The same reference numerals in the drawings denote the same or similar structures, and thus their repetitive description will be omitted. The words expressing the position and direction described in the present invention are illustrated in the accompanying drawings, but may be changed as required and still be within the scope of the present invention. The drawings of the present invention are for illustrative purposes only and do not represent true scale.
It should be noted that in the following description, specific details are set forth in order to provide a thorough understanding of the present invention. The invention can be implemented in a number of ways different from those described herein and similar generalizations can be made by those skilled in the art without departing from the spirit of the invention. Therefore, the present invention is not limited to the specific embodiments disclosed below. The description which follows is a preferred embodiment of the present application, but is made for the purpose of illustrating the general principles of the application and not for the purpose of limiting the scope of the application. The protection scope of the present application shall be subject to the definitions of the appended claims.
The following describes an organic light emitting display panel, a display device, and a display method thereof according to embodiments of the present invention with reference to the accompanying drawings. The dimensions and shapes of the various elements in the drawings are not intended to reflect the true scale of the display device and are merely intended to illustrate the invention.
As shown in fig. 1, a display device provided in an embodiment of the present invention includes: an organic light emitting display panel 100, a photosensitive element 200, and an indicator light 300; the organic light emitting display panel 100 includes a first display region 11 and a second display region 12, and the light sensing element 200 and the indicator light 300 are located at a side facing away from a light emitting surface of the first display region 11.
Wherein, the first display area 11 and the second display area 12 both include: and each pixel unit comprises a plurality of sub-pixels. For the purpose of distinguishing between the explanations, a plurality of pixel cells included in the first display region 11 are denoted as a pixel cell P11, and a plurality of pixel cells included in the second display region are denoted as a pixel cell P12; each pixel cell P11 in the first display area includes a sub-pixel designated as sub-pixel 111, and each pixel cell P12 in the second display area includes a sub-pixel designated as sub-pixel 121.
As shown in fig. 1, the occupied area of the sub-pixels 111 of the first display region 11 is smaller than the occupied area of the sub-pixels 121 of the second display region 12 in a unit area to increase the area of the light transmission region of the first display region 11.
The occupied area of the sub-pixel is defined as the unit area (1 cm)2Or 1mm2Etc.), all the sub-pixels occupy the area value of the unit area. For example, if the unit area (1 mm)2) Three sub-pixels with the same size are included, and the area of each sub-pixel is 10 μm2The occupied area of the three sub-pixels in the unit area is 30 μm2。
It can be understood that the organic light emitting display panel uses organic light emitting diode devices as light emitting sub-pixels, and the pixel units are formed by sub-pixels with different colors for displaying images. In the manufacturing process of the organic light emitting display panel 100, most functional film layers are formed by using a light-transmitting material, and generally, only the positions of the reflective electrode, the signal routing line, and the like of the organic light emitting diode device are manufactured by using a light-proof material, and these light-proof parts are all concentrated in the organic light emitting diode device and the area near the organic light emitting diode device, and the spacing area of the organic light emitting diode device, that is, the non-pixel setting area, has light-transmitting property. In the display device provided in the embodiment of the present invention, the occupied area of each sub-pixel included in the first display area 11, in which the organic light emitting display panel is disposed in the same unit area, is smaller than the occupied area of each sub-pixel included in the second display area 12, so that the occupied area of the non-pixel disposed area in the first display area 11 can be increased, and the first display area 11 has a larger area of the light transmission area compared with the second display area 12, thereby obtaining higher light transmission, and external ambient light can reach the inside of the display panel through the non-pixel disposed area of the first display area 11. Further, in the display device provided in the embodiment of the present invention, the photosensitive element and the indicator light are disposed on a side away from the light emitting surface of the first display area 11, as shown in fig. 1, the photosensitive element 200 and the indicator light 300 can be disposed on the back of the first display area 11 opposite to the organic light emitting display panel 100, and the area of the light transmitting area of the first display area 11 is relatively large, so that the photosensitive element 200 can fully receive the ambient light through the first display area 11 to perform a photosensitive function; the light that pilot lamp 300 sent also can pass through first display area 11 and outwards effectively be emergent, from this no longer need be for photosensitive element 200 when making organic light emitting display panel 100, the positions are reserved to components such as pilot lamp 300, but the pixel arrangement mode of the display area that photosensitive element 200 and pilot lamp 300 correspond is rationally adjusted, make this display area have higher transmittance, thereby can set up photosensitive element and pilot lamp and be located organic light emitting display panel's back, realize organic light emitting display panel's comprehensive screen display, the screen that has further improved the display screen accounts for the ratio.
