[0002] With the development of a full screen concept, the integrity of a screen has been paid more and more attention. Great efforts have been made to solve the problem of an incomplete screen display caused by "bang" and "widow's peak" in the related art.

The display panel comprises a display area, a first functional layer, and a second functional layer, wherein the display area is provided with pixels, said pixels comprising display elements and pixel circuits. Furthermore, the first functional layer includes pixel circuits, scanning lines and first connections, the display elements are electrically connected to the pixel circuits, and the pixel circuits are electrically connected to the scanning lines. Moreover, the second functional layer has a region that overlaps the first functional layer, the second functional layer includes drive circuits and wiring, and the drive circuits are provided so that the pixel circuits are sandwiched between the display elements and the drive circuits.

The organic light-emitting display panel includes a plurality of sub-pixel units and a plurality of pixel circuits. The sub-pixel units are defined by a bank, the plurality of sub-pixel units emits m different colors, any two adjacent sub-pixel units emit different colors, each of the plurality of sub-pixel units includes n sub-pixels emitting a same color, and each of the sub-pixels includes a first electrode, the first electrodes of any two sub-pixels are separated from each other, where m is 3 or 4, and n is an integer no less than 3. The pixel circuits are arranged in a rectangular array, the pixel circuits are in one-to-one correspondence with the sub-pixels, and each of the pixel circuits is electrically connected to the corresponding first electrode via a connecting wire.

[0005] EP0689181A1 provides a spatial light modulator array with adaptable multiplexed memory architecture. The modulator has an array of individually controllable pixels, where a predetermined number of pixels are assigned to a memory cell. The memory cell receives data from an input bus. On a signal, the memory cell transfers its data to a secondary memory, and to the activation circuitry of one of its assigned pixels. On a second signal, the pixel responds to the data on the activation circuitry. When the display time of the data is less than the load time for the memory cell, the secondary memory is set with a second signal so as to make the pixel dark and another control signal makes the pixels respond to the memory. In this way, the load time is lengthened and the data rate remains relatively low, even though the number of bits of intensity may not be the same as the number of bits of intensity used to determine the number of pixels assigned to each memory cell.

DETAILED DESCRIPTION

[0015] The present invention will be described in detail below with reference to the specific embodiments illustrated in the accompanying drawings. However, these embodiments do not limit the present invention, and changes in structure, method or function by those skilled in the related art according to these embodiments are included in the scope of the present invention.

[0016] Terms used in the present invention are only for the purpose of describing specific embodiments, and should not be construed to limit the present invention. As used in the present invention and the appended claims, "a" and "the" in a singular form intend to include a plural form, unless clearly indicated in the context otherwise. It should also be understood that, as used herein, the term "and / or" represents and contains any or all possible combinations of one or more associated listed items.

[0017] Some embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In the case of non-contradiction, the embodiments of the present invention and the features of the embodiments may be combined with each other.

[0018] A photosensitive element (including a camera, light sensing element, etc.) may be arranged under the screen to achieve a full screen effect. In this case, the light transmittance of a display area corresponding to a position of the photosensitive element may need to be considered.

[0019] In an approach, the luminous pixel density (PPI) of the display panel can be reduced, to increase a light transmissivity of a partially transparent area so as to meet the light sensing requirements under the screen. However, the transparent area also does not emit light, which leads to an increase of a proportion of the area not emitting light. Thus, the human eyes tend to identify a grid area not emitting light, which is mainly indicated as a large particle sense of pixels, a black frame between pixels and a reduction in the display effect.

[0020] As illustrated in Fig. 1, an electronic device 200 according to an embodiment of the present invention includes a device body 201, a photosensitive element 202 and a display screen 100. The photosensitive element 202 includes a camera, a light-sensing sensor, a photosensitive element, etc. The photosensitive element 202 is located in the electronic device 200 and arranged below the display screen 100. The display screen 100 is mounted to the device body 201 and combined with an optical imaging system, so as to achieve good display and imaging functions at the same time.

[0021] The electronic device 200 of the present invention may be any device with a display screen, for example, a mobile communication terminal (such as mobile phone), a PDA (personal digital assistant, handheld computer), a mobile computer, a tablet computer, a wearable device and so on.

