Detailed Description
The present invention will be described in further detail 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 limitation. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
It should be noted that, for the sake of brevity, this description does not exhaust all alternative embodiments, and it should be understood by those skilled in the art after reading this description that any combination of features may constitute an alternative embodiment as long as the features are not mutually inconsistent.
The following provides a detailed description of various embodiments of the invention.
Fig. 1 is a flowchart of a multi-channel-based image display method according to an embodiment of the present invention. As shown in the figure, the multi-channel-based picture display method is applied to a terminal device, especially a terminal device using an ink screen for display, namely, an ink screen display device, and includes steps S110 to 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 adaptive refresh frequencies corresponding to different element types are different and the corresponding data paths 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 conventional ink screen display devices, the processor 110 typically communicates data with the display controller 120 via a data path. In both the hardware architecture shown in fig. 2 and the hardware architecture of a general data path, the basic display process is that the processor 110 processes data in the operation process of the ink screen display device to generate corresponding screen data, sends the screen data to the display controller 120, and the display controller 120 controls the ink screen 130 to display according to the received screen 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 currently running application, and according to the operation of a user, the running application or the application window in the running application changes, and the picture needs to be regenerated correspondingly. 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 displayed picture corresponds to one frame of picture data. For different applications, different components and color combination modes are provided, 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 contents, and the display controller completes the picture display process on the ink screen finally after processing based on the colored frame picture data.
The display contents in the application windows are different, and correspondingly required data transmission modes and refresh modes are also different, for example, the display contents corresponding to the video application have high requirements on the transmission rate of data but have low requirements on 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 screen may be formed by combining different types of application windows, the same data transmission channel is used for transmitting the whole display screen in the ink screen, and the same refresh mode is correspondingly used for refreshing and displaying, so that a situation that the display requirement conflicts with the display requirement of a certain type of display content, for example, video jamming, and handwriting is not followed during handwriting may occur.
The element types are divided according to the adaptive refresh frequency, and an exemplary division mode is to divide the element types into high-frequency refresh elements and low-frequency refresh elements. The high-frequency refreshing element refers to a content element which has higher requirements on refreshing frequency during refreshing, such as handwriting and a jumping tail digit in a high-precision stopwatch. The low-frequency refresh element refers to a content element with a low requirement on refresh frequency during refresh, such as a video played at 30 frames/second or even lower speed, an electronic book that turns pages at a certain time interval, and the like. Overall, the adaptive refresh frequency corresponding to the high frequency refresh element is higher than that of the low frequency refresh element. The following description is exemplarily made by dividing the data into two element types, where the corresponding data paths are the first data path and the second data path, respectively. Of course, in the actual process, there may be more classifications, such as further increasing the classification of the mid-frequency refresh elements. It should be noted that the high frequency refresh element or the low frequency refresh element is only used for exemplarily describing the classification definition, and the element types are divided into the first element type, the second element type and the third element type based on the classification based on the adaptive refresh frequency, or other naming methods, which do not depart from the design concept of the present solution. The processor may specifically be according to an application type of the application window, for example, a window corresponding to the video application is a low-frequency refresh element, and a character window of the high-precision stopwatch is a high-frequency refresh element; and for example, the element type of the display element is determined according to the type of the received interactive 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 one page turning operation detected at a long time interval is a low-frequency refreshing element. That is, the high frequency refresh element includes handwriting elements and the low frequency refresh element includes video frame picture elements.
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: and the processor sends the display signals to the display controller through corresponding data paths respectively.
And correspondingly generating different display signals corresponding to different display requirements of the high-frequency refreshing element and the low-frequency refreshing element, and sending the different display signals to the display controller through different data channels. In the specific sending process, according to the display requirements of the high-frequency refreshing elements and the low-frequency refreshing elements, the used format and protocol are correspondingly adopted for data transmission, and in the principle of overall processing, the data packets of the high-frequency refreshing elements are small, and the sending frequency is high; the data packet of the low-frequency refreshing element is large, and the sending frequency is low. The data corresponding to two different formats and protocol codes are transmitted through different data paths respectively, namely 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 method of the same type of combination processing is that the number of the obtained display signals is the same as the type of the current element corresponding to the display element in the picture to be displayed. Of course, each application window may be sent independently, but the data path sent is acknowledged by type.
