Compared with the prior art, the invention has the beneficial effects that:
1) when the display panel of the invention displays a static image on a full screen composed of the transparent display area, the non-transparent display area and the transition display area, the transition display area corresponding to the opening deviation range caused by the alignment deviation of the polaroid is dark. The dark area means that the brightness difference of each pixel in the area cannot be recognized by human eyes. The scheme can improve the user experience when the full-face screen is used.
2) In an alternative scheme, when a full screen composed of the transparent display area, the non-transparent display area and the transition display area displays a dynamic image together, the display gray value of each pixel in the transparent display area, the non-transparent display area and the transition display area is the original gray value of each pixel in the dynamic image. In other words, the original gray scale values of the pixels in the transition display region are not adjusted. The scheme can reduce the requirement on the data processing capacity of the drive chip, and simultaneously does not influence the user experience. The static image and the dynamic image can be identified according to the format of the file.
In other alternatives, when the full-screen composed of the transparent display area, the non-transparent display area and the transition display area displays the dynamic image together, the display gray value of each pixel in the transparent display area and the non-transparent display area is the original gray value of each pixel in the dynamic image, and the display gray value of each pixel in the transition display area is less than or equal to the original gray value of each pixel in the dynamic image. According to the scheme, when the dynamic image is displayed, the display gray value of each pixel in the transition display area is reduced, so that the experience of a user when the user uses the full-face screen is improved.
3) In an alternative, the display control method includes: acquiring an original static image; and keeping the original gray value of each pixel corresponding to the transparent display area and the non-transparent display area in the original static image unchanged, and reducing the original gray value of each pixel corresponding to the transition display area in the original static image to obtain a static image to be displayed for the transparent display area, the non-transparent display area and the transition display area to display.
In other words, the scheme obtains the static image to be displayed by performing brightness processing on the original static image. And providing data voltage for each pixel by the display gray value data of the static image to be displayed through the data signal channel of the display driving module. And the display driving module determines the driving voltage of each pixel in the transition display area according to the gamma curve of the transparent display area or the non-transparent display area.
In an alternative scheme, in the static image to be displayed, the ratio a) or b) of the display gray value of each pixel in the transition display area to the original gray value is fixed. Compared with the scheme b), the implementation method of the scheme a) is simple and low in cost.
Alternatively, the above ratio is 50% or less, 25% or less, or 10% or less. The original gray value can be reduced to less than half, less than one fourth, less than one tenth and the like according to specific products of the OLED substrate, and the brightness difference between the pixels cannot be recognized by human eyes.
The light-dark level of the dark area of the above alternative fluctuates with the initial light-dark level in the still image. In other alternatives, the gray scale value displayed by each pixel in the transitional display area can also be adjusted to 0. In other words, the brightness level of the dark region does not fluctuate with the initial brightness level in the still image, and always appears as a black region.
4) In an alternative, the display control method includes: acquiring original driving voltage corresponding to an original gray value of each pixel in an original static image; and keeping the original driving voltage of each pixel corresponding to the transparent display area and the non-transparent display area in the original static image unchanged, and reducing the original driving voltage of each pixel corresponding to the transitional display area in the original static image to obtain a group of driving voltages to be applied to each pixel in the transparent display area, the non-transparent display area and the transitional display area simultaneously.
Different from the scheme of adjusting the gray value, the scheme changes the size of the data voltage provided by the data signal channel to each pixel after the original gray value data of the original static image is sent to the display driving module.
Alternatively, a relationship curve of the to-be-applied driving voltage and the original driving voltage, which is applicable to each pixel of the transitional display region, may be stored in advance; and determining the driving voltage to be applied to each pixel of the transitional display area in the static image based on the relation curve. Each pixel adopts the same rule to obtain the driving voltage to be applied, and compared with the scheme that each pixel adopts different rules to obtain the driving voltage to be applied, the implementation method is simple and the cost is lower.
