Detailed Description

The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.

In the OLED display substrate, a plurality of pixel driving circuits and light-emitting devices connected with the pixel driving circuits are arranged on a substrate, each light-emitting device comprises an anode, a light-emitting material layer and a cathode, and when the anodes and the cathodes of the light-emitting devices are made of light-transmitting materials, the whole OLED display substrate can have certain light transmittance. With the increasing screen occupation of mobile phones, hiding the front camera below the screen gradually becomes the key direction for the current mobile phone display screen development. Accordingly, in order to further improve the light transmittance of the display screen, in some embodiments, a portion of the pixel driving circuit and the light emitting device in a region of the display substrate opposite to the camera head is removed.

Fig. 1A is a schematic view of a region distribution of a display substrate in the related art, fig. 1B is a schematic view of a pixel arrangement in the related art, and fig. 1C is a schematic view of another pixel arrangement in the related art. As shown in fig. 1A to 1C, the transparent area TA is used to face a functional device such as a camera, and a normal display area AA is around the transparent area TA. The display substrate includes a plurality of effective sub-pixel groups 20g arranged in an array, each effective sub-pixel group 20g includes a plurality of effective sub-pixels 20e, for example, the plurality of effective sub-pixels 20e in each effective sub-pixel group 20g includes: two green subpixels G, one red subpixel R, and one blue subpixel B.

In order to improve the light transmittance of the light-transmitting area TA, in one embodiment, the pixel driving circuits in the effective subpixel groups 20g of odd columns in the light-transmitting area TA are removed, thereby obtaining the structure shown in fig. 1B. In other embodiments, in each row of effective sub-pixel groups 20g, a partial number of pixel driving circuits in the effective sub-pixel group 20g are periodically removed, so that the pixel driving circuits in the effective sub-pixel groups 20g of two adjacent rows in the remaining effective sub-pixel groups 20g are distributed alternately, as shown in fig. 1C. Illustratively, the position of the pixel driving circuit is removed as the dummy sub-pixel 20v, wherein the light emitting unit may no longer be disposed in the dummy sub-pixel 20 v; alternatively, a light emitting unit may be disposed in the vacant sub-pixel 20v, and a pixel driving circuit connected to the light emitting unit is disposed in a transition region between the light transmissive region TA and the normal display region, so as to be connected to the light emitting unit through a wiring.

However, in both of the pixel arrangements shown in fig. 1B and 1C, light is severely diffracted when passing through the vacant sub-pixel 20v, resulting in ghost images taken by the camera.

An embodiment of the present disclosure provides a display substrate, and fig. 2 is a schematic pixel arrangement diagram of the display substrate provided in some embodiments of the present disclosure, and as shown in fig. 2, the display substrate includes a light transmissive area TA and a normal display area (i.e., an area around the light transmissive area TA in fig. 2), and a positional relationship between the normal display area and the light transmissive area TA may be the same as that in fig. 1A. The normal display area and the light transmission area TA each include a plurality of sub-pixels arranged in an array. The sub-pixels in the regular display area are all active sub-pixels 20e, for example, a first color sub-pixel, a second color sub-pixel, and a third color sub-pixel. The plurality of effective sub-pixels 20e in the normal display area form a plurality of effective sub-pixel groups 20g arranged in an array, each effective sub-pixel group 20g comprises 2 × 2 effective sub-pixels 20e, wherein the first color sub-pixels and the third color sub-pixels are arranged in the same column, and the two second color sub-pixels are arranged in the same column. In the embodiments of the present disclosure, the first color sub-pixel is a red sub-pixel R, the second color sub-pixel is a green sub-pixel G, and the third color sub-pixel is a blue sub-pixel B.

It should be noted that a pixel driving circuit is disposed in the effective sub-pixel 20e (for example, the pixel driving circuit adopts a structure of 7T1C, that is, includes 7 transistors and 1 capacitor), each pixel driving circuit is connected to a light emitting unit, and the red sub-pixel R (or the green sub-pixel G or the blue sub-pixel B) means that light emitted by the light emitting unit connected to the pixel driving circuit in the effective sub-pixel 20e is red light (or green light or blue light).