[0022] As illustrated in Figs. 1 to 4, the display screen 100 includes a main display area 101 and a sub display area 102, and the sub display area 102 is made of a display panel 10 of the following embodiments. The main display area 101 of the present invention includes a substrate 1, a driving circuit 2, a first electrode layer 3, a light-emitting layer 4, and a second electrode layer 5 in sequence. The structure layers of the main display area 101 are basically the same with those of the sub display area 102, and the difference therebetween is that the sub display area 102 is designed with light transmittance.

[0023] The photosensitive element 202 is correspondingly arranged below the sub display area 102 of the display screen 100. The sub display area 102 may also allow the photosensitive element 202 to shoot through the sub display area 102 without affecting an image capturing effect of the photosensitive element 202, under the premise that a normal display is ensured. In this way, the photosensitive element 202 is arranged under the screen, and also a full-screen display of the electronic device 200 is achieved. The sub display area 102 may be arranged at any position of the display screen 100 according to application requirements.

[0024] In some embodiments, a size of the sub display area 102 is matched with that of the photosensitive element 202, so as to minimize the size of the sub display area 102 as much as possible, thereby reducing a size of an area of the display screen 100, which does not display, when the photosensitive element 202 is being used for image capturing, and hence improving a visual experience of a user in use of the electronic device 200.

[0025] It should be noted that, in an optional embodiment, the display screen 100 may also only be provided with a sub display area 102, which is made of a display panel 10 of the following embodiments.

[0026] As illustrated in Figs. 3 and 4, the display panel 10 according to the embodiment of the present invention includes a substrate 1 and a plurality of pixels 11 arranged on the substrate 1. The plurality of pixels 11 may be arranged on the substrate 1 in a matrix or in any shape. Each pixel 11 includes a plurality of sub pixels 111, which may also be arranged in a matrix or any shape. The light emitted by each sub pixel 111 is one of the three primary colors of red (R), green (G) and blue (B). In this way, the plurality of sub pixels 111 allow the pixel 11 to emit various colors of light through coordination of the three primary colors. The sub pixel 111 emitting RGB may be arranged in any color coordination manner, and the arrangement of RGB in the drawings is only a schematic illustration.

[0027] The sub pixel 111 includes a first electrode layer 3 on the substrate 1, a light-emitting layer 4 on the first electrode layer 3, and a second electrode layer 5 on the light-emitting layer 4. Further, the pixel 11 in the present invention also includes a driving circuit 2 arranged between the substrate 1 and the first electrode layer 3, and the driving circuit 2 is electrically coupled with the plurality of sub pixels 111. When an electric power is supplied with an appropriate voltage, the driving circuit 2 drives electric charges in the first electrode layer 3 and in the second electrode layer 5 to combine with each other in the light-emitting layer 4, such that the light-emitting layer 4 emits light.

[0028] The light-emitting layer 4 includes a plurality of light-emitting structural blocks correspondingly arranged on the first electrode layer 3. The light-emitting layer 4 may adopt an Organic Light-Emitting Diode (OLED).

[0029] In embodiments of the present invention, the substrate 1 may be a rigid substrate, for example, a transparent substrate such as a glass substrate, a quartz substrate or a plastic substrate. The substrate 1 may also be a flexible transparent substrate, such as polyimide (PI) film, so as to improve the transparency of the device.

[0030] The first electrode layer 3 is an anode layer and the second electrode layer 5 is a cathode layer. Of course, in other embodiments, the first electrode layer 3 may also be a cathode layer, and the second electrode layer 5 may be an anode layer. In an embodiment, the first electrode layer 3 is made of non-transparent materials, and the second electrode layer 5 is made of transparent materials. In another embodiment, both the first electrode layer 3 and the second electrode layer 5 are made of transparent materials. In this way, the sub display panel 10 can meet requirements of normal display and also carry out a light transmittance control according to use requirements.

