It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting. It will be apparent to one skilled in the art that the present invention may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the present invention.

Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
With the development of display technology, various display screens are more and more widely used. As a branch of the display technology field in the micro display field, a commonly used display screen has the characteristics of smaller area and lighter weight, and a display screen using single Crystal Silicon as a substrate in the micro display field, for example, micro-OLED, micro-LED, Liquid Crystal On Silicon (LCOS), and the like.
In particular, taking a micro-OLED as an example, in addition to having advantages of self-luminescence, thin thickness, light weight, large viewing angle, etc., the micro-OLED also has advantages of high pixel density, small volume, easy portability, low power consumption, etc., and thus is often applied to near-eye display devices, such as Virtual Reality (VR) devices, Augmented Reality (AR) devices, etc. In order to be able to provide a user with a rich picture and a good visual experience, in a display device, for example, display of image data may be performed in combination with the use of a lens having a circular, elliptical, and irregular shape.
In order to provide a clearer effect when the display device displays an image, for example, in a near-eye display device, a more real and immersive experience is provided, and more data needs to be transmitted to enhance the image quality of the image display, so that the data transmission rate is greatly increased, which is limited by design and process conditions, and an excessively high transmission rate affects the correctness and stability of data transmission, and conversely, affects the display effect of the image.
Further, when an image is displayed in a display device, it may be stored in a large number of invalid display areas, for example, a display substrate shown in fig. 1, specifically, the display may be substantially a single crystal silicon substrate, data to be displayed is scanned by a driving circuit, the data to be displayed is sent to a display substrate a1, and in order to be able to provide a rich visual experience for a user, lenses of different shapes, such as a circle, an ellipse, an irregular shape, and the like, may be incorporated in the display device. Therefore, a large amount of invalid display data exists in the image to be displayed corresponding to the lenses in different shapes, and a data channel is occupied in the image transmission process to transmit data, so that the data bandwidth is wasted.
Embodiments of the present invention provide a data transmission device and method, which can effectively reduce the amount of data to be transmitted, so as to improve the bandwidth utilization rate, thereby reducing the transmission rate, improving the accuracy and stability of data transmission, and stably displaying an image to be displayed.
Fig. 2 is a schematic structural diagram of a data transmission device according to an embodiment of the present invention. As shown in fig. 2, the data transmission apparatus includes a data processing module 110, a transmission path 120, a storage module 130, and a scanning module 140. The transmission path 120 may include a plurality of paths for transmitting data, that is, N transmission paths, where N is a positive integer. The data transmission device is connected to a data display device, which may include a display area for displaying images.
In some embodiments, the data transmission device and the data display device may be located on the same device. For example, the VR all-in-one machine may include data transmission equipment and data display equipment, process the image to be displayed through the data transmission equipment, send the effective image to be displayed in the image to be displayed to the data display equipment, and display the effective data to be transmitted in the display area of the display screen of the data display equipment.
The data transmission device and the data display device may also be located in different devices, for example, the data transmission device may be located in an electronic device such as a mobile phone or a computer, and the data display device is a separate device, for example, a mobile terminal display device. The data transmission device may send the valid data to be displayed to the data display device via a wireless transmission medium and/or a wired transmission medium.
In some embodiments, the data processing module 110 is configured to obtain an image to be displayed, and determine, according to a preset resolution, an effective image to be displayed of the image to be displayed in the display area, where the effective image to be displayed includes multiple lines of effective data to be transmitted.
The data processing module 110 is further configured to input, according to a preset data transmission rule, each row of valid data to be transmitted into the storage module through the N transmission paths.
And the scanning module 140 is configured to obtain each row of valid data to be transmitted from the storage module according to a preset scanning rule, and send the obtained data to the data display device.
In the data transmission device according to the embodiment of the present invention, the data processing module 110 may determine an effective image to be displayed in the image to be displayed according to the display area in the data display device, so as to reduce the amount of data to be transmitted. For example, in VR glasses, a square display substrate, that is, a display screen, is usually combined to display an image to be displayed through a circular or elliptical lens, so as to present a circular or elliptical display image, therefore, with the data transmission device provided in the embodiments of the present invention, when transmitting image data of an image to be displayed, only an effective image to be displayed in a display area is transmitted, and an ineffective band display image outside other display areas outside the display area is not transmitted, which not only can ensure a high-definition display effect, but also can reduce the amount of data to be transmitted as a whole, and improve the stability of data transmission.
Fig. 3 is a schematic diagram illustrating a display effect of a display screen according to an embodiment of the present invention. As shown in fig. 3, the display area may include, but is not limited to, a circle, and may be applied to an application scenario of image display such as VR, when the display screen displays an image, a gray portion is an ideal invalid display area, and a white portion is an effective display area, where a width of a grid is used to indicate a bit width size of analog data transmission.
Specifically, the data processing module 110 may acquire an image to be displayed.
In order to reduce the transmission of invalid data, the data processing module 110 may then determine an effective image to be displayed of the image to be displayed in the display area according to the preset resolution, where the effective image to be displayed includes multiple lines of effective data to be transmitted.
In some embodiments, when determining an effective image to be displayed in the display area of the image to be displayed, the data processing module 110 may specifically determine, according to a preset resolution, a data transmission bit width corresponding to the preset resolution.
In some embodiments, the preset resolution may be set according to actual display requirements of the display screen, and when the data transmission bit width is determined, the data transmission bit widths required by different display devices may be determined according to a preset matching relationship between the preset resolution and the data bit width.