Of course, in the actual processing process, there may be a case where only the high frequency refresh element or only the low frequency refresh element occurs, and in this case, the implementation of the scheme is not affected, which is equivalent to that one of the data paths does not perform data transmission, and the display controller performs processing according to the received data. In addition, each signal correspondingly carries display position information so as to finally combine and generate a picture adaptive to the ink screen.
Step S140: and the display controller generates a spliced picture according to the display signal.
And analyzing the display signals received from different data paths according to corresponding formats and protocols, and combining and generating a spliced picture according to corresponding display position information. The display position information may specifically be absolute position information, that is, corresponding display coordinates; or may be relative position information such as an arrangement. Corresponding to the arrangement, step S140 may include steps S142 to S144.
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 sequence frames obtained by splitting.
The arrangement mode refers to a relative position relationship between the first display signal and the second display signal, for example, the display contents corresponding to the first display signal and the second display signal are arranged in a left-right direction, a top-bottom direction or a picture-in-picture direction. As shown in fig. 3, the first display area 131 is used for displaying the second display signal, and the second display area 132 is used for displaying the first display signal. 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, when online learning is performed using an ink screen display device, the online learning video window may be displayed in a partial region (i.e., display corresponding to the second display signal), and learning records may be performed in a partial region according to the learning content to generate a learning note (i.e., display corresponding to the first display signal). Therefore, the display method can adapt to the scene of mixed display requirements, and can refresh and display different display contents in a targeted manner, thereby avoiding the situation of poor display effect caused by conflict between the refresh mode and the refresh mode of a certain display content.
When the display signals are transmitted, the data sizes corresponding to different data paths may be different, and for the display signals in the same picture to be displayed, the receiving time of the display controller may be different in sequence. In the specific splicing process, the display controller can finish the corresponding splicing when receiving a display signal until a spliced picture is generated by combination; or after receiving all the display signals corresponding to one to-be-displayed picture, combining 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, cutting scaling and shaking.
The initial picture is the color picture obtained by directly splicing the display signals sent by the processor, and the gray picture which can be displayed by the ink screen or the color picture with less order can be obtained by correspondingly processing various pictures.
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 can be implemented by steps S151 to S153:
step S151: and the display controller sets the area display mode of the ink screen according to the 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 regional display mode.
Step S153: and the display controller controls the ink screen to display according to the waveform data.
Step S151 to step S153 may be regarded as determining a corresponding refresh mode according to the first display signal and the second display signal (for example, if the display area of the second display signal may be a video to be displayed, a refresh policy of the video is used, if the display area of the first display signal may be handwriting to be displayed, the refresh rate is increased, the delay is reduced, and in addition, the refresh may be stopped for the display area without picture update, and only the other area with changed part is updated), generating corresponding waveform data in the corresponding display area according to the refresh mode and the spliced picture, and controlling the process of displaying the ink screen according to the waveform data. The specific generation of the waveform data and the control of the ink screen for 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 image display method 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 through one of the data paths.
Based on the control signal, step S130 may 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 may control a content ratio, a relative position relationship, a display mode, a preprocessing strategy, and the like corresponding to the display signal, and the control signal is transmitted through the corresponding third data path. The third data path for sending the control signal may be an independent data path or a data path multiplexed with a certain display signal, and if the third data path is multiplexed, the control signal and the display signal are distinguished by different transmission protocols. The control signal is mainly used for indicating a 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, richer display effect can be realized at ink screen display equipment.
The multi-channel-based picture display method is used for ink screen display equipment, the ink screen display equipment 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 the element type of each display element, wherein the element types comprise at least two types, the adaptive refresh frequency corresponding to different element types is different, and the corresponding data paths are different; the processor combines the display elements according to the identified 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, the targeted refreshing is carried out according to the local picture type characteristic of the picture to be displayed in a proper mode, so that the negative effects of display blocking, interaction response delay and the like are avoided, and the picture display effect of the ink screen is improved.