[0031] In the present invention, the transparent materials may be any transparent conductive materials. In some embodiments, the transparent materials may include at least one of silver, magnesium, magnesium silver alloy, indium tin oxide, indium zinc oxide or the like, for example, indium tin oxide doped with silver or indium zinc oxide doped with silver. In some embodiments, the transparent materials for preparing the first electrode layer 3 and the second electrode layer 5 adopt the indium tin oxide doped with silver or the indium zinc oxide doped with silver, to reduce resistances of the first electrode layer 3 and the second electrode layer 5 on the basis of ensuring a high transmittance of the display panel 10.

[0032] The driving circuit 2 of the present invention includes a driving control module 21 and a drive line 22 electrically coupled with the driving control module 21. The driving control module 21 transmits a driving signal through the drive line 22. The driving control module 21 is used to driving electric charges in the first electrode layer 3 and the second electrode layer 5 to combine in the light-emitting layer 4, such that the light-emitting layer 4 emits light.

[0033] In some embodiments, the driving control module 21 includes one or more control switches, resistances, capacitances and other components. The driving control module 21 connects a plurality of control switches in series or in parallel as required. The driving circuit 2 is a 2T1C circuit, or 3T1C circuit, or 3T2C circuit, or 7T1C circuit, or 7T2C circuit or other pixel circuits.

[0034] The control switch may be a thin-film transistor (TFT), which can be an oxide thin film transistor or a low temperature polysilicon thin film transistor (LTPS TFT). In some embodiments, the thin film transistor may be an indium gallium zinc oxide thin film transistor (IGZO TFT). Alternatively, the control switch may also be a metal oxide semiconductor field effect transistor (MOSFET), or other elements with switching characteristics in the related art, such as an insulated gate bipolar transistor (IGBT). The electronic element that can realize the switch function in this embodiment and also can be integrated into the display panel 10 should be included in the protection scope of the present invention.

[0035] The driving control module 21 is arranged below a part of the sub pixels 111 electrically coupled with the driving circuit 2, and the drive line 22 is electrically coupled with the sub pixels 111 respectively to drive the sub pixels 111 to emit light. In this embodiment, since the driving control module 21 does not have light transmittance, the sub pixels 111 share one driving circuit 2, so as to reduce an area of an opaque portion in the display panel 10 as much as possible. In the present invention, one driving circuit 2 is shared by the sub pixels 111 to reduce the number of the driving circuits 2 and the area occupied thereby, thus further enhancing a light transmittance effect of the display panel 10.

[0036] Further, in order to reduce a size of the driving circuit 2, the driving control module 21 in the present invention is arranged below any one of the sub pixels 111 electrically coupled to the driving circuit 2. Further, in embodiments of the present invention, the sub pixels 111 electrically coupled with the same driving circuit 2 are sub pixels 111 having the same emission color, thus facilitating the control of the driving circuit 2 and the regulation of the display of the display panel 10.

[0037] As illustrated in Fig. 4 and Fig. 5, the driving circuit 2 includes a first driving circuit 211, a second driving circuit 212 and a third driving circuit 213. The emission colors of the sub pixels 111 connected with the first driving circuit 211, the second driving circuit 212 and the third driving circuit 213 are different from each other. For example, the sub pixels 111 connected with the first driving circuit 211 emit red (R) light, the sub pixels 111 connected with the second driving circuit 212 emit green (G) light, and the sub pixels 111 connected with the third driving circuit 213 emit blue (B) light.

[0038] In an embodiment, as illustrated in Fig. 4, the driving control modules 21 in the first driving circuit 211, the second driving circuit 212 and the third driving circuit 213 are arranged below different pixels 11 respectively, so as to weaken the opacity of the driving control module 21 in the driving circuit 2, thus improving the whole light transmittance effect of the display panel 10 and avoiding the concentration of the driving control modules 21, which otherwise leads to obvious black spots on the display panel 10.