Next, the data processing module 110 may determine, according to the data transmission bit width, a first effective image to be displayed of the image to be displayed in the display area, where the first effective image to be displayed includes a second effective image to be displayed and an edge transition display image. Illustratively, fig. 4 is a schematic diagram of an effective image to be displayed according to an embodiment of the present invention. The first effective display image may include an effective to-be-displayed image a1 (white area) and an edge transition display image a2 (gray area).
It can be seen that the edge transition display image a2 also has invalid display data, and therefore, in order to reduce the transmission bandwidth occupied by the invalid display data, after the first valid display image is obtained, the data processing module 110 may perform smoothing processing on the edge transition display image according to a preset edge smoothing algorithm to obtain a third valid image to be displayed in the edge transition display image.
Finally, the data processing module 110 may determine the second effective display image and the third effective display image as effective images to be displayed. Illustratively, fig. 5 is a schematic diagram of another effective image to be displayed according to an embodiment of the present invention. As shown in fig. 5, the valid data to be displayed may include areas indicated by a51 and a52, and it is seen that invalid display data is significantly reduced. The data transmission method provided by the embodiment of the invention can further improve the data transmission efficiency and the utilization rate of the data transmission channel, and simultaneously, the data transmission rate can be reduced due to the effective reduction of the data to be transmitted, thereby not only being beneficial to improving the accuracy and the stability of data transmission, but also reducing the complicated design of data transmission equipment for adapting to high transmission rate, and further reducing the design cost.
In the embodiment of the present invention, the transmission path 120 may include a plurality of paths for transmitting data, that is, N transmission paths, where N is a positive integer.
After obtaining the effective transmission data, the data processing module 110 may input each row of effective data to be transmitted into the storage module through the N transmission paths according to a preset data transmission rule.
In some embodiments, the storage module 130 includes N storage submodules, and one end of each of the N paths is connected to the data processing module in parallel, where the connection node is located in the middle of the N paths, and the other ends of the N paths are respectively connected to the N storage submodules in the storage module.
Specifically, the data processing module 110 sequentially inputs first effective data to be transmitted included in each line of effective data to be transmitted into at least one path on one side of the connection node, and sequentially inputs second effective data to be transmitted included in each line of effective data to be transmitted into at least one path on the other side of the connection node; at least one path inputs the received effective data to be transmitted into the storage module.
As a specific example, fig. 6 shows that the embodiment of the present invention provides a data transmission flow diagram. (where the data processing module 110 and the scanning module 140 are not shown), in the transmission path 120, a paths are located on one side of the connection node, and b paths are located on the other side of the connection node, where the sum of a and b is N. The data processing module 110 transmits the effective data to be displayed to the connection node, and then the effective data to be transmitted are sequentially input to the storage module from the connection node to both sides.
As a specific example, the memory submodule may have a memory with a memory function, such as a D Flip-Flop (DFF).
In order to avoid a large time delay in data transmission between the transmission paths and improve the overall transmission speed of data, the storage module 130 may further include N buffer sub-modules, and the N buffer sub-modules are respectively connected to the N storage sub-modules. That is, the storage module 130 may be provided with a Buffer (Buffer) corresponding to each storage sub-module, i.e., the BUF shown in fig. 6.
Specifically, in the storage module 130, at least one storage submodule corresponding to at least one path receives valid data to be transmitted sent by at least one path; when the transmission of a row of effective data to be transmitted is finished, at least one storage submodule inputs the effective data to be transmitted into at least one buffer submodule corresponding to at least one storage submodule.
After the transmission of the effective data to be displayed in the storage module 130 is completed, the scanning module 140 is configured to obtain each line of effective data to be transmitted from the storage module according to a preset scanning rule, and send the line of effective data to be transmitted to a display screen of the data display device.
In some embodiments, in order to reduce data that needs to be transmitted, an image to be displayed is split into valid data to be displayed and invalid data to be displayed in an invalid display area according to the shape of the display area, and thus, in conjunction with the shape of the display area, there may be a difference in the data amount of the valid data to be displayed between different lines. In order that the scanning module can accurately send the effective data to be displayed into the display area of the display screen, a preset data address lookup Table (Look Up Table) may be preset, and the scanning module 140 may determine the scanning timing sequence of the data transmitted by each row of effective bands according to the preset data address lookup Table; and according to the scanning time sequence, the effective data to be transmitted are accurately sent to a display area of a display screen in the data display equipment.
In addition, in order to set the scanning timing sequence of the scanning module more flexibly, a preset timing sequence scanning function may be preset, and the scanning module 140 may scan each line of the effective band transmission data according to the preset timing sequence scanning function, and accurately send the effective data to be transmitted to a display area of a display screen in the data display device.
In some embodiments, the preset scanning timing function may include a preset scanning coefficient, and the preset scanning timing function corresponding to different display shapes may be obtained by modifying only the preset scanning coefficient, so that the data transmission device provided in the embodiments of the present invention is more flexible.
According to the data transmission device provided by the embodiment of the invention, before the image to be displayed is input into the storage module, firstly, the effective image to be displayed in the data transmission device is determined by combining the display resolution of the data transmission device, and then, only the effective image to be displayed is transmitted, so that the data bandwidth utilization rate is improved; because the data volume needing to be transferred out is effectively reduced, the transmission rate can be effectively reduced when the display image is input into the storage module, and the accuracy and the stability of data transmission are improved. And then, the scanning module acquires each line of the effective data to be transmitted from the storage unit according to a preset scanning rule and sends the effective data to be transmitted to the data display equipment, and because the data volume of the effective image to be displayed is effectively reduced relative to the data volume of the image to be displayed, the preset scanning rule needs to be determined corresponding to the effective image to be displayed, so that the effective image to be displayed is accurately displayed on the data display equipment.
