Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
As shown in fig. 1 to 3, a display device 1 according to an embodiment of a first aspect of the present invention includes: a display area 11, a plurality of light emitting elements 12, and a control circuit.
The light emitted from the plurality of light emitting elements 12 can pass through the display region 11, that is, each of the plurality of light emitting elements 12 can emit light through the display region 11. Alternatively, the light emitting element 12 may be a self-light emitting element 12, or may be a backlight element.
The control circuit is used for controlling at least part of light emitted by the light emitting elements 12 in the plurality of light emitting elements 12 to emit light from the display area 11 in a first direction at a first moment so as to display a first image in the display area 11 in a direction opposite to the first direction, and the refresh frequency of the first image is not less than 24 frames per second.
For example, as shown in fig. 1, the left side of the display device 1 is a first image F1, the first image F1 is emitted from at least a part of the light emitting elements 12 through the display region 11 in a first direction a (e.g., the left direction of the display device 1), and the first image F1 can be viewed in a direction a' opposite to the first direction a. Optionally, the at least part of the light emitting elements 12 may be directional light sources, thereby reducing light scattering to the space outside the field of view. Here, it should be understood that the "at least part of the light emitting elements 12" may refer to a part of all the light emitting elements 12 in the display device 1, or may refer to all the light emitting elements 12 in the display device 1. Further, the light emitted from the at least part of the light emitting elements 12 is emitted from the display area 11 in the first direction a, so that the first image F1 displayed thereon occupies the entire display area 11, that is, the first image F1 is displayed in full screen. Moreover, the refresh frequency of the first image F1 is not less than 24 frames per second, so that the display device 1 can achieve the effect of displaying the first image F1 at all times in the opposite direction a' to the first direction a due to the persistence of vision of human eyes.
The control circuit is further configured to control at least some of the light emitting elements 12 of the plurality of light emitting elements 12 to emit light from the display area 11 in a second direction at a second time, so as to display a second image in the display area 11 in a direction opposite to the second direction, wherein the refresh frequency of the second image is not less than 24 frames per second, and the second image sequentially reciprocates.
For example, as shown in fig. 1, the right side of the display device 1 is a second image F2, the second image F2 is emitted by at least part of the light emitting elements 12 through the display region 11 in a second direction B (e.g., the right side direction of the display device 1), and the second image F2 can be viewed in a direction B' opposite to the second direction B. Optionally, the at least part of the light emitting elements 12 may be directional light sources, thereby reducing light scattering to the space outside the field of view. Here, it should be understood that "at least part of the light emitting elements 12" herein may refer to a part of all the light emitting elements 12 in the display device 1, or may refer to all the light emitting elements 12 in the display device 1. Further, the light emitted from the at least part of the light emitting elements 12 is emitted from the display area 11 in the second direction B, so that the second image F2 displayed thereon can occupy the whole display area 11, that is, the second image F2 is displayed in full screen. Moreover, the refresh frequency of the second image F2 is not less than 24 frames per second, so that the display device 1 can achieve the effect of displaying the second image F2 at all times in the reverse direction B' of the second direction B due to the persistence of vision of human eyes.
The control circuit controls at least part of the light emitting elements 12 of the plurality of light emitting elements 12 to emit light from the display area 11 in a first direction a at a first moment, and the control circuit is further configured to control at least part of the light emitting elements 12 of the plurality of light emitting elements 12 to emit light from the display area 11 in a second direction B at a second moment, and the light is sequentially emitted and repeated to form a complete image display effect. That is, for example, at a first time, the control circuit controls at least some of the light emitting elements 12 to emit light from the display area 11 in the first direction a, at a second time, the control circuit controls at least some of the light emitting elements 12 to emit light from the display area 11 in the second direction B, at a third time, the control circuit controls at least some of the light emitting elements 12 to emit light from the display area 11 in the first direction a, and at a fourth time, the control circuit controls at least some of the light emitting elements 12 to emit light from the display area 11 in the second direction B, and the light emitting elements 12 are controlled to emit light in at least two different directions sequentially. Therefore, the display device 1 can display the same or different image pictures in the same time and different directions, and each image picture can be displayed in a full screen.