In an implementation, the first display area 11 and the second display area of the organic light emitting display panel are distributed as shown in fig. 2. The first display area 11 may be located at the top of the display panel for displaying simple information such as time, weather, operators, power consumption, and the like, and the light sensing element, the indicator light, and other elements may be disposed at the back of the first display area 11 relative to the organic light emitting display panel 100. The second display area 12 may be a high resolution display area for displaying images, and the pixel arrangement manner of the second display area 12 may be any pixel arrangement manner in the prior art, and the resolution thereof may also reach the resolution of any display panel in the prior art, which is not limited herein. The photosensitive element 200 may be one or more of a camera, a facial recognizer and a light intensity sensor. In addition, other components with photosensitive function may be included, which is not limited herein.
In order to improve the transmittance of the first display region 11 of the organic light emitting display panel, the following pixel arrangements are provided in the embodiments of the present invention, which are illustrated in the following examples, but not all embodiments of the present invention are provided, and other modifications based on the inventive concept of the present invention are within the scope of the present invention.
In a practical manner, the pixel arrangement structure of the organic light emitting display panel provided by the embodiment of the invention is as shown in fig. 3, a pitch d1 between sub-pixels 111 in each pixel unit P11 in the first display area 11 is equal to a pitch d2 between sub-pixels 121 in each pixel unit P12 in the second display area 12; and the pitch between the adjacent pixel cells P11 in the first display region 11 is greater than the pitch between the adjacent pixel cells P12 in the second display region.
The pitch between adjacent pixel units may be a pitch between adjacent pixel units along a row direction, or a pitch between adjacent pixel units along a column direction. Taking the pixel structure shown in fig. 3 as an example, a pitch w1 between adjacent pixel cells P11 in the first display region in the row direction is equal to a pitch w2 between adjacent pixel cells P12 in the second display region, and a pitch h1 between adjacent pixel cells P11 in the first display region in the column direction is greater than a pitch h2 between adjacent pixel cells P12 in the second display region.
In the above-mentioned pixel arrangement structure, the pitches of the sub-pixels inside each pixel of the first display area 11 and the second display area 12 of the organic light emitting display panel are equal, so that the light emitting effect of each pixel as a light emitting unit is substantially the same, and then the overall display effect of the first display area 11 and the second display area 12 is close. Meanwhile, the distance between the adjacent pixel units P11 in the first display area 11 is increased, which can increase the area of the light-transmitting region of the first display area 11, thereby being more beneficial to the light sensing of the light sensing element 200 located behind the first display area 11, realizing the full-screen display of the organic light emitting display panel 100, and further improving the screen occupation ratio of the display screen.
In addition to the pixel arrangement structure shown in fig. 3, in a specific implementation, the pixel arrangement structure shown in fig. 4 may be adopted, where a pitch d1 between the sub-pixels 111 in each pixel unit P11 of the first display area 11 is equal to a pitch d2 between the sub-pixels 121 in each pixel unit P12 of the second display area 12; a pitch w1 between adjacent pixel cells P11 in the first display region 11 in the row direction is greater than a pitch w2 between adjacent pixel cells P12 in the second display region 12, while a pitch h1 between adjacent pixel cells P11 in the first display region 11 in the column direction is greater than a pitch h2 between adjacent pixel cells P12 in the second display region 12.
