Detailed Description
The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are for purposes of illustration and not of limitation. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.
It should be noted that, for the sake of brevity, this specification is not exhaustive of all of the alternative embodiments, and after reading this specification, one skilled in the art will appreciate that any combination of features may constitute an alternative embodiment as long as the features do not contradict each other.
The following describes various embodiments of the present invention in detail.
Fig. 1 is a flowchart of a multi-channel-based image display method according to an embodiment of the present invention. The multi-channel-based picture display method is used for terminal equipment, particularly for terminal equipment using an ink screen for display, namely the ink screen display equipment, and as shown in the figure, the multi-channel-based picture display method comprises the steps of S110-S150:
step S110: the processor acquires display elements forming a picture to be displayed, and confirms element types of each display element, wherein the element types comprise at least two types, and the adaptation refresh frequencies and the corresponding data paths corresponding to different element types are different.
The hardware architecture of the ink screen display device in this embodiment is shown in fig. 2, and includes a processor 110, a display controller 120, and an ink screen 130, where the processor 110 performs data transmission through at least two different data paths (a first data path and a second data path are shown in fig. 2). In existing ink screen display devices, the processor 110 typically communicates data with the display controller 120 via a data path. Whether the hardware architecture shown in fig. 2 or the hardware architecture of a common data path, the basic display process is that the processor 110 processes data in the operation process of the ink screen display device, generates corresponding picture data, sends the picture data to the display controller 120, and the display controller 120 controls the ink screen 130 to display according to the received picture data.
In the display process of the ink screen display device, a processor of the ink screen display device generates a display picture according to an application window of a current running application, and the running application or the application window in the running application changes according to the operation of a user, so that the picture is correspondingly required to be regenerated. For the ink screen display device, the content to be displayed after the currently displayed picture corresponds to the picture to be displayed, and each display picture corresponds to one frame of picture data. For different applications, the different components and the color combination modes are respectively arranged, the picture formed by the method is generally a picture with rich and various colors, namely, the original frame picture data correspondingly carries rich color content, and the display controller completes the picture display process on the ink screen after processing the color frame picture data.
The display content in the application window is different, and the corresponding required data transmission mode and refreshing mode are also different, for example, the display content corresponding to the video application has high requirement on the data transmission rate, but has low requirement on the delay; for example, the input content corresponding to the hand editing application has low requirements on the transmission rate of data, but has high requirements on delay. However, in the ink screen display device, the display frames may be formed by combining different types of application windows, the same data transmission channel is used for transmitting the whole display frame in the ink screen, and the same refresh mode is correspondingly used for refreshing and displaying, so that the situation that the display requirements of a certain type of display content conflict with each other, for example, video is stuck, and handwriting is not in contact with hands during handwriting may occur.
The element types are divided according to the adaptive refresh frequency, and one exemplary division is into high-frequency refresh elements and low-frequency refresh elements. The high-frequency refreshing element refers to a content element with high requirements on refreshing frequency during refreshing, such as handwriting of handwriting and the tail number of jitter in a high-precision stopwatch. The low-frequency refresh element refers to a content element requiring a low refresh frequency at the time of refresh, for example, a video played at a speed of 30 frames/second or less, an electronic book in which pages are turned at intervals of a certain time, or the like. Overall, the adaptation refresh frequency corresponding to the high frequency refresh element is higher than the low frequency refresh element. The following description will be exemplarily made with two element types divided into a first data path and a second data path, respectively, corresponding to the data paths. Of course, in the actual process, there may be more classifications, for example, further increasing the classification of intermediate frequency refresh elements. In addition, it should be noted that the high-frequency refreshing element or the low-frequency refreshing element is only used for exemplary description classification definition, and on the basis of classifying based on the adaptive refreshing frequency, the element types are classified into a first element type, a second element type and a third element type, or other naming manners, without departing from the design idea of the scheme. The processor can specifically determine that a window corresponding to the video application is a low-frequency refreshing element and a character window of the high-precision stopwatch is a high-frequency refreshing element according to the application type of the application window; and for example, the element type of the display element is confirmed according to the type of the received interaction data, for example, handwriting display corresponding to the user writing operation detected by the touch module is a high-frequency refreshing element, and a picture corresponding to the page turning operation which can be detected once only for a long time is a low-frequency refreshing element. I.e. the high frequency refresh element comprises a writing element and the low frequency refresh element comprises a video frame picture element.
Step S120: and combining the display elements according to the confirmed current element types to generate display signals corresponding to the number of the current element types.
Step S130: the processor sends the display signals to the display controller through corresponding data paths respectively.
Different display signals are correspondingly generated corresponding to different display requirements of the high-frequency refreshing element and the low-frequency refreshing element and are sent to the display controller through different data paths. In a specific transmission process, according to the display requirements of the high-frequency refreshing element and the low-frequency refreshing element, the data transmission is correspondingly carried out by adopting a used format and protocol, and in the whole processing principle, the data packet of the high-frequency refreshing element is smaller and the transmission frequency is higher; the data packet of the low-frequency refreshing element is larger, and the sending frequency is lower. The data corresponding to two different formats and protocols are transmitted through different data paths respectively, which is equivalent to the fact that a plurality of signal channels are arranged between a processor and a display controller in the ink screen display device, and display elements in a display picture are not all combined and transmitted before transmission, but are transmitted according to types. The same type of application windows can be combined and sent, and different types of application windows are combined according to types and then are independently sent. Of course, each application window may also be sent independently, but the data path sent is acknowledged by type.