In an alternative, in the relationship curve, a ratio of a display gray value corresponding to the driving voltage to be applied to an original gray value corresponding to the original driving voltage is fixed. The scheme associates the gray-scale value with the driving voltage, and can realize the dark area with the same brightness degree no matter the gray-scale value or the driving voltage is adjusted.
The light-dark level of the dark area of the above alternative fluctuates with the initial light-dark level in the still image. In other alternatives, the driving voltage to be applied to each pixel in the transitional display area can be adjusted to turn off the driving transistor of the pixel. In other words, the brightness level of the dark region does not fluctuate with the initial brightness level in the still image, and always appears as a black region.
5) In the alternative, a) the transition display area is a closed ring around the transparent display area, the transition display area is a closed dark ring, or b) the transition display area is a non-closed ring around the transparent display area, the transition display area is a non-closed dark ring. In other words, the dark space may be a closed loop or a non-closed loop.
6) In an alternative, the transitional display area comprises a transparent display area extension area and a non-transparent display area extension area. The transparent display area extension area is connected with the transparent display area, the non-transparent display area extension area is connected with the non-transparent display area, the structure of the pixels of the transparent display area extension area is the same as that of the pixels of the transparent display area, and the structure of the pixels of the non-transparent display area extension area is the same as that of the pixels of the non-transparent display area. In other words, the offset range of the opening caused by the alignment deviation of the polarizer corresponds to the boundary offset range of the transparent display area and the non-transparent display area; when a static image is displayed, the area is set to be a dark area, so that the visual impact of the sudden change of brightness at the junction of the transparent display area and the non-transparent display area on human eyes can be reduced, and the user experience of the whole screen is improved.
7) The present invention also provides a cathode of a display panel, comprising: the display device comprises a first cathode and a second cathode surrounding the first cathode, wherein the first cathode and the second cathode are connected together, the first cathode is at least positioned in a transparent display area, the second cathode is at least positioned in a non-transparent display area, and the thickness of the first cathode is smaller than that of the second cathode. The first cathode and the second cathode are connected to facilitate the arrangement of the signal line.
8) The present invention also provides a mask blank set for manufacturing the cathode, comprising:
the first mask plate comprises a first frame and a first opening defined by the first frame, and the first opening corresponds to a transparent display area, a non-transparent display area and a transition display area between the transparent display area and the non-transparent display area;

The second cathode is manufactured by overlapping N mask plates in a grading manner, the connecting position of the N-1 connecting line on the N frame and the connecting position of the … … first connecting line on the second frame are different, the flatness of the second cathode close to the first cathode can be improved, the light transmittance difference is not large due to uneven thickness of the cathode, and the display effect is improved.

Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
FIG. 1 is a top view of a display panel according to an embodiment of the invention; fig. 2 is a sectional view taken along line AA in fig. 1. Fig. 3(a) is a state diagram when the display panel in fig. 1 displays a still image; fig. 3(b) is a state diagram when another display panel displays a still image.
Referring to fig. 1 to 3(b), the display panel 1 includes an OLED substrate 10 and a polarizer 11 disposed on the OLED substrate 10; the OLED substrate 10 comprises a transparent display area 101, a non-transparent display area 102 and a transition display area 103 located between the transparent display area 101 and the non-transparent display area 102, wherein the polarizer 11 is provided with an opening 11a, the polarizer 11 at least covers the non-transparent display area 102, the opening 11a at least exposes the transparent display area 101, and the size of the transition display area 103 is larger than or equal to the size of the alignment deviation of the polarizer 11;
when the transparent display area 101, the non-transparent display area 102 and the transitional display area 103 together display a still image, the transitional display area 103 is dark.
The alignment deviation of the polarizer 11 refers to the alignment deviation caused by the alignment precision in the horizontal direction when the polarizers 11 are attached to the corresponding OLED substrates 10 during the manufacturing of a batch of display panels 1. The misalignment of the polarizers 11 may cause the opening 11a of each polarizer 11 to expose the OLED substrate 10 differently.