In summary, according to the display device 1 of the embodiment of the invention, through the control of the control circuit, at least some of the light emitting elements 12 of the plurality of light emitting elements 12 are controlled to emit light from the display area 11 in the first direction at the first time, and the refresh frequency of the first image is not less than 24 frames per second, and at least some of the light emitting elements 12 of the plurality of light emitting elements 12 are controlled to emit light from the display area 11 in the second direction at the second time, and the refresh frequency of the second image is not less than 24 frames per second, so that the display device 1 according to the embodiment of the invention can display the same or different image frames in the same time and different directions, and each image frame can be displayed in a full screen.
In the example shown in fig. 1, the first image F1 and the second image F2 displayed by the display device 1 in the left and right two directions, respectively, are displayed, but the present invention is not limited thereto, and the display device 1 of the present invention may also display more images in more directions, for example, three, four, or more.
As shown in fig. 2, in the embodiment of the present invention, the plurality of light emitting elements 12 are arranged in an array of rows and columns, and optionally, the size of each light emitting element 12 may be nanometer, so that the light emitting elements 12 may be densely arranged in a limited display area, and thus, an image displayed by the display device 1 may be clearer and finer. For example, the light emitting element 12 in the present invention may be a micro led (micro light emitting diode).
Alternatively, each light emitting element 12 may include at least three sub-emitting pixels, each emitting a different color, respectively.
For example, in the present invention, each light emitting element 12 includes three sub-emitting pixels, and optionally, the three sub-emitting pixels may be an R sub-emitting pixel, a G sub-emitting pixel, and a B sub-emitting pixel, respectively, where the R sub-emitting pixel is a red sub-emitting pixel, the G sub-emitting pixel is a green sub-emitting pixel, and the B sub-emitting pixel is a blue sub-emitting pixel, and in each pixel, the color and brightness displayed by each pixel point are controlled by the size of the three color components of the three sub-emitting pixels. That is, in the present example, the display device 1 may adopt the RGB color standard.
Of course, the present invention is not limited to this, and in another example of the present invention, each light emitting element 12 includes four sub-emitting pixels (not shown), and optionally, the four sub-emitting pixels may be an R sub-emitting pixel, a G sub-emitting pixel, a B sub-emitting pixel, and a W sub-emitting pixel, respectively, wherein the R sub-emitting pixel is a red sub-emitting pixel, the G sub-emitting pixel is a green sub-emitting pixel, the B sub-emitting pixel is a blue sub-emitting pixel, and the W sub-emitting pixel is a white sub-emitting pixel, and in each pixel, the color and brightness displayed by each pixel point are controlled by the size of the four color components of the four sub-emitting pixels. That is, in the present example, the display device 1 may adopt the RGBW color standard.
Further, in a third example of the present invention, the four sub-emissive pixels in the above example may be a C sub-emissive pixel, an M sub-emissive pixel, a Y sub-emissive pixel, and a K sub-emissive pixel, respectively, wherein the C sub-emissive pixel is a cyan sub-emissive pixel, the M sub-emissive pixel is a magenta sub-emissive pixel, the Y sub-emissive pixel is a yellow sub-emissive pixel, and the K sub-emissive pixel is a black sub-emissive pixel, and in each pixel, the color and brightness displayed by each pixel point are controlled by the size of the four color components of the four sub-emissive pixels. That is, in the present example, the display device 1 may adopt the CMYK color standard.
