Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The inventor has found that the existing display module includes a plurality of display pixel groups, and the display sub-pixels in each display pixel group together form a visual display screen. However, since the pixel arrangement of the display sub-pixels in the display pixel group is not necessarily a regular rectangular array, there may be a case where a part of the display sub-pixels protrudes from the boundary of the arrangement pattern of the display pixel group, which may cause the edge color of the display screen to be visually biased toward the color of the display sub-pixels protruding from the boundary of the arrangement pattern, rather than the color of the preset screen, thereby reducing the visual experience of the user. Accordingly, the present invention provides a new display module.
Fig. 1 is a schematic diagram illustrating a pixel arrangement of a display module according to an embodiment of the present disclosure. As shown in fig. 1, the display module includes: a plurality of display pixel groups 1, compensation pixel groups 2, and a compensation control module (electrically connected to each compensation sub-pixel 21, not shown in fig. 1).
As shown in fig. 1, each display pixel group 1 includes a plurality of display sub-pixels, the plurality of display pixel groups 1 are arranged in a pattern as shown in fig. 1, and a boundary within a dashed-line frame in fig. 1 is a boundary of the arrangement pattern of the plurality of display pixel groups 1. At least one display pixel group 1 includes a display sub-pixel 11 that protrudes the boundary of the arrangement pattern formed by the plurality of display pixel groups 1 and a display sub-pixel 12 that does not protrude the boundary of the arrangement pattern formed by the plurality of display pixel groups 1. Each compensation pixel group 2 comprises at least one compensation sub-pixel 21, the compensation pixel group 2 being arranged adjacent to the display sub-pixel 11 at the boundary of the protruding arrangement pattern, for example adjacent to the left or right side of the display sub-pixel 11 as shown in fig. 1.
It is understood that a plurality means more than two in the present application.
The compensation control module is configured to control the compensation sub-pixel 21 to emit the compensation light to compensate for the display light emitted by the display sub-pixel 11 protruding the boundary of the arrangement pattern. Specifically, the compensation control module may drive the compensation sub-pixel 21 to emit the compensation light by controlling the driving module, which may be a thin film transistor. The compensation control module may be an independent control chip, or may be a partial module of the control chip, as long as it is a module having a control display function, and the structure of the compensation control module is not specifically limited in the present application.
The display pixel group 1 is controlled by the display control module to emit display light. The display control module applies a control voltage to the display pixel group 1, and controls the display pixel group 1 to emit display light through the control voltage, so that a preset picture is displayed. The compensation sub-pixel 21 is controlled by the compensation control module to emit compensation light. In an embodiment, the compensation control module calculates a compensation voltage of the compensation sub-pixel 21 according to a preset picture to be displayed, and controls the compensation sub-pixel 21 to emit compensation light through the compensation voltage, so as to compensate the display light emitted by the display sub-pixel 11 protruding out of the boundary of the arrangement pattern, so that the display module can normally display the preset picture.
It should be understood that the display control module for controlling the display pixel group 1 to emit the display light and the compensation control module for controlling the compensation sub-pixel 21 to emit the compensation light may be implemented by separate control chips, or may be implemented by integrating as one chip, and the specific implementation forms of the display control module and the compensation control module are not strictly limited in this application.
Therefore, by setting the compensation sub-pixel 21 and enabling the compensation control module to control the compensation sub-pixel 21 to emit the compensation light to compensate the display light emitted by the display sub-pixel 11 protruding out of the boundary of the arrangement pattern, the display light emitted by the display sub-pixel 11 protruding out of the boundary of the arrangement pattern is compensated by the compensation light emitted by the compensation sub-pixel 21, so that the edge of the display picture is not biased to the color of the display sub-pixel 11 protruding out of the boundary of the arrangement pattern in the visual sense, but is preset with the color of the picture, thereby significantly improving the visual experience of the user.
It should be understood that the arrangement of the display pixel group 1 and the arrangement of the display sub-pixels in the display pixel group 1 are not limited to the arrangement shown in fig. 1, but may be selected or adjusted according to the actual application. As long as one display pixel group 1 includes the display sub-pixels 11 protruding the boundary of the arrangement pattern formed by the plurality of display pixel groups 1, the compensation sub-pixels 21 provided in the embodiments of the present application can be used to realize display compensation, and the present application does not specifically limit the arrangement manner of the plurality of display pixel groups 1 and the arrangement manner of the display sub-pixels in the display pixel groups 1.