The distance between the adjacent pixel units P11 in the first display area 11 is increased in both the row direction and the column direction, so that the area of the light-transmitting area of the first display area 11 can be further increased, which is beneficial to the light sensing of the light sensing element 200.
In addition, in practical implementation, a pixel arrangement structure as shown in fig. 5 may also be adopted, as shown in fig. 5, the number of sub-pixels 111 included in the first display area 11 per unit area is equal to the number of sub-pixels 121 included in the second display area 12; the size of the sub-pixel 111 in the first display region 11 is smaller than the size of the sub-pixel 121 in the second display region 12.
As shown in fig. 5, the pitch d1 between the sub-pixels 111 in each pixel unit P11 of the first display region 11 is equal to the pitch between the sub-pixels 121 in each pixel unit P12 of the second display region 12, and the pitch h1 between the adjacent pixel units in the first display region 11 is increased by reducing the size of the sub-pixels of the first display region 11. As can be seen from fig. 5, the number of the pixel units (and the sub-pixels) included in the unit area of the first display area 11 and the second display area 12 is equal, so that the first display area 11 and the second display area 12 have the same PPI (pixel Per inch), and by adopting the pixel arrangement structure, the area of the light-transmitting region of the first display area 11 can be increased without reducing the PPI of the display panel, so that the photosensitive element 200 located behind the first display area 11 has a better photosensitive effect, and the first display area 11 can also have a better display effect.
In another implementation manner, the pixel arrangement structure of the organic light emitting display panel provided by the embodiment of the invention is as shown in fig. 6, wherein a pitch between adjacent pixel units P11 in the first display area 11 is equal to a pitch between adjacent pixel units P12 in the second display area 12; the spacing d1 between the sub-pixels 111 in each pixel unit P11 of the first display region 11 is greater than the spacing d2 between the pixels 121 in each pixel unit P12 of the second display region 12.
The pitch between adjacent pixel units may be a pitch between adjacent pixel units along a row direction, or a pitch between adjacent pixel units along a column direction. Taking the pixel structure shown in fig. 6 as an example, a pitch w1 between adjacent pixel cells P11 in the first display region 11 is equal to a pitch w2 between adjacent pixel cells P12 in the second display region 12 along the row direction, and a pitch h1 between adjacent pixel cells P11 in the first display region 11 is also equal to a pitch h2 between adjacent pixel cells P12 in the second display region 12 along the column direction.
On the premise of ensuring equal spacing between adjacent pixel units in the first display area 11 and the second display area 12, increasing the spacing between the sub-pixels 111 inside the pixel unit of the first display area 11 can be achieved by the following two ways: firstly, on the premise of not increasing the size of a pixel unit, the size of each sub-pixel is reduced to obtain a larger distance between the sub-pixels, so that the light transmittance of the first display area 11 is improved; secondly, on the premise of not reducing the size of the sub-pixels, the size of the pixel unit is increased, so that the sub-pixels have a larger interval therebetween, and the area of the light-transmitting area of the first display area 11 is increased.
In practical applications, the high PPI display panel minimizes the pitch between the pixel units and between the sub-pixels inside the pixel units during the manufacturing process to obtain a larger number of pixel units in a unit area, which also results in a lower transmittance of such a display area. When the first pixel arrangement structure is adopted, the PPI of the first display region 11 is not reduced, and the area of the light-transmitting region of the first display region 11 can be increased; however, as the size of the sub-pixels is further reduced, the difficulty of the manufacturing process increases for the display panel having the originally higher PPI. When the second pixel arrangement structure is adopted, the requirement for PPI is not high because the first display region 11 corresponds to the display region where the photosensitive element 200 and the indicator 300 are disposed, and the display region is usually used for displaying simpler images. The PPI of the first display region 11 is reduced to obtain higher transmittance of the first display region 11, so as to meet the photosensitive requirement of the photosensitive element, and simultaneously achieve higher screen occupation ratio of the display screen. And the sub-pixels in the first display area 11 and the second display area 12 have the same size, so that the problem of difficulty increase of the sub-pixel manufacturing process is avoided.