Fig. 3 is a schematic diagram of the pixel arrangement of the light-transmitting area in fig. 2, in which one part of the sub-pixels in the light-transmitting area TA is an effective sub-pixel 20e, and the other part is a blank sub-pixel 20 v. The plurality of active sub-pixels 20e form a plurality of rows of active sub-pixel groups 20g, each row of the plurality of rows of active sub-pixel groups 20g includes a plurality of active sub-pixel groups 20g, and each of the plurality of active sub-pixel groups 20g includes a plurality of active sub-pixels 20 e. Any two adjacent effective sub-pixel groups 20g in the same row are separated by the main spacer 10, wherein any two adjacent effective sub-pixel groups 20g in the same row may be separated by a part of the main spacer 10 or may be separated by the main spacer 10 as a whole. The main spacer 10 includes at least two sub-spacers (e.g., a first sub-spacer 11 and a second sub-spacer 12) arranged in a column direction, and the sub-spacers may include at least one vacant sub-pixel 20 v. All the sub-partitions of the plurality of partitions 10 are arranged in a plurality of rows. The widths of at least two sub-interval parts arranged along the row direction are different; and/or the width of at least two sub-partitions in one and the same main partition 10 is different. In the embodiment of the present disclosure, the row direction is the left-right direction in fig. 2, and the column direction is the up-down direction in fig. 2. In some specific examples, the widths of any two adjacent sub-spacers arranged in the row direction are different; and/or the width of any two adjacent sub-partitions in the same main partition 10 is different. It should be understood that two adjacent sub-spacers means that there is no other sub-spacer between the two sub-spacers.

It should be noted that, in the embodiment of the present disclosure, the main spacer 10 and the vacant sub-pixel 20v do not mean that any structure is not provided, but some layers with high light transmittance, such as a planarization layer, a pixel defining layer, an insulating layer such as a gate insulating layer, and even a light emitting layer, a hole injection layer, a hole transport layer, and the like in a light emitting device may be provided. Even the relevant devices (e.g. thin film transistors, capacitors) in the pixel drive circuit can be provided for the vacant sub-pixels 20v close to the regular display area.

In the embodiment of the present disclosure, each sub-spacer corresponds to a light-transmitting slit, and the display substrate can be regarded as a grating composed of multiple slits. Fig. 4 is a diagram showing a light intensity distribution diagram of single slit diffraction, multiple beam interference, and multiple slit diffraction, fig. 4 (a) is a diagram showing a light intensity distribution diagram of single slit diffraction, fig. 4 (b) is a diagram showing a light intensity distribution diagram of multiple beam interference, and fig. 4 (c) is a diagram showing a light intensity distribution diagram of grating diffraction. As shown in fig. 4, the multi-slit diffraction is a common result of the interference and the single-slit diffraction, and the light intensity distribution formula of the multi-slit diffraction is shown in formula (1):

wherein the content of the first and second substances,

a is the width of the slit and d is the period of the slit, i.e., the center-to-center spacing of adjacent slits. I is the light intensity, I₀The intensity of light in the zero diffraction order.

Is a single-slit diffraction factor, and the diffraction factor is,

is a multi-slit interference factor. From the above formula, the light intensity distribution of single slit diffraction is only related to the property of the single slit, the light intensity distribution of multi-slit interference is related to the periodic arrangement of the slits, and the light intensity distribution of multi-slit diffraction is related to the width and the distribution period of the slits.

Fig. 5 is a graph comparing diffraction intensity of light when the pixel arrangement of the embodiment of the present disclosure and the pixel arrangement of fig. 1B are used, and as shown in fig. 5, the horizontal axis represents diffraction angle (in radians) and the vertical axis represents light intensity. In the embodiment of the present disclosure, the widths of the plurality of sub-spacers arranged in the row direction are not completely the same, and/or the widths of two adjacent sub-spacers 11 and 12 in the same main spacer 10 are not the same. Therefore, compared with the pixel arrangement mode shown in fig. 1B and fig. 1C, when the display substrate provided by the embodiment of the disclosure is subjected to multi-slit diffraction, more bright stripes or bright rings appear, and the total energy of light is constant, so that the brightness of the bright stripes outside the central stripe is reduced, the diffraction intensity is reduced, and the imaging effect of the camera is improved.

Fig. 6 is a comparison diagram of imaging effects when different pixel arrangement modes are adopted, and fig. 6 (a) is a schematic diagram of the imaging effect of the camera when the pixel arrangement mode of fig. 1B is adopted; (b) the figure is a schematic diagram of the imaging effect of the camera when the pixel arrangement mode of fig. 1C is adopted; (c) the image is a schematic diagram of the imaging effect of the camera when the pixel arrangement mode of fig. 3 is adopted, and it can be seen through comparison that the imaging effect of the camera is clearer when the pixel arrangement mode provided in the embodiment of the present disclosure is adopted.