FIG. 4 is a schematic cross-sectional structure diagram of a first OLED sub-pixel in a transparent display area. Referring to fig. 1 to 4, the transparent display region 101 includes a plurality of first OLED sub-pixels 1011, and each of the first OLED sub-pixels 1011 includes, from bottom to top: a light-transmissive anode 1011b formed on a light-transmissive substrate 1011a, a pixel defining layer 1011c having an opening, an OLED light-emitting material layer 1011d located within the opening, and a light-transmissive cathode 1011e located on the OLED light-emitting material layer 1011 d.
When a driving voltage is applied between the transparent anode 1011b and the transparent cathode 1011e of each first OLED subpixel 1011, the transparent display region 101 performs a display function; when no driving voltage is applied between the transparent anode 1011b and the transparent cathode 1011e of each first OLED subpixel 1011, the transparent display region 101 performs a light transmitting function.
The first OLED subpixels 1011 may be in an array form, and in order to reduce the diffraction phenomenon of the transparent display region 101 under the light transmission function, it is preferable to simplify the distribution of the first OLED subpixels 1011, for example, in rows and columns or in columns and rows. When the first OLED sub-pixels 1011 are arranged in a plurality of rows and columns, the transparent anodes 1011b of the first OLED sub-pixels 1011 are arranged in a plurality of columns and rows, and the transparent cathodes 1011e of all the first OLED sub-pixels 1011 are one-side electrodes. When the first OLED sub-pixels 1011 are arranged in a row and a plurality of rows, the transparent anodes 1011b of the first OLED sub-pixels 1011 are arranged in a row and a plurality of rows, and the transparent cathodes 1011e of all the first OLED sub-pixels 1011 are one surface electrode.
FIG. 5 is a schematic cross-sectional structure diagram of a second OLED sub-pixel in a non-transparent display area. Referring to fig. 1 to 4, the non-transparent display region 102 includes a plurality of second OLED subpixels 1021 arranged in an array, and each of the second OLED subpixels 1021 at least sequentially includes from bottom to top: a reflective anode 1021b formed on a light transmissive substrate 1021a, a pixel defining layer 1021c having an opening, an OLED light emitting material layer 1021d located within the opening, and a light transmissive cathode 1021e located on the OLED light emitting material layer 1021 d.
When a driving voltage is applied between the reflective anode 1021b and the transmissive cathode 1021e of each second OLED subpixel 1021, the non-transparent display region 102 performs a display function.
When the second OLED subpixel 1021 is AM driven, the reflective anode 1021b of the second OLED subpixel 1021 is a block anode, and the transmissive cathodes 1021e of all the second OLED subpixels 1021 can be one surface electrode.
Referring to fig. 2, the transition display area 103 may include a transparent display area extension area 101a and a non-transparent display area extension area 102 a. The transparent display area extension area 101a is connected with the transparent display area 101 and comprises a plurality of first OLED sub-pixels 1011; the non-transparent display region extension region 102a is connected to the non-transparent display region 102 and includes a plurality of second OLED subpixels 1021. It can be seen that the alignment deviation range of the polarizer opening 11a corresponds to the boundary deviation range of the transparent display region 101 and the non-transparent display region 102. In other words, in the transitional display area 103, the polarizer 11 may be completely covered, or the polarizer 11 may be partially covered and partially uncovered; the transparent display region extension region 101a and the non-transparent display region extension region 102a may be included, or only the transparent display region extension region 101a or only the non-transparent display region extension region 102a may be included.
Referring to fig. 3(a) and 3(b), when the entire screen formed by the transparent display area 101, the non-transparent display area 102, and the transition display area 103 displays a still image, the transition display area 103 is dark. The dark area means that the brightness difference of each pixel in the area cannot be recognized by human eyes. The scheme can improve the user experience when the full-face screen is used.
The static image may be identified by a format, such as jpg, jpeg, gif, png, bmp format.
In an alternative, the transition display area 103 may be dark by a structural arrangement, for example, black glue is disposed in the transition display area 103, and no pixels or sparse pixels are disposed in the transition display area 103. In another alternative, the transition display area 103 is implemented as a dark area by a display control method.