For example, fig. 6 and 7 show two pixel arrangement structures of the first display area 11, in which the size of the sub-pixel 111 in the first display area 11 is equal to the size of the sub-pixel 121 in the second display area 12; and the number of sub-pixels 111 included in the first display region 11 per unit area is smaller than the number of sub-pixels 121 included in the second display region 12. The PPI of the first display region 11 shown in fig. 7 is higher than the PPI of the first display region 11 shown in fig. 6, and the transmittance of the first display region 11 shown in fig. 6 is greater than the transmittance of the first display region 11 shown in fig. 7. As shown in fig. 6, the first display area 11 and the second display area 12 are still sub-pixels of the same color in the column direction, and the size of the pixel unit of the first display area 11 is 2 times that of the pixel unit of the second display area 12. As shown in fig. 7, the colors of the sub-pixel columns in the column direction of the first display area 11 and the second display area 12 are not exactly the same, but the size of the pixel units of the first display area 11 is 1.8 times the size of the pixel units of the second display area 12. In a specific implementation, the pixel arrangement mode may be selected according to an actual situation, and is not limited herein.
In another implementation manner, the pixel arrangement structure of the organic light emitting display panel provided by the embodiment of the invention is as shown in fig. 8, wherein a pitch between adjacent pixel units P11 in the first display area 11 is greater than a pitch between adjacent pixel units P12 in the second display area 12; the pitch d1 between the sub-pixels 111 in each pixel unit P11 of the first display region 11 is greater than the pitch d2 between the pixels 121 in each pixel unit P12 of the second display region 12.
Similarly, the pitch between adjacent pixel units may be a pitch between adjacent pixel units in the row direction or a pitch between adjacent pixel units in the column direction. Taking the pixel structure shown in fig. 8 as an example, a pitch w1 between adjacent pixel cells P11 in the first display region 11 in the row direction is greater than a pitch w2 between adjacent pixel cells P12 in the second display region 12, and a pitch h1 between adjacent pixel cells P11 in the first display region 11 in the column direction is greater than a pitch h2 between adjacent pixel cells P12 in the second display region 12. Taking the pixel structure shown in fig. 9 as an example, a pitch w1 between adjacent pixel cells P11 in the first display region 11 in the row direction is equal to a pitch w2 between adjacent pixel cells P12 in the second display region 12, and a pitch h1 between adjacent pixel cells P11 in the first display region 11 in the column direction is greater than a pitch h2 between adjacent pixel cells P12 in the second display region 12. In a specific implementation, the area of the light-transmitting region in the first display region may also be increased by increasing the distance between adjacent pixel units in the row direction, which is not limited herein.
By adopting the above pixel arrangement mode, the space between the pixel units in the first display area 11 and the space between the sub-pixels in the pixel units are increased, and the area of the light transmission area of the first display area 11 can be increased to the greatest extent, so that the light transmission of the first display area 11 is improved, and the higher the light transmission of the first display area 11 is, the better the light sensing condition of the light sensing element 200 behind the first display area 11 is, which is beneficial to improving the light sensing quality of the light sensing element 200.
Further, as shown in fig. 8 and 9, in the present embodiment, the number of sub-pixels 111 included in the first display region 11 per unit area is smaller than the number of sub-pixels 121 included in the second display region 12; the size of the sub-pixel 111 in the first display region is smaller than the size of the sub-pixel 121 in the second display region. By reducing the size of the sub-pixels in the first display region 11, a larger pitch between adjacent pixel units can be obtained in the column direction, thereby improving the transmittance of the first display region 11 to a greater extent. However, the pixel structure shown in fig. 8 may obtain higher transmittance of the first display region 11 than the pixel structure shown in fig. 9, but the pixel structure shown in fig. 9 has higher PPI than the pixel structure shown in fig. 9, so that in practical applications, a suitable pixel arrangement mode may be selected by considering transmittance and pixel resolution comprehensively, and is not limited herein.