In some embodiments, as shown in fig. 3, the plurality of active subpixels 20e in the active subpixel group 20g are arranged in two rows. For example, the effective sub-pixel group 20g includes four effective sub-pixels 20e, which are: a red sub-pixel R, a blue sub-pixel B and two green sub-pixels G, wherein the four active sub-pixels 20e are arranged in two rows and two columns, the red sub-pixel R and the blue sub-pixel B are arranged in one column, and the two green sub-pixels are arranged in one column. In two adjacent effective sub-pixel groups 20G arranged along the row direction, the positions of the green sub-pixels G are the same and are both right-side columns; the red sub-pixel R is located at the same position, and the blue sub-pixel B is located at the same position. Of course, the positions of the red sub-pixel R and the blue sub-pixel B in the two adjacent effective sub-pixel groups 20g may be interchanged, that is, the position of the red sub-pixel R in one effective sub-pixel group 20g is the same as the position of the blue sub-pixel B in the other effective sub-pixel group 20 g. The position of one effective subpixel 20e is the position of the effective subpixel 20e in the effective subpixel group 20 g.

The main partition portion 10 includes: the first sub-spacer 11 and the second sub-spacer 12, and the first sub-spacer 11 and the second sub-spacer 12 in at least one main spacer 10 are disposed in the same row as the two adjacent rows of the effective sub-pixel groups 20 g. The width of the first sub-spacers 11 is 2 to 6 times the width of the second sub-spacers 12. For example, as shown in fig. 3, each effective sub-pixel group 20g includes 2 × 2 effective sub-pixels 20e, the first sub-interval part 11 in the main interval part 10 includes 2 × 6 absent sub-pixels 20v, and the second sub-interval part 12 in the main interval part 10 includes 2 × 2 absent sub-pixels 20 v. That is, the width of the first sub-spacer 11 is 3 times the width of the effective sub-pixel group 20 g. For another example, each effective sub-pixel group 20g includes 2 × 4 effective sub-pixels 20e, the first sub-interval part 11 in the main interval part 10 includes 2 × 10 absent sub-pixels 20v, and the second sub-interval part 12 in the main interval part 10 includes 2 × 2 absent sub-pixels 20 v. That is, the width of the first sub-spacer 11 is 5 times the width of the effective sub-pixel group 20 g.

It should be noted that the "width" of the sub-spacer (or other structure) in the embodiments of the present disclosure refers to the dimension of the sub-spacer (or other structure) in the row direction.

Two adjacent effective sub-pixel groups 20g in the same row are spaced apart by the main spacer 10. The main partition 10 includes a first sub-partition 11 and a second sub-partition 12. A plurality of effective sub-pixels 20e are provided between at least two adjacent main spacers 10 arranged in the column direction; also, at least two main spacers 10 aligned in the column direction may be adjacent. At least one main partition 10 is in an axisymmetric pattern or a centrosymmetric pattern. Illustratively, each main partition 10 is an axisymmetric pattern or a centrosymmetric pattern.

Unlike the arrangement shown in fig. 3, in fig. 7, the red sub-pixel R and the blue sub-pixel B in the effective sub-pixel group 20G are arranged in a column, two green sub-pixels G are respectively located at two sides of the column where the red sub-pixel R and the blue sub-pixel B are located, and the two green sub-pixels G are respectively arranged with the red sub-pixel R and the blue sub-pixel B along the row direction.

In fig. 7, the first sub-spacer 11 and the second sub-spacer 12 are provided in the same row as the two rows of effective sub-pixels 20e, and the width of the first sub-spacer 11 is 2 to 6 times the width of the second sub-spacer 12. For example, the second sub-interval part 12 in each main interval part 10 includes one vacant sub-pixel 20v, the first sub-interval part 11 includes 3 vacant sub-pixels 20v, and the width of the first sub-interval part 11 is 3 times the width 12 of the second sub-interval part.

Alternatively, any two adjacent main spacers 10 arranged in the row direction are centrosymmetric, and any two adjacent effective subpixel groups 20g arranged in the row direction are mirror-symmetric in shape.

Fig. 8 is a schematic diagram of pixel arrangement in a light-transmitting region according to another embodiment of the disclosure, and the pixel arrangement shown in fig. 8 is similar to that shown in fig. 7, except that the positions of the red sub-pixel R, the green sub-pixel G, and the blue sub-pixel B in the effective sub-pixel group 20G in fig. 8 are different from those in fig. 7. As shown in fig. 8, in the effective sub-pixel group 20G, two green sub-pixels G are located in the same column, a red sub-pixel R and a blue sub-pixel B are respectively located at two sides of the column where the green sub-pixel G is located, the red sub-pixel R and one of the green sub-pixels G are arranged along the row direction, and the blue sub-pixel B and the other green sub-pixel G are arranged along the row direction.

