the above stress detection result, and the use experience of the user can be ensured. The stress applied to the tensile test material can be measured indirectly by the deformation of the tensile test material, and is not particularly limited.
The tension test material can be a super-elastic material, and the super-elastic material is a material which has an elastic potential energy function, wherein the function is a scalar function of a strain tensor, and a derivative of the function corresponding to a strain component is a corresponding stress component, and the strain can be automatically recovered when the material is unloaded. Commonly used are rubber, sponge, etc. Optionally, the material of the bearing part 121 includes at least one of a superelastic material and a transparent polyimide material.
Optionally, since the sensor needs to be provided with a first signal line for signal transmission, in order to avoid damage to the first signal line when the stretchable supporting portion 12 is bent and stretched, the extending track of the first signal line is at least one of a curved line and a broken line. The first signal line is not straight, but curved, broken, and the like, for example, the wave-shaped routing is adopted, so that the first signal line has a certain stretchable space when being stretched, the first signal line is prevented from being directly straightened and damaged, and the extending track of the first signal line is set to be at least one of the curved line and the broken line, so that the routing length of the first signal line is increased, and a certain redundant length is provided for subsequent stretching.
In order to avoid a step difference between the normal display portion 21 and the stretchable display portion 22 of the display layer 2, which may cause damage to the second signal line X between the normal display portion 21 and the stretchable display portion 22, in some alternative embodiments, a side surface of the tensile force detecting portion 122 facing away from the bearing portion 121 and a side surface of the normal supporting portion 11 facing the display layer 2 are flush with each other. That is, the normal display portion 21 and the stretchable display portion 22 respectively located on the normal supporting portion 11 and the tensile force detecting portion 122 are located on the same plane, and there is no step difference between the two, so that when the display panel 10 is bent, the second signal line X between the normal display portion 21 and the stretchable display portion 22 can be prevented from being damaged due to the step generated by the step difference.
Referring to fig. 4 and 5, considering that the stretchable display portion 22 has some second signal lines X for transmitting display signals, and in order to avoid damage of the second signal lines X during the bending and stretching process, optionally, the stretchable display portion 22 includes the second signal lines X, and the extending track of the second signal lines X is at least one of a curved line and a broken line, it can be understood that, as the same as the arrangement form of the first signal lines, the extending track of the second signal lines X is made into a curved line and a broken line, for example, in the form of a wave-shaped trace, so as to increase the trace length of the second signal lines X, so that the second signal lines X have a certain stretchable space when being stretched, and provide a certain redundant length for subsequent stretching.
Alternatively, the second signal lines X may include at least one of data lines, scan lines, and voltage signal lines, that is, the second signal lines X may be signal lines for transmitting data signals, scan signals, voltage signals, and the like in the stretchable display portion 22.
In some alternative embodiments, the stretchable display portion 22 includes a plurality of light emitting cells F electrically connected to each other through the second signal line X. The specific extending track and length of the second signal line X may be selected according to the distance between two adjacent light emitting units F, and are not particularly limited.
Alternatively, the second signal line X is disposed on the array substrate of the stretchable display portion 22 and between the pixel circuit of the array substrate and the light emitting unit F.
Referring to fig. 6, in some alternative embodiments, in the thickness direction of the display panel 10, the normal display portion 21 includes a first electrode layer 4, a first light emitting material layer 5 and a second electrode layer 6 which are stacked, and the stretchable display portion 22 includes a third electrode layer 7, a second light emitting material layer 8 and a fourth electrode layer 9 which are stacked; the first electrode layer 4, the first luminescent material layer 5 and the second electrode layer 6 are arranged in a plane; and/or the third electrode layer 7, the second light emitting material layer 8 and the fourth electrode layer 9 are arranged in a curved surface.
It can be understood that, since the first electrode layer 4, the first luminescent material layer 5 and the second electrode layer 6 of the normal display portion 21 are all disposed in the non-bending region FA, no deformation such as bending, stretching, etc. occurs, and thus the first electrode layer 4, the first luminescent material layer 5 and the second electrode layer 6 can be disposed in a plane to ensure the display effect. The third electrode layer 7, the second light emitting material layer 8, and the fourth electrode layer 9 are located in the bending region WA, and when the display panel 10 is in the folded state, the third electrode layer 7, the second light emitting material layer 8, and the fourth electrode layer 9 are bent and stretched relatively, in this embodiment, by setting the third electrode layer 7, the second light emitting material layer 8, and the fourth electrode layer 9 as a curved surface, the entire area of the third electrode layer 7, the second light emitting material layer 8, and the fourth electrode layer 9 is increased, so that the third electrode layer 7, the second light emitting material layer 8, and the fourth electrode layer 9 have a certain stretchable space when being stretched, even after being stretched, the third electrode layer 7, the second light emitting material layer 8, and the fourth electrode layer 9 are not damaged due to an excessive stress, and play a role in protecting the third electrode layer 7, the second light emitting material layer 8, and the fourth electrode layer 9. Alternatively, the third electrode layer 7, the second light emitting material layer 8 and the fourth electrode layer 9 may be a wavy curved surface or a zigzag surface, and are not particularly limited.