Fig. 6 is a flowchart of a display control method.
Referring to fig. 6, step S11 is first executed to obtain an original still image;
step S12 is executed to keep the original gray-level values of the pixels in the original static image corresponding to the transparent display area and the non-transparent display area unchanged, and reduce the original gray-level values of the pixels in the original static image corresponding to the transitional display area to obtain a static image to be displayed for the transparent display area, the non-transparent display area, and the transitional display area to display.
It can be seen that in the flow shown in fig. 6, the dark area of the transitional display area 103 is realized by reducing the original gray-scale value of each pixel in the transitional display area in the original still image.
Specifically, according to the scheme, the original gray values of the first OLED sub-pixels 1011 and/or the second OLED sub-pixels 1021 in the transitional display area in the original static image are processed, and the original gray values of the first OLED sub-pixels 1011 in the transparent display area and the second OLED sub-pixels 1021 in the non-transparent display area in the original static image are not changed, so that a static image to be displayed is obtained.
In the luminance-specific adjustment process, in one alternative, the degree of brightness of the dark area does not fluctuate with the initial degree of brightness in the still image. The scheme can be realized by setting the display gray value of each first OLED subpixel 1011 and/or second OLED subpixel 1021 in the transitional display area to 0.
In another alternative, the degree of darkness of dark areas fluctuates with the initial degree of darkness in the static image. Specifically, in the transitional display area 103, the ratio of the display gray value to the original gray value of each of the first OLED subpixel 1011 and/or the second OLED subpixel 1021 in the transitional display area may be a) fixed or b) not fixed. It can be understood that, compared with the different reduction ratios of the gray value in the scheme b), the scheme a) adopts the same ratio to reduce the gray value, and the implementation method is simple and has lower cost. The above ratio may be 50% or less, 25% or less, or 10% or less. The original gray value can be reduced to less than half, less than one fourth, less than one tenth, etc. according to the specific product of the OLED substrate, and the brightness difference between the first OLED subpixel 1011 and/or the second OLED subpixel 1021 in the transitional display area 103 can not be recognized by human eyes.
After the static image to be displayed is obtained, the driving voltage of each first OLED subpixel 1011 and/or each second OLED subpixel 1021 in the transitional display area is determined according to the gamma curve of the transparent display area 101 or the non-transparent display area 102.
Corresponding to the display control method, an embodiment of the invention further provides a display control apparatus 12. Fig. 7 is a block diagram of the display control apparatus.
Referring to fig. 7, the display control device 12 includes: an image acquisition module 12a, an image processing module 12b and a display driving module 12 c; wherein the content of the first and second substances,
the image obtaining module 12a is used for obtaining an original static image;
the image processing module 12b is configured to keep original gray values of pixels in the original static image corresponding to the transparent display area 101 and the non-transparent display area 102 unchanged, and reduce the original gray values of pixels in the original static image corresponding to the transition display area 103 to obtain a static image to be displayed;
the display driving module 12c is configured to display a still image to be displayed in the transparent display area 101, the non-transparent display area 102, and the transition display area 103.
The image acquisition module 12a and the image processing module 12b, and/or the image processing module 12b and the display driving module 12c may be connected by a wire, or may be wirelessly communicated to achieve data acquisition.
The image obtaining module 12a, the image processing module 12b and the display driving module 12c may be integrated on a chip, or the display driving module 12c may be a Display Driving Integrated Chip (DDIC), and the image obtaining module 12a and the image processing module 12b are integrated on a Central Processing Unit (CPU) of the display terminal.