It should also be understood that the compensation sub-pixel 21 may be adjacently disposed at the left, right, above or below the display sub-pixel 11 at the boundary of the protruding arrangement pattern, as long as the compensation sub-pixel is adjacently disposed without overlapping with other display sub-pixels, and the present application does not specifically limit the adjacent arrangement manner of the compensation sub-pixel 21 with respect to the display sub-pixel 11 at the boundary of the protruding arrangement pattern. For example, as shown in fig. 2, in one embodiment, the compensation sub-pixel 21 may be disposed adjacent to and above or below the display sub-pixel 11 at the boundary of the protrusion arrangement pattern. For example, as shown in fig. 3, in an embodiment, the display sub-pixel 11 protrudes upward from the boundary of the arrangement pattern, and the compensation sub-pixel 21 may be disposed adjacent to the display sub-pixel 11 disposed above and to the left or right of the boundary of the arrangement pattern. For the boundary of the display sub-pixel 11 protruding downward from the arrangement pattern, the compensation sub-pixel 21 may be disposed adjacent to the lower side and the left or right side of the display sub-pixel 11 disposed at the boundary of the protruding arrangement pattern.
Fig. 4 is a schematic diagram illustrating a pixel arrangement of a display module according to another embodiment of the present disclosure. As shown in fig. 4, the display module includes a compensation pixel group 2, and the compensation pixel group 2 includes a plurality of compensation sub-pixels 21. The compensation pixel group 2 can emit compensation light with richer colors relative to the single compensation sub-pixel 21, and the compensation pixel group 2 can emit the compensation light to compensate the display light emitted by the display sub-pixel 11 protruding out of the boundary of the arrangement pattern, so that the display light emitted by the display sub-pixel 11 protruding out of the boundary of the arrangement pattern can be compensated more sufficiently, and the edge of the preset picture is closer to the color of the preset picture.
In an embodiment, the plurality of display pixel sets 1 are arranged in an array, the display module may include a plurality of compensation pixel sets 2 arranged in an array, and the plurality of compensation pixel sets 2 arranged in an array are disposed adjacent to the display sub-pixels 11 protruding the boundary of the arrangement pattern.
Specifically, since the plurality of display pixel groups 1 are arranged in an array, the display sub-pixels 11 protruding the boundary of the arrangement pattern may be a row or a column of display sub-pixels 11 of the same color regularly arranged to protrude the boundary of the arrangement pattern, that is, the display sub-pixels 11 of the same color protrude from one side of the arrangement pattern, so that one side of the display screen may emit light of the same color, and particularly, when the preset screen is a white screen, one side of the screen visually displayed may emit light of the same color. For example, the display sub-pixel 11 at the boundary of the convex array pattern is a red sub-pixel, and one side of the screen visually displayed emits red light. The compensation pixel groups 2 arranged in an array are arranged adjacent to the display sub-pixels 11 protruding from the boundaries of the arrangement pattern, so that the light of a single color at the edges of the display screen can be compensated, for example, the display sub-pixels 11 protruding from the boundaries of the arrangement pattern are red sub-pixels, the compensation pixel groups 2 arranged in an array are arranged adjacent to one side of the red sub-pixels, and the compensation pixel groups 2 arranged in an array can emit blue light and green light with various brightness to compensate the red light emitted by the red sub-pixels, so that the light of a single color at the whole edges of the display screen is compensated, and all the edges of the display screen can visually emit light of a preset screen color.
In an embodiment, the plurality of display pixel groups 1 and all the compensation sub-pixels 21 are configured to completely display the predetermined picture with the predetermined resolution, that is, the compensation sub-pixels 21 and the display sub-pixels in the display pixel groups 1 are configured to participate in the display of the predetermined picture, but the display light at the edge of the display picture is actually formed after the compensation control module controls the compensation sub-pixels 21 to emit the compensation light to compensate the display light emitted by the display sub-pixels 11 at the edge of the protrusion arrangement pattern. For example, the display module includes a compensation pixel group 2, the compensation pixel group 2 includes a plurality of compensation sub-pixels 21, the compensation pixel group 2 and the display sub-pixels in the display pixel group 1 are configured together to participate in the display of the preset picture at a resolution 168 × 426, that is, a pixel group with 168 rows and 426 columns arranged in an array is configured to participate in the display of the preset picture, but the display light at the edge of the display picture is actually the compensation light emitted by the compensation pixel group 2, that is, the pixel groups in the first row and the last row are actually used to emit the compensation light, and actually the display picture is displayed at the resolution 166 × 426 to display the preset picture, so that the edge of the display picture is not visually biased toward the color of the display sub-pixels at the boundary of the convex arrangement pattern, thereby significantly improving the visual experience of the user.