Optionally, the display device further includes a pixel defining layer 3, wherein the pixel defining layer 3 has a pixel opening, and the pixel opening exposes at least a portion of the first electrode layer 4 and the third electrode layer 7. The pixel defining layer 3 may be made of hexamethyldisiloxane, epoxy resin or Polyimide (PI), or may be made of other silicon-based organic materials with a light transmittance of 90% or more, or other organic materials with a slightly lower light transmittance (greater than 80%) and a slightly higher bending strength, which is not limited in this embodiment.
Optionally, each pixel circuit includes a thin film transistor TFT including an active layer J, a gate electrode G, a source electrode S, and a drain electrode D, and the material of the drain electrode D, the source electrode S, and the gate electrode G may include one or a combination of molybdenum, titanium, aluminum, copper, and the like. The gate G of the thin film transistor TFT is generally used for receiving a control signal to turn the thin film transistor TFT on or off under the control of the control signal. One of the source S and the drain D of the thin film transistor TFT is connected to the light emitting unit F.
Referring to fig. 7, an embodiment of the present invention further provides a method for controlling a display panel 10, including:
s110: detecting the stress of the stretchable supporting part 12 of the display panel 10;
s120: when detecting that the stress of the stretchable supporting portion 12 is greater than or equal to a preset value, controlling the display panel 10 to output a first display picture;
s130: when detecting that the stress on the stretchable supporting portion 12 is smaller than the preset value, the display panel 10 is controlled to output a second display image.
The method for controlling the display panel 10 provided in the embodiment of the present invention may determine the state of the display panel 10 according to the stress of the stretchable supporting portion 12 of the display panel 10, and further, control the display panel 10 to output the first display picture and the second display picture in a targeted manner, specifically, when the stress of the stretchable supporting portion 12 is detected to be greater than or equal to a preset value, that is, the corresponding display panel 10 is in a folded state, at this time, only a portion of the display panel 10 located on the whole surface needs to be displayed, so that the display panel 10 needs to be controlled to output the first display picture with a smaller display area, so as to be convenient for a user to use, and when the stress of the stretchable supporting portion 12 is detected to be less than the preset value, the corresponding display panel 10 is in an unfolded state, and the display panel 10 needs to be controlled to output the second display picture with a larger display area, thereby improving the experience effect of the user.
In step S110, the tensile force detection portion 122 may specifically detect the magnitude of the applied force of the stretchable supporting portion 12, and specifically, the tensile force detection portion 122 includes a tensile force testing material and a sensor for detecting a change of the tensile force applied to the tensile force testing material, and the sensor detects the tensile deformation amount of the tensile force testing material in the flat and bent stretching states to determine the applied force, so as to determine the state of the display panel 10.
In steps S120 and S130, as shown in fig. 8, the core processor module is specifically responsible for receiving the deformation data of the tension detecting portion 122 for determining, when the amount of the tensile deformation is greater than a certain specific value X1, determining the state as the folded state, and when the amount of the tensile deformation is smaller than a certain specific value X2, determining the state as the unfolded state, and then the core processor module sends the determination result to the display picture matching module in real time, and the display picture matching module performs resolution matching in real time, and further outputs the first display picture and the second display picture.
Considering that the display panel 10 generally has a touch function, in order to match the touch with the state of the display panel 10, in some alternative embodiments, when it is detected that the force applied to the stretchable supporting portion 12 is greater than or equal to the preset value, the display panel 10 is controlled to have the touch function corresponding to the area displaying the first display screen; when it is detected that the stress of the stretchable supporting portion 12 is smaller than the preset value, the display panel 10 is controlled to have a touch function corresponding to the area displaying the second display frame.
Specifically, the display panel 10 further includes a touch matching module, and the core processor module sends the determination result to the touch matching module in real time to perform touch area matching, so that the bright screen area has a touch function, and the off screen area has no touch function, that is, when the display panel 10 is in the folded state, the area corresponding to the first display screen has a touch function. When the display panel 10 is in the unfolded state, the area corresponding to the second display frame has a touch function.
An embodiment of the present invention further provides a display device, including: a display panel 10, the display panel 10 being the display panel 10 of any of the above embodiments; and the support structure member 30 is arranged on the side, away from the display layer 2, of the support layer 1 of the display panel 10.
The supporting structure 30 is disposed on a back side of the display panel 10 for supporting and fixing the display panel 10 and driving the display panel 10 to achieve mutual conversion between a folded state and an unfolded state.
Optionally, the supporting structure 30 includes at least two supporting platforms 31 and a rotating shaft 32 connecting the two supporting platforms 31, the normal display portion 21 is disposed corresponding to the supporting platforms 31, and the stretchable display portion 22 is disposed corresponding to the rotating shaft 32.
The normal display unit 21 and the support platform 31 are closely attached to each other by means of an adhesive or the like, so as to avoid problems such as falling off. Since the stretchable display portion 22 stretches during the folding process, the stretchable display portion 22 does not need to be tightly attached to the rotation shaft 32 in order to prevent the rotation shaft 32 from affecting the stretching effect of the stretchable display portion 22.
Therefore, the display device provided in the embodiment of the present invention has the technical effects of the technical solutions of the display panel 10 in any of the above embodiments, and the structures and terms identical to or corresponding to those in the above embodiments are not repeated herein.