Specifically, for the image processing module 12b, when the original gray-scale value of each pixel corresponding to the transitional display area 103 in the original still image is reduced, the ratio a) or b) of the display gray-scale value to the original gray-scale value of each of the first OLED subpixel 1011 and/or the second OLED subpixel 1021 in the transitional display area 103 is fixed. It can be understood that, compared with the different reduction ratios of the gray value in the scheme b), the scheme a) adopts the same ratio to reduce the gray value, and the implementation method is simple and has lower cost. The above ratio may be 50% or less, 25% or less, or 10% or less. The original gray value can be reduced to less than half, less than one fourth, less than one tenth, etc. according to the specific product of the OLED substrate, and the brightness difference between the first OLED subpixel 1011 and/or the second OLED subpixel 1021 in the transitional display area 103 can not be recognized by human eyes.
For the image processing module 12b, when the original gray-scale value of each pixel in the original still image corresponding to the transitional display area 103 is reduced, the gray-scale value displayed by each of the first OLED subpixel 1011 and/or the second OLED subpixel 1021 in the transitional display area may be set to 0.
In the display driving module 12c, gamma curves of the transparent display area 101 or the non-transparent display area 102 are pre-stored. The gamma curve is a relationship curve between the driving voltage and the gray scale value of each pixel. The gray values are known, and the data voltages of the first OLED subpixel 1011 and the second OLED subpixel 1021 in the transparent display area 101, the non-transparent display area 102 and the transition display area 103 can be determined.
Fig. 8 is a flowchart of another display control method.
Referring to fig. 8, step S21 is first executed to obtain an original driving voltage corresponding to an original gray-level value of each pixel in an original static image;
step S22 is executed to keep the original driving voltage of each pixel in the original static image corresponding to the transparent display area and the non-transparent display area unchanged, and reduce the original driving voltage of each pixel in the original static image corresponding to the transitional display area, so as to obtain a set of driving voltages to be applied to each pixel in the transparent display area, the non-transparent display area, and the transitional display area simultaneously.
It can be seen that, in the scheme, after the original gray value data of the original static image is sent to the display driving module, the data voltage provided to each pixel by the data signal channel is changed.
In an alternative, the light-to-dark level of the dark area does not fluctuate with the initial light-to-dark level in the still image during the specific adjustment of the driving voltage. According to the scheme, the driving transistors of the first OLED sub-pixel 1011 and/or the second OLED sub-pixel 1021 in the transitional display area can be turned off by adjusting the reduced driving voltage of the first OLED sub-pixel 1011 and/or the second OLED sub-pixel 1021 in the transitional display area. For an N-type drive transistor, the target drive voltage is low; for a P-type drive transistor, the target drive voltage is high.
In another alternative, the level of darkness of the dark regions fluctuates with the initial level of darkness in the static image. Specifically, a relationship curve between the driving voltage to be applied and the original driving voltage may be pre-stored, and the relationship curve is suitable for each first OLED subpixel 1011 and/or second OLED subpixel 1021 in the transitional display area 103; and determining the driving voltage to be applied to each first OLED sub-pixel 1011 and/or each second OLED sub-pixel 1021 in the transitional display area in the original static image based on the relation curve. It can be understood that each pixel adopts the same rule to obtain the driving voltage to be applied, and compared with a scheme that each pixel adopts different rules to obtain the voltage to be applied, the method is simple to implement and has lower cost.
In an alternative, in the relationship curve, the ratio of the display gray value corresponding to the to-be-applied driving voltage to the original gray value corresponding to the original driving voltage is fixed. The scheme associates the gray-scale value with the driving voltage, and can realize the dark area with the same brightness degree no matter the gray-scale value or the driving voltage is adjusted.
The above ratio may be 50% or less, 25% or less, or 10% or less. The original gray value can be reduced to less than half, less than one fourth, less than one tenth, etc. according to the specific product of the OLED substrate, and the brightness difference between the first OLED subpixel 1011 and/or the second OLED subpixel 1021 in the transitional display area 103 can not be recognized by human eyes.
Corresponding to the display control method, another embodiment of the invention further provides a display control apparatus 12'. Fig. 9 is a block diagram of the display control apparatus.