In an embodiment, the plurality of display pixel sets 1 may be configured to completely display the preset picture with the preset resolution, that is, completely display the preset picture with the preset number of display pixel sets 1, and the compensation sub-pixels 21 are additionally arranged to compensate the display light at the edge of the display picture, and the compensation sub-pixels 21 themselves do not participate in the display of the preset picture. For example, the display module includes a compensation pixel group 2, the compensation pixel group 2 includes a plurality of compensation sub-pixels 21, the display sub-pixels in the display pixel group 1 are configured to participate in the display of the preset picture at a resolution of 168 × 426, that is, the display pixel group 1 having 168 rows and 426 columns arranged in an array is configured to participate in the display of the preset picture, and the other two compensation pixel groups 2 are configured to compensate the display light at the upper and lower edges of the display picture, that is, the display picture is configured to participate in the light emission at the resolution of 170 × 426, wherein the display picture emits the display light at the resolution of 168 × 426 of the display pixel group 1, thereby displaying the preset picture, and emits the compensation light at the resolution of 2 × 426 of the compensation pixel group 2, thereby compensating the display light emitted by the display pixel group 1. By compensating the display light emitted by the compensation sub-pixel 21 to the display light emitted by the display sub-pixel 11 protruding the arrangement pattern boundary, the preset picture can be completely displayed by the arranged display pixel group 1, and the situation that the preset picture edge cannot be displayed visually due to the lack of pixel display at the preset picture edge can not occur.
Fig. 5 is a schematic diagram illustrating a pixel arrangement of a display module according to another embodiment of the present disclosure. As shown in the pixel arrangement of fig. 5, the display pixel group 1 includes a display sub-pixel 111 emitting light of a first color, a display sub-pixel 112 emitting light of a second color, and a display sub-pixel 113 emitting light of a third color. The display sub-pixels 111 emitting the first color light and the display sub-pixels 112 emitting the second color light are arranged in a first row, the display sub-pixels 113 emitting the third color light are arranged in parallel with the first row, the display sub-pixels 111 emitting the first color light are upwardly protruded, and the display sub-pixels 112 emitting the second color light are downwardly protruded. The display module assembly still includes: at least one row of compensation pixel groups 2 located above the plurality of display pixel groups 1 arranged in an array, and at least one row of compensation pixel groups 2 located below the plurality of display pixel groups 1 arranged in an array.
Specifically, referring to the pixel arrangement of fig. 5, the display sub-pixel 111 emitting the first color light protrudes upward, so that the displayed image is visually displayed with the first color instead of the color of the preset image, and the display sub-pixel 111 emitting the first color light is compensated by enabling the at least one row of compensation pixel group 2 to emit the compensation light, so that the displayed image is visually displayed with the color of the preset image instead of only the first color. Similarly, the display sub-pixel 112 emitting the second color light protrudes downward, so that the lower portion of the displayed picture is visually displayed as the second color instead of the color of the preset picture, and the display sub-pixel 112 emitting the second color light is compensated by making the at least one row of compensation pixel group 2 emit the compensation light, so that the lower portion of the displayed picture is visually displayed as the color of the preset picture instead of only the second color.
It should be understood that at least one row of compensation pixel group 2 may be a plurality of rows of compensation pixel groups 2, and may also be a row of compensation pixel groups 2, the number of rows of compensation pixel groups 2 may be selected according to a specific application scenario, and the number of rows of compensation pixel groups 2 is not specifically limited in this application.
In an embodiment, the first color light may be red light, the second color light may be green light, and the third color light may be blue light, and when the display light emitted by the display pixel group 1 is not compensated, the displayed picture may have a problem of being visually red-green, and particularly, in the case of a white picture, the displayed picture may have a problem of being visually red-green. After the display light emitted by the display pixel group 1 is compensated, the displayed picture does not have the phenomenon of red, green and blue in vision, but is displayed as the color of the preset picture.