In some embodiments of the present invention, at least some of the light emitting elements 12 that emit light from the display area 11 in the first direction a at a first instant are uniformly arranged below the display area 11, and at least some of the light emitting elements 12 that emit light from the display area 11 in the second direction B at a second instant are uniformly arranged below the display area 11. Thus, the first image F1 formed by the above-described light rays exiting in the first direction a can be displayed on the entire screen, that is, the first image F1 is a full-screen image; accordingly, the second image F2 formed by the above-described outgoing light rays in the second direction B can be displayed on the entire screen, that is, the second image F2 is a full-screen image. Thereby, the full screen display of the image can be conveniently realized.
As shown in fig. 2, in the specific example of the present invention, it is assumed that at least a portion of the light emitting elements 12 emitting light from the display region 11 in the first direction a at the first time is represented by a white-backed box, and each of the portion of the light emitting elements 12 may include the R1 sub-pixel 121, the G1 sub-pixel 122, and the B1 sub-pixel 123, for example, in the RGB color standard. Similarly, it is assumed that at least a part of the light emitting elements 12 emitting light from the display region 11 in the second direction B at the second moment is represented by a gray-backed box, and each of the part of the light emitting elements 12 may include the R2 sub-pixel 124, the G2 sub-pixel 125, and the B2 sub-pixel 126, taking the RGB color standard as an example. In the display device 1, two portions of the light emitting elements 12 may be disposed at intervals row by row. Of course, the present invention is not limited thereto, and the two light emitting elements 12 may be disposed at intervals of columns. Alternatively, the two portions of light emitting elements 12 are arranged spaced apart from each other in each row or each column.
In some embodiments of the present invention, the display device 1 further includes a substrate on which the plurality of light emitting elements 12 are provided, wherein at least part of the light emitting portions of the light emitting elements 12 are obliquely mounted toward the first direction a or the second direction B. That is, in order to allow at least a part of the light emitting elements 12 to emit light in the first direction a or the second direction B, when the light emitting elements 12 are mounted, the light emitting parts of the part of the light emitting elements 12 may be obliquely mounted toward the first direction a so that the part of the light emitting elements 12 may emit light toward the first direction a. Similarly, the light emitting portions of some of the light emitting elements 12 may be obliquely mounted toward the second direction B, so that the some of the light emitting elements 12 may emit light toward the second direction B.
Of course, the present invention is not limited to this, and in order to make at least part of the light emitting elements 12 emit light in the first direction a or the second direction B, a lens may be disposed above the light emitting elements 12, so that the light emitting direction of the light emitting elements 12 is changed by the lens, thereby achieving the purpose of directional light emission.
Specifically, the display device 1 further includes a plurality of lenses disposed above at least some of the light emitting elements 12, so that at least some of the light emitted by the light emitting elements 12 exits the display area 11 in the first direction a or the second direction B. For example, in the example shown in fig. 2, it is assumed that at least a part of the light emitting elements 12 which will emit light from the display region 11 in the first direction a at the first time is indicated by a box with a white bottom, and each of the light emitting elements 12 includes the R1 sub-pixel 121, the G1 sub-pixel 122, and the B1 sub-pixel 123, and for example, a lens is disposed above the light emitting element 12 composed of three sub-pixels of the R1 sub-pixel 121, the G1 sub-pixel 122, and the B1 sub-pixel 123, and the direction of the emitted light of the light emitting element 12 is changed by the lens, so that the light emitted by the part of the light emitting element 12 is emitted from the display region 11 in the first direction a. The direction of the emitted light of the light-emitting element 12 can thereby be conveniently controlled.
For example, in the example shown in fig. 2, it is assumed that at least a part of the light emitting elements 12 which will emit light from the display region 11 in the second direction B at the second time is indicated by a box with a gray bottom, and each of the light emitting elements 12 includes the R2 sub-pixel 124, the G2 sub-pixel 125, and the B2 sub-pixel 126, and for example, a lens is disposed above the light emitting element 12 composed of three sub-pixels of the R2 sub-pixel 124, the G2 sub-pixel 125, and the B2 sub-pixel 126, and the direction of the emitted light of the light emitting element 12 is changed by the lens, so that the light emitted by the part of the light emitting element 12 is emitted from the display region 11 in the second direction B. The direction of the emitted light of the light-emitting element 12 can thereby be conveniently controlled.