Of course, in the actual processing, only the high-frequency refreshing element or only the low-frequency refreshing element may occur, and this case does not affect the implementation of the scheme, which is equivalent to that one of the data paths does not perform data transmission, and the display controller only needs to perform processing according to the received data. In addition, each signal carries display position information correspondingly so as to finally combine and generate a picture which is suitable for the ink screen.
Step S140: and the display controller generates a spliced picture according to the display signal.
Corresponding to the display signals received from different data paths, analyzing according to the corresponding formats and protocols, and generating a spliced picture according to the corresponding display position information combination. The display position information may specifically be absolute position information, that is, corresponding display coordinates; but also relative position information, such as an arrangement. Step S140 may include steps S142-S144 corresponding to the arrangement.
Step S142: the display controller splits the sequence frame according to the display signal.
Step S143: and the display controller generates an initial picture which is adaptive to the size of the ink screen according to the corresponding arrangement mode of the split sequence frames.
The arrangement mode refers to a relative positional relationship between the first display signal and the second display signal, for example, a left-right arrangement, a top-bottom arrangement, or a picture-in-picture arrangement of display contents corresponding to the first display signal and the second display signal. As shown in fig. 3, the first display area 131 is used for displaying the second display signals, and the second display area 132 is used for displaying the first display signals. As shown in fig. 4, the third display area 133 is used for displaying the first display signal, and the fourth display area 134 is used for displaying the second display signal. In this implementation, for example, the on-line learning is performed using an ink screen display device, and the display of the on-line learning video window (i.e., the display corresponding to the second display signal) may be performed in a partial region, and in addition, the learning record is performed according to the learning content in a partial region, so as to generate the learning note (i.e., the display corresponding to the first display signal). Therefore, the method and the device can adapt to targeted refreshing display of different display contents under the mixed display requirement scene, and avoid the situation that the refreshing of certain display content conflicts with the refreshing mode, so that the display effect is poor.
When the display signals are transmitted, the data sizes corresponding to different data paths may be inconsistent, and the receiving time of the display controllers may be different for the display signals in the same picture to be displayed. In a specific splicing process, the display controller can finish corresponding splicing after receiving a display signal until a spliced picture is generated by combining; or after receiving all display signals corresponding to one picture to be displayed, the display signals can be combined once to generate a spliced picture.
Step S144: and preprocessing the initial picture to obtain a spliced picture, wherein the preprocessing comprises at least one of gray level conversion, clipping, scaling and dithering.
The initial picture is a color picture obtained by directly splicing display signals sent by the processor, and corresponds to a gray picture which is required to be processed to be displayed by the ink screen or a color picture with a small number of steps.
Step S150: and the display controller controls the display area corresponding to the ink screen to display according to the corresponding display mode according to the picture areas corresponding to different display signals in the spliced picture.
In the specific display process, step S150 may be implemented through steps S151 to S153:
step S151: and the display controller sets the area display mode of the ink screen according to element type distribution corresponding to the spliced picture.
Step S152: and the display controller generates waveform data according to the spliced picture and the corresponding area display mode.
Step S153: and the display controller controls the ink screen to display according to the waveform data.
Step S151-step S153 may be considered to be a process of confirming a corresponding refresh mode according to the first display signal and the second display signal (for example, the display area of the second display signal may be a refresh policy for displaying video, the display area of the first display signal may be a refresh policy for displaying handwriting, the refresh rate is increased and the delay is reduced, or the refresh may be stopped for a display area without picture update, and only a region with another part changed is updated), generating corresponding waveform data in the corresponding display area according to the refresh mode and the spliced picture, and controlling the display of the ink screen according to the waveform data. The specific generation of waveform data and the control of the ink screen to display according to the waveform data are basic implementations in the field of ink screen display, and are not described herein.
In a specific implementation process, the method for displaying the picture further includes:
step S121: the processor receives the control instruction and correspondingly generates a control signal.
Step S122: the processor sends the control signal to the display controller via one of the data paths.
On the basis of the control signal, step S130 may specifically further include step S131:
step S131: and the display controller generates a spliced picture according to the display signal based on the control signal.
The control signal includes at least one of a display mode control signal and a mosaic arrangement control signal.
The control signal can control the content proportion, the relative position relation, the display mode, the preprocessing strategy and the like corresponding to the display signal, and the control signal is sent through the corresponding third data path. The third data path for transmitting the control signal may be an independent data path or may be a data path multiplexed with a certain display signal, and if multiplexed, the control signal and the display signal may be distinguished by different transmission protocols. The control signal is mainly used for indicating the display control strategy of the display controller, and the whole processing process of the display picture is basically the same on the basis of confirming the display control strategy. Through the control signal, a richer display effect can be realized on the ink screen display device.
The multi-channel-based picture display method is used for the ink screen display device, the ink screen display device comprises a processor, an ink screen and a display controller, the display controller is used for controlling the ink screen to display, and the processor is connected with the display controller through at least two data paths; the picture display method comprises the following steps: the processor acquires display elements forming a picture to be displayed, and confirms element types of each display element, wherein the element types comprise at least two types, and the adaptation refresh frequencies corresponding to different element types are different and the corresponding data paths are different; the processor combines the display elements according to the confirmed current element types to generate display signals corresponding to the number of the current element types; the processor sends the display signals to the display controller through corresponding data paths respectively; the display controller generates a spliced picture according to the display signal; and the display controller controls the display area corresponding to the ink screen to display according to the corresponding display mode according to the picture areas corresponding to different display signals in the spliced picture. According to the scheme, targeted refreshing is carried out according to the local picture type characteristic of the picture to be displayed in a proper mode, so that negative effects such as display blocking and interaction response delay are avoided, and the picture display effect of the ink screen is improved.