In one embodiment, the compensation sub-pixels 21 of the compensation pixel set 2 correspond to the display sub-pixels of the display pixel set 1 in one-to-one correspondence and are arranged in the same manner. For example, the compensation pixel group 2 includes a compensation subpixel 211 emitting a first color light, a compensation subpixel 212 emitting a second color light, and a compensation subpixel 213 emitting a third color light. The compensation sub-pixels 211 emitting the first color light and the compensation sub-pixels 212 emitting the second color light are arranged in a first row, the compensation sub-pixels 213 emitting the third color light are arranged in parallel with the first row, the compensation sub-pixels 211 emitting the first color light are protruded upward, and the compensation sub-pixels 212 emitting the second color light are protruded downward. Because the plurality of compensation sub-pixels 21 of the compensation pixel group 2 correspond to the plurality of display sub-pixels of the display pixel group 1 in one-to-one correspondence and have the same arrangement mode, the compensation pixel group 2 and the display pixel group 1 can be prepared together without using an additional mask layer for an additional preparation process aiming at the compensation pixel group 2, and the preparation process of the display module can be simplified.
When at least one row of compensation pixel group 2 is located above the plurality of display pixel groups 1 arranged in an array, the compensation light emitted by the compensation sub-pixel 212 and the compensation sub-pixel 213 is mainly used for compensating the display light emitted by the display sub-pixel 111, because only a part of the display sub-pixel 111 protrudes the boundary of the arrangement pattern, the compensation sub-pixel 212 and the compensation sub-pixel 213 emit compensation light with a lower brightness than the display light emitted by the display sub-pixel 111, while the compensation subpixel 211 is spaced from the display subpixel 111 by the compensation subpixel 212, the compensation sub-pixel 211 emits compensation light having a lower brightness than the compensation sub-pixels 212 and 213, and therefore, even if the compensation sub-pixel 211 protrudes upward in the compensation pixel group 2, the color of the compensation light emitted by the compensation sub-pixel 211 is not visually seen due to the low luminance of the compensation sub-pixel 211. Similarly, when at least one row of compensation pixel group 2 is located below the plurality of display pixel groups 1 arranged in the array, the color of the compensation light emitted by the compensation sub-pixel 212 is not visually seen.
Fig. 6 is a schematic diagram illustrating a pixel arrangement of a display module according to another embodiment of the present disclosure. As shown in fig. 6, different from the embodiment shown in fig. 5, when at least one row of compensation pixel groups 2 is located above the plurality of display pixel groups 1 arranged in an array, the compensation sub-pixel 211 emitting the first color light is not protruded upwards in the compensation pixel group 2, but is flush with the compensation sub-pixel 213 emitting the third color light. Similarly, when at least one row of compensation pixel group 2 is located below the plurality of display pixel groups 1 arranged in an array, the edge of the display image does not generate a single color that does not belong to the edge of the preset image.
Based on the display module assembly of the above embodiment, an embodiment of the application further provides a display compensation method of the display module assembly. The display compensation method comprises the following steps: controlling the compensation pixel group 2 to emit compensation light to compensate the display light emitted by the display sub-pixel 11 at the boundary of the convex arrangement pattern, i.e. controlling the compensation sub-pixel 21 to emit compensation light to compensate the display light emitted by the display sub-pixel 11 at the boundary of the convex arrangement pattern
The compensation sub-pixel 21 is controlled to emit compensation light to compensate for the display light emitted from the display sub-pixel 11 protruding the boundary of the arrangement pattern. The compensation light emitted by the compensation sub-pixel 21 is controlled to compensate the display light emitted by the display sub-pixel 11 which protrudes from the boundary of the arrangement pattern, so that the display light emitted by the display sub-pixel 11 which protrudes from the boundary of the arrangement pattern is compensated by the compensation light emitted by the compensation sub-pixel 21, and the edge of the display picture is visually the color of the preset picture.
Specifically, the control of the compensation sub-pixel 21 to emit the compensation light may be to compensate the display light emitted by the display sub-pixel 11 protruding from the boundary of the arrangement pattern by emitting a light of a fixed color, for example, the display light emitted by the display sub-pixel 11 protruding from the boundary of the arrangement pattern is red light, and the compensation sub-pixel 21 may be set to emit the compensation light as green light with a weaker brightness, so as to compensate the red light emitted by the display sub-pixel 11.