The transmittance of the first display region 11 will be specifically described with reference to three pixel arrangement structures shown in fig. 5, 6 and 8. When the pixel arrangement structure shown in fig. 5 is employed, the size of the sub-pixel 111 of the first display area 11 is 1/4 of the size of the sub-pixel 121 of the second display area 12, then the transmittance of the first display area 11 can be improved by 75% in the case where the pitches between the adjacent pixel units are equal; when the pixel arrangement structure shown in fig. 6 is employed, the PPI of the first display region 11 is 1/3 of the PPI of the second display region 12, whereby the transmittance of the first display region 11 may be increased by 76%; when the pixel arrangement structure shown in fig. 8 is employed, the PPI of the first display region 11 is 1/3 of the PPI of the second display region 12, while the size of the sub-pixel 111 of the first display region 11 is 1/4 of the size of the sub-pixel 121 of the second display region 12, whereby the transmittance of the first display region 11 can be improved to 92%. In practical application, the size of the sub-pixel and the PPI display are in a mutual restriction relationship with the display effect, and the smaller the size of the sub-pixel is, the lower the PPI display is, the lower the display resolution of the region is, and the poorer the display effect is; the reduction of the sub-pixel size and the reduction of the display PPI are also beneficial to improving the transmittance of the region, and the higher the transmittance is, the better the photosensitive condition of the photosensitive element behind the region is, so in practical application, the display effect and the transmittance need to be considered comprehensively to set a proper pixel size and display the PPI. Experiments of the present invention with various pixel arrangement structures shown in fig. 3-9 prove that a better transmittance of the first display region 11 can be obtained by setting the size of the sub-pixel 111 in the first display region 11 to be within the range of 1/4-1/2 of the size of the sub-pixel 121 in the second display region 12, and the display effect level meets the actual use requirement. However, as the process advances, the case of manufacturing an organic light emitting diode device with higher luminance or implementing a finer process to make the sub-pixel size beyond the above range also falls within the scope of the present invention, and is not particularly limited herein.
Since the pixel arrangement structures of the first display area and the second display area are different, the driving modes of the two display areas can be correspondingly adopted in various modes. For example, as shown in the pixel arrangement structure of fig. 3, 5, 6 and 8, the sub-pixels of the same color in the first display area 11 and the second display area 12 are arranged in a plurality of rows, and the sub-pixels of each row in the first display area 11 are aligned with the corresponding sub-pixel rows of the same color in the second display area 12.
As for the above-described pixel arrangement structure, as shown in fig. 10 and 11, the organic light emitting display panel 100 further includes: a plurality of data signal lines 13 extending in the subpixel column direction; the number of the data signal lines 13 is equal to the number of the sub-pixels 121 included in each sub-pixel row in the second display area; the sub-pixels in the first display area 11 and the sub-pixels in the second display area 12 in the same column share the same data signal line; and the lengths of the data signal lines 13 are equal. In the embodiment of the present invention, the sub-pixels in the same column of the first display area 11 and the second display area 12 share the data signal line 13, and there is no need to provide a data signal line for each of the first display area 11 and the second display area 12, so that the area of the display area occupied by the data signal line can be reduced. In order to improve the transmittance of the first display region 11, there may be a case where the first display region 11 includes less sub-pixel columns than the second display region (as shown in fig. 5, 6 or 8), and at this time, the data signal lines 13 are kept to have the same length, so that the load difference between the data signal lines caused by the unequal number of sub-pixels connected to the data signal lines can be reduced to a certain extent, which is beneficial to improving the display effect.