In a specific example of the present invention, the plurality of lenses are integrally formed. It will be appreciated that all of the lenses may be formed as a unitary component, or that some of all of the lenses may be integrally formed as a unitary component and another portion may be formed as a component of another unitary structure. And on the integrated lens structure, corresponding to the upper side of the light emitting element 12, a corresponding lens portion is arranged to correspondingly change the direction of the light emitted from the light emitting element 12. Therefore, the structure of the lens can be simplified, the installation steps can be simplified, and the cost can be reduced.
Of course, the present invention is not limited thereto, and in order to make at least part of the light emitting elements 12 emit light in the first direction a or the second direction B, a reflective plate may be disposed below the light emitting elements 12, so that the light emitting direction of the light emitting elements 12 is changed by the reflective plate, thereby achieving the purpose of directional light emission.
Specifically, the display device 1 further includes a plurality of reflective plates disposed below at least some of the light emitting elements 12, so that at least some of the light emitted from the light emitting elements 12 exits the display region 11 in the first direction a or the second direction B. For example, in the example shown in fig. 2, it is assumed that at least a part of the light emitting elements 12 which will emit light from the display region 11 in the first direction a at the first time is indicated by a box with a white bottom, and each of the light emitting elements 12 includes the R1 sub-pixel 121, the G1 sub-pixel 122, and the B1 sub-pixel 123, and for example, a reflecting plate is disposed below the light emitting element 12 composed of three sub-pixels of the R1 sub-pixel 121, the G1 sub-pixel 122, and the B1 sub-pixel 123, and the direction of the emitted light of the light emitting element 12 is changed by the reflecting plate, so that the light emitted by the part of the light emitting element 12 is emitted from the display region 11 in the first direction a. The direction of the emitted light of the light-emitting element 12 can thereby be conveniently controlled.
For example, in the example shown in fig. 2, it is assumed that at least a part of the light emitting elements 12 which will emit light from the display region 11 in the second direction B at the second time is indicated by a box with a gray bottom, and each of the light emitting elements 12 includes the R2 sub-pixel 124, the G2 sub-pixel 125, and the B2 sub-pixel 126, and for example, a reflecting plate is disposed below the light emitting element 12 composed of three sub-pixels of the R2 sub-pixel 124, the G2 sub-pixel 125, and the B2 sub-pixel 126, and the direction of the emitted light of the light emitting element 12 is changed by the reflecting plate, so that the light emitted by the part of the light emitting element 12 is emitted from the display region 11 in the second direction B. The direction of the emitted light of the light-emitting element 12 can thereby be conveniently controlled.
In a specific example of the present invention, the plurality of reflection plates are integrally formed. It will be appreciated that all of the reflective plates may be formed as a unitary component, or that some of all of the reflective plates may be integrally formed as a unitary component and some may be formed as a component of another unitary construction. And on the integrated reflector structure, a corresponding reflector portion is disposed below the light emitting element 12 to correspondingly change the direction of the light emitted from the light emitting element 12. Therefore, the structure of the reflecting plate can be simplified, the installation steps can be simplified, and the cost can be reduced.
In the embodiment of the present invention, the light emitting direction of the light emitting element 12 can be changed, so that the light emitting direction of the light emitting element 12 can be changed as required to expand the display effect of the display device 1.
In an alternative embodiment of the present invention, the display device 1 includes a plurality of first driving structures, and the plurality of first driving structures are respectively connected to at least some of the light emitting elements 12 to drive at least some of the light emitting elements 12 to rotate, and enable at least some of the light emitted by the light emitting elements 12 to exit from the display area 11 in the first direction a or the second direction B. Thus, the light emitting direction of each light emitting element 12 can be controlled individually.