Referring to fig. 9, the display control device 12' includes: a display driving module 12c and a driving voltage processing module 12 d; wherein the content of the first and second substances,
the display driving module 12c is configured to obtain an original driving voltage corresponding to an original gray value of each pixel in the original static image;
the driving voltage processing module 12d is configured to keep the original driving voltages of the pixels in the original static image corresponding to the transparent display area 101 and the non-transparent display area 102 unchanged, reduce the original driving voltages of the pixels in the original static image corresponding to the transitional display area 103, and obtain a set of driving voltages to be applied to the pixels in the transparent display area 101, the non-transparent display area 102, and the transitional display area 103 simultaneously.
The display driving module 12c and the driving voltage processing module 12d may be connected by a wire, or may be wirelessly communicated to obtain data.
The driving voltage processing module 12d and the display driving module 12c may be integrated on a chip, or the display driving module 12c may be a Display Driving Integrated Chip (DDIC), and the driving voltage processing module 12d is integrated on a Central Processing Unit (CPU) of the display terminal.
Specifically, for the driving voltage processing module 12d, when the original driving voltage of each pixel corresponding to the transitional display area 103 in the original still image is reduced, the driving voltage to be applied to each pixel of the transitional display area may turn off the driving transistor of each pixel.
Specifically, for the driving voltage processing module 12d, the driving voltage to be applied of each pixel in the transitional display area may also be determined based on the stored relationship curve between the driving voltage to be applied and the original driving voltage; this relationship applies to each of the first OLED subpixel 1011 and/or the second OLED subpixel 1021 of the transitional display area 103.
Specifically, in the stored relationship curve between the to-be-applied driving voltage and the original driving voltage, the ratio of the display gray value corresponding to the to-be-applied driving voltage to the original gray value corresponding to the original driving voltage is fixed.
The stored relationship between the applied driving voltage and the original driving voltage may be less than 50%, 25% or 10%. The original gray value can be reduced to less than half, less than one fourth, less than one tenth, etc. according to the specific product of the OLED substrate, and the brightness difference between the first OLED subpixel 1011 and/or the second OLED subpixel 1021 in the transitional display area 103 can not be recognized by human eyes.
In fig. 3(a), the transparent display area 101 is shaped like a drop, but may be shaped like a rectangle, a circle, an ellipse, or a bang, among other alternatives. In fig. 3(a), the transitional display area 103 forms a non-closed ring around the transparent display area 101, and when the transitional display area 103 is adjusted to form a dark area, the dark area is a non-closed dark ring. In fig. 3(b), the transitional display area 103 forms a closed ring around the transparent display area 101, and when the transitional display area 103 is adjusted to form a dark area, the dark area is a closed dark ring.
In an alternative, when the full-screen composed of the transparent display area 101, the non-transparent display area 102 and the transitional display area 103 displays a dynamic image together, the display gray scale values of the first OLED subpixel 1011 and the second OLED subpixel 1021 in the transparent display area 101, the non-transparent display area 102 and the transitional display area 103 correspond to the original gray scale values of the pixels in the dynamic image. In other words, the original gray level of each of the first OLED subpixel 1011 and/or the second OLED subpixel 1021 in the transitional display area 103 corresponding to the polarizer alignment deviation range is not adjusted. This is because: for an average user, each detail in the image is generally observed only in a static image, while a dynamic image is less focused on each detail in the image because of faster refreshing. The scheme can reduce the requirement on the data processing capacity of the drive chip, and simultaneously does not influence the user experience.
In another alternative, when the full-screen composed of the transparent display area 101, the non-transparent display area 102 and the transitional display area 103 displays a dynamic image together, the display gray scale value of each first OLED subpixel 1011 and/or each second OLED subpixel 1021 in the transitional display area 103 may be reduced according to the display control method and apparatus for a static image.
The dynamic image may be a video, identified by a video format, such as AVI, WMV, RM, RMVB, MPEG1, MPEG2, MPEG4(MP4), 3GP, ASF, SWF, VOB, DAT, MOV, M4V, FLV, F4V, MKV, MTS, TS, and so forth.