For the pixel arrangement of the organic light emitting display panel shown in fig. 4, 7 and 9, the color of the sub-pixels in the same column in the first display area 11 is different from that in the second display area 12, or the color of the sub-pixel columns in the same first display area 11 is not aligned with that of the sub-pixel columns in the same second display area 12, and at this time, the corresponding sub-pixel columns may still share the same data signal line. For example, as shown in fig. 4, the data signal lines may be deformed at the boundary position between the first display area 11 and the second display area 12, so that the same data signal line can be shared by the sub-pixel columns of the same color; in contrast, in the case shown in fig. 7 and 9, the sub-pixels in the same column may share the same data signal line, and the output data signal may be converted at the driver chip side during driving.
In addition, as shown in fig. 10 and 11, the organic light emitting display panel 100 further includes: the gate driving circuit 14 is located at a side of the display panel, and the driving chip 15 (driving IC) is located at a bottom of the display panel, and the gate driving circuit 14 is matched with the driving chip 15 to output data signals to each row of sub-pixels in a time division manner, so that driving display of the organic light emitting display panel can be realized. Fig. 10 and 11 show that the first display region 11 and the second display region 12 adopt the same driving manner of the gate driving circuit, in practical applications, the first display region 11 and the second display region 12 can also adopt two sets of gate driving circuits independent of each other for driving, referring to fig. 12, each row of sub-pixels in the first display region 11 is connected to the gate driving circuit 141 through one gate line, and each row of sub-pixels in the second display region 12 is connected to the gate driving circuit 142 through one gate. When the gate driving circuits are provided in the first display region 11 and the second display region 12, respectively, different images or images with different resolutions can be displayed on the same display device. The driving frequency for each display area in the display panel may also be different, for example, for the first display area 11, the driving frequency is used to display simple images such as time, weather, and electric quantity, and the variation of the displayed images is small, so a low-frequency driving mode may be adopted; since the second display area 12 is used to display high-resolution image quality, an image with high image quality can be displayed by high-frequency driving.
In practical applications, as shown in fig. 13, the display device provided in the embodiment of the present invention further includes: a protective cover 400 on a side of the organic light emitting display panel 100 facing away from the photosensitive elements 200 and the indicator 300, a main board 500 and a battery 600 on a side of the second display area 12 facing away from the protective cover 100, and a protective rear case 700 on a side of the main board 500 facing away from the organic light emitting display panel 100. The photosensitive element 200 and the indicator 300 may be connected to the main board 500 and driven by the main board. A bracket for placing the main board 500, the battery 600, and the like may be provided on the protective rear case 700. The protective cover 400 may be a glass cover or the like.
In addition, since the pixel arrangement structures of the first display area 11 and the second display area 12 are different, in order to achieve a better display effect, an embodiment of the present invention further provides a display method based on any one of the above display devices, which may specifically include the following two aspects:
on one hand, since the pixel arrangement structures of the first display area 11 and the second display area 12 are different, the sub-pixel size of the first display area 11 may be smaller than that of the second display area 12; the display PPI of the first display region 11 may be smaller than that of the second display region 12, and therefore, when the first display region 11 and the second display region 13 are displayed simultaneously, in order to ensure the uniformity of the display luminance of the first display region 11 and the second display region 12, the driving signal of the first display region 11 needs to be adjusted accordingly. For example, when the first display area 11 and the second display area 12 adopt the circuit structure as shown in fig. 10 or fig. 11, the driving current of each pixel unit in the first display area 11 can be increased, so that the overall display brightness of the first display area 11 is consistent with the overall display brightness of the second display area 12; on the other hand, if the first display area 11 and the second display area 12 adopt the circuit structure as shown in fig. 12, since the two display areas are driven separately, it is possible to extend the light emitting time of the first display area 11 in the same period by increasing the duty ratio of the light emitting control signal for the first display area 11, so that the overall display luminance of the first display area 11 and the second display area 12 is the same.