It should be noted that the pixel arrangement shown in the drawings of the present disclosure is just for illustration, and the arrangement of the light emitting unit connected to the pixel driving circuit may be different from the arrangement of the pixel driving circuit. Fig. 9A is a schematic distribution diagram of pixel driving circuits and light emitting units in the ith row of effective subpixel group in fig. 3, and fig. 9B is a schematic distribution diagram of pixel driving circuits and light emitting units in the ith row of effective subpixel group in fig. 8. Here, the light emitting unit includes the anode 22, the anode 22 includes a main body portion 221 and a connection portion 222 connected to the pixel driving circuit 21, and the position of the main body portion 221 of the anode 22 can be regarded as the position of the light emitting unit. As shown in fig. 9A and 9B, the pixel drive circuit 21 in each effective sub-pixel 20e is connected to a plurality of signal lines (not shown) including: a scan line, a data line, a first power line, a light emitting control line, a reset line, etc. In each effective sub-pixel group 20g, the pixel drive circuit 21r in the red sub-pixel overlaps with the body portion 221 of the anode 22 connected thereto in the thickness direction of the display substrate, the pixel drive circuit 21b in the blue sub-pixel overlaps with the body portion 221 of the anode 22 connected thereto, and for two green sub-pixels arranged in the column direction, the body portion 221 of the anode 22 connected to the pixel drive circuit 21g in one of the green sub-pixels overlaps with the pixel drive circuit 21g in the other green sub-pixel. It should be noted that the overlapping of the two structures means that the two structures overlap in the thickness direction of the display substrate.

Fig. 10 is a schematic view of pixel arrangement in a light-transmitting region according to other embodiments of the present disclosure, and as with the embodiment shown in fig. 7, in fig. 10, an effective sub-pixel group 20G includes one red sub-pixel R, one blue sub-pixel B, and two green sub-pixels G.

A plurality of effective sub-pixels 20e are disposed between at least two adjacent main spacers 10 (e.g., main spacers 101 and 102) arranged in the column direction.

Unlike the arrangement shown in fig. 7, in fig. 10, in two adjacent columns of main spacers 10, at least one main spacer 10 in one column overlaps with at least one main spacer 10 in the other column in the orthographic projection in the column direction, thereby being beneficial to improving the uniformity of display in the light-transmitting area.

The area ratio of the plurality of second sub spacers 15 in the transition region MA is smaller than the area ratio of the plurality of main spacers 10 in the light-transmitting region TA. For example, in the transition area MA, the area occupied by the second sub spacers 15 is x, and in the conventional display area AA, the area occupied by the main spacers 10 is y, and x < y. The transition area MA is configured to transition the display effect of the normal display area AA from the display effect of the transparent area TA. The transition area MA may be disposed on one side of the light-transmitting area TA, or disposed on at least two sides of the light-transmitting area TA.

Alternatively, at least one side of the light-transmitting area TA is provided with a plurality of transition areas MA arranged in a direction away from the light-transmitting area TA, and the effective sub-pixels 20e may not be provided between adjacent transition areas MA, or one or more rows of effective sub-pixels 20e may be provided. The areas of the plurality of transition regions MA located on the same side of the light-transmitting region TA are the same, and the farther away from the light-transmitting region TA, the smaller the area occupation ratio of the plurality of second sub spacers 15 in the transition regions MA; the closer to the light transmission region TA, the larger the area ratio of the plurality of second sub spacers 15 in the transition region MA. This makes the transition of the display effect between the light-transmitting area TA and the normal display area more gradual.

It should be noted that, in the above embodiments, the display substrate includes the light-transmitting area TA as an example, and in other embodiments of the disclosure, the whole area of the display substrate may be set as the light-transmitting area TA, so as to improve the light transmittance of the whole display substrate.

The reset lines RL to which the plurality of pixel driving circuits arranged in the row direction are connected may be the same, the scanning lines GL to which the plurality of pixel driving circuits arranged in the row direction are connected may be the same, and the emission control lines EM to which the plurality of pixel driving circuits arranged in the row direction are connected may be the same; the data lines DL connected to the plurality of pixel driving circuits arranged in the column direction are the same, and the first power lines VDD connected to the plurality of pixel driving circuits arranged in the column direction are the same.

In some embodiments, as shown in fig. 17A, each signal line is a straight line.

However, when the signal lines are made of metal material, if the signal lines directly pass through the main spacing portion, a certain diffraction effect of the light rays at the main spacing portion may be generated, and for this reason, in some embodiments, as shown in fig. 17B, at least one signal line includes a bending portion FL, and the bending portion FL is bent along the edge of the main spacing portion 10, so that a continuous light-transmitting region having an area as large as possible is formed at the position of the main spacing portion 10, so as to improve the diffraction of the light rays at the main spacing portion 10 as much as possible. In some examples, the bent portion FL is bent along an edge of the main compartment 10 and overlaps the main compartment 10; in other embodiments, the bent portion FL may be completely avoided from the main partition 10.

The embodiment of the present disclosure further provides a display device, which includes the display substrate in the above embodiment. The display device can be a product with a display function, such as a mobile phone, a tablet personal computer, a notebook computer, a television, transparent show window glass and the like.