[0039] In another embodiment, as illustrated in Fig. 5, the driving control modules 21 in the first driving circuit 211, the second driving circuit 212 and the third driving circuit 213 are arranged below the same pixel 11, in such a way that the opaque portions, i.e. the driving control modules 21 are concentratedly arranged to avoid an image capturing area of the photosensitive element, so as to enhance the light transmittance in other positions of the display panel 10 and improve the image capturing effect of the photosensitive element. As illustrated in Fig. 6, in an example, for example, in a 2*2 pixel 11, the driving control modules 21 are arranged below one of the pixels 11, and the other three pixels 11 are connected through the drive lines 22, such that one driving control module 21 controls four pixels 11, thus meeting the display effect of the display panel 10, and the other three pixels 11 have good light transmittance when not displaying, thus facilitating the image capturing of the photosensitive element.

[0040] As illustrated in Fig. 7, in this embodiment, the display panel 10 includes a plurality of pixel arrays, and pixel array is composed of pixels 11. In each pixel array, the pixels 11 provided with the driving control modules 21 are arranged adjacent to each other, such that the pixels 11 provided with the driving control modules 21 are positioned in the middle of the pixel array. In an example, as illustrated in Fig. 7, the pixel array is composed of four 2*2 pixels 11. In the 2*2 pixel 11, the driving control modules 21 are arranged below one of the pixels 11, and the other three pixels 11 are connected through the drive line 22. In this example, the pixels 11 provided with the driving control modules 21 among the four 2*2 pixels are concentrated in the middle of the pixel array, so as to avoid scattering or reflection of the whole display panel 10 due to the dispersed driving circuits 2, which otherwise causes stray light to be generated when exit light converges on an imaging surface, and thus reduces the overall imaging quality of the display panel 10.

[0041] At present, in the display panel 10, since incident light will be scattered or reflected by the driving circuit 2 or other opaque materials, the exit light deviates from a direction of the incident light, such that the stray light is generated when the exit light converges on the imaging surface, thus reducing the imaging quality of the display panel 10. In order to solve this technical problem, as illustrated in Fig. 8, the display panel 10 in the present invention also includes a light shielding layer 7 arranged between the substrate 1 and the driving circuit 2, and the light shielding layer 7 covers the pixels 11 provided with the driving control modules 21. The arrangement of the light shielding layer 7 can effectively reduce the imaging quality loss caused by scattering or reflection, and improve the resolving power of the display panel 10.

[0042] For the overall layout of the driving circuit 2 in the display panel 10, at least three embodiments are included as follows.

[0043] In an embodiment, as illustrated in Fig. 9, a plurality of driving control modules 21 are provided in the driving circuit 2, and uniformly distributed in the display panel 10, so as to weaken the opacity of the driving control modules 21 in the driving circuit 2, thus improving the whole light transmittance effect of the display panel 10 and avoiding the concentration of the plurality of driving control modules 21, which otherwise leads to obvious black spots on the display panel 10.

[0044] In an example, as illustrated in Fig. 10, a plurality of driving control modules 21 are provided in the driving circuit 2, and arranged at an edge of the display panel 10, such that the driving control modules 21 are located at a periphery of a lens in the molded component, thus facilitating improvements of the photosensitive effect of the photosensitive element.

[0045] In another example, as illustrated in Fig. 11, a plurality of driving control modules 21 are provided in the driving circuit 2, and arranged below the pixels 11 in the center of the display panel 10, such that the opaque driving control module 21 are concentratedly arranged, so as to improve the overall imaging quality of the photosensitive element.

[0046] The display panel in the present invention improves the structure of the driving circuit layer to reduce the number of opaque driving control modules in the driving circuit layer. With the sub pixels sharing one driving control module, the display effect of the display panel can be met, and also the light transmissivity of the display panel can be improved.

[0047] The above embodiments take the camera under the screen as an example for exemplary explanations. Of course, the display panel with the light transmittance effect in the present invention is not limited to being applied to the camera under the screen, but also may be applied to a light sensing element such as a light sensing sensor, a fingerprint unlocking element under the screen, etc., which are not specifically limited herein.

In some cases, the actions recited in the claims can be performed in a different order and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results. In certain implementations, multitasking or parallel processing may be utilized.

Other embodiments of the invention will be apparent to those skilled in the art in view of the specification and drawings of the present invention. That is, although specific embodiments have been described above in detail, the description is merely for purposes of illustration.