On the other hand, since the photosensitive element needs to receive the ambient light or the light emitted from the object to be measured for image processing, it is necessary to control each pixel unit in the first display region 11 to be in a dark state when the photosensitive element 200 is in an operating state in order to avoid interference of the light emitted from the display panel with the photosensitive element. The light emission and the light emission color of the indicator light 300 are less affected by the image display of the first display area 11, and in practical applications, the appropriate color can be selected and the indicator light 300 has a strong light emission brightness, so that the influence of the first display area 11 on the light emission can be weakened.
For the above-mentioned adjustment of the light emission of each sub-pixel of the first display area 11, which involves the pixel circuit connected to the sub-pixel, taking the pixel circuit structure shown in fig. 14 as an example, the pixel circuit at least includes: a first thin film transistor M1, an initialization thin film transistor M2, a second thin film transistor M3, a driving thin film transistor M4, and an organic light emitting diode OLED; the source of the initialization thin film transistor M2 is generally connected to the reference signal line VREF, and is configured to initialize the gate of the driving thin film transistor M4 by using the reference potential of the reference signal line VREF when the driving thin film transistor M2 is in a conducting state under the control of the first scanning signal line S1; the source of the first thin film transistor M1 is commonly connected to the data signal line VDATA, and is used for writing the data signal of the data signal line VDATA into the source of the driving thin film transistor M4 when the first thin film transistor M1 is turned on under the control of the second scanning signal line S2; the source of the second thin film transistor M3 is generally connected to the power supply voltage signal line PVDD, and is used for writing a power supply signal supplied from the power supply voltage signal line PVDD to the source of the driving thin film transistor M4 when the second thin film transistor M3 is in an on state under the control of the emission control line EMIT.
Further, the pixel circuit further includes: a light emission controlling thin film transistor M5; the gate of the light emitting control thin film transistor M5 is connected to a light emitting control line EMIT, the source is connected to the drain of the driving thin film transistor M4, and the drain is connected to the organic light emitting diode OLED. When the light emitting control thin film transistor M5 is in a conducting state under the control of the light emitting control line EMIT, the drain of the driving thin film transistor M4 is conducted with the organic light emitting diode OLED. That is, when the light emitting control tft M5 is turned on under the control of the light emitting control line EMIT, a path is formed between the power voltage signal line PVDD and the other power voltage signal line PVEE, and the magnitude of the current in the circuit determines the magnitude of the OLED display luminance. Therefore, in the first display area 11, the driving current of each sub-pixel can be adjusted by controlling the data signal of the sub-pixel, so as to achieve the purpose of adjusting the light emitting brightness of the sub-pixel.
The invention provides a display device and a display method thereof, the display device comprises an organic light-emitting display panel 100, a photosensitive element 200 and an indicator light 300; the organic light emitting display panel 100 includes a first display region 11 and a second display region 12, and the light sensing element 200 and the indicator light 300 are located at a side away from a light emitting surface of the first display region 11; wherein the first display area 11 and the second display area 12 each include: a plurality of pixel units; each pixel unit comprises a plurality of sub-pixels; the occupied area of the sub-pixels of the first display region 11 is smaller than the occupied area of the sub-pixels of the second display region 12 in a unit area. The area of the light-transmitting area of the first display area 11 is increased by reducing the occupied area of the sub-pixels in the first display area 11, so that the photosensitive element 200 on the backlight side of the first display area 11 can sufficiently receive the ambient light through the first display area 11 to perform a photosensitive function; the light emitted by the indicator light 300 can also be effectively emitted outwards through the first display area 11, so that the positions of the photosensitive element 200, the indicator light 300 and other elements are not required to be reserved when the organic light-emitting display panel 100 is manufactured, the comprehensive screen display of the organic light-emitting display panel 100 is realized, and the screen occupation ratio of the display screen is further improved.
