Description

显示数据的传输方法和电子装置 Transmission method and display data of the electronic device

技术领域 FIELD

[0001] 本发明涉及显示技术,特别涉及一种显示数据的传输方法和电子装置。 [0001] The present invention relates to display technology, and particularly relates to a transmission method and an electronic apparatus for displaying data.

背景技术 Background technique

[0002]移动产业处理器接口(Mobile Industry Processor Interface,简称“MIPI ”)是面向移动设备的显示标准,包含视频模式(Display Serial Interface Video Mode,以下简称“VIDEO MODE”)和命令模式(Display Serial Interface Command Mode,以下简称“COMMAND MODE”)两种显示模式。 [0002] Mobile Industry Processor Interface (Mobile Industry Processor Interface, referred to as "MIPI") is a standard for mobile devices, comprising a video mode (Display Serial Interface Video Mode, hereinafter referred to as "VIDEO MODE") and a command mode (Display Serial Interface Command mode, hereinafter referred to as "COMMAND mODE") two display modes.

[0003] 视频模式与传统RGB接口相似,主机需要持续刷新显示器。 [0003] Video RGB interface similar to the conventional mode, the host needs to continue to refresh the display. 由于不使用专用的数据信号传输同步信息,控制信号和RGB数据是以报文的形式通过MIPI总线传输的,因此显示器就不需要帧缓冲器,主机需要定期刷新显示器。 Since no dedicated data transmission synchronization signal information, the control signal and the RGB data packets are transmitted over the bus in the form of MIPI, and therefore do not need the display frame buffer, the host needs to periodically refresh the display.

[0004] 命令模式下,MIPI总线控制器使用显示命令来向显示器发送像素数据流。 [0004] The command mode, MIPI bus controller transmits display command using the pixel data stream to the display. 显示器有一个全帧长的帧缓冲器来存储所有的像素数据。 Monitor has a frame length of a full frame buffer to store all the pixel data. 一旦数据被放在显示器的帧缓冲器中,定时控制器就从帧缓冲器中取出数据,并自动把它们显示在屏幕上。 Once the data is placed in a display frame buffer, the timing controller to retrieve data from the frame buffer, and automatically displays them on the screen. MIPI总线控制器不需要定期刷新显示器。 MIPI bus controller does not require periodic refresh the display.

[0005] 两种模式单独使用各有优缺点。 [0005] separate modes have advantages and disadvantages. 视频模式下的显示器无须帧缓冲器,可以节省成本;但主机定期以高速模式发送视频报文却消耗了大量的平均能量。 Without display of the video frame buffer mode, costs can be saved; but the host regularly transmits video packets in a high speed mode it consumes a large amount of average energy. 在命令模式下,如果显示器显示的是静态图片即画面未有变化和更新时,MIPI控制器是不会传输数据的,这样可以降低电子设备的功耗,尤其用户在电子设备上不切换显示内容的时间越长,那么功耗越低,但缺点是成本较高。 In the command mode, if the display of a static image that is displayed when the screen changes and updates No, the MIPI controller is not transmitting data, which can reduce the power consumption of the electronic device, in particular, the user does not switch the display contents on the electronic device the longer the time, the lower the power consumption, but the disadvantage is the higher cost.

具体实施方式 detailed description

[0023] 为使本发明的目的、技术方案和优点更加清楚,下面将结合附图对本发明的各实施方式进行详细的阐述。 [0023] To make the objectives, technical solutions, and advantages of the present invention will become more apparent below with reference to the drawings embodiments of the present invention in detail. 然而,本领域的普通技术人员可以理解,在本发明各实施方式中,为了使读者更好地理解本申请而提出了许多技术细节。 However, those of ordinary skill in the art will be appreciated, in the embodiments of the present invention, in order to make the reader a better understanding of the present application proposed many technical details. 但是,即使没有这些技术细节和基于以下各实施方式的种种变化和修改,也可以实现本申请各权利要求所要求保护的技术方案。 However, without these technical details and various changes and modifications based on the following embodiments, the present application may be realized by the claims claimed technical solution.

[0024] 本发明的第一实施方式涉及一种显示数据的传输方法。 [0024] In a first embodiment of the present invention relates to a method for transmitting display data. 该方法可用于智能手机或平板电脑(PAD),该方法可以采用两种模式在中央处理器和显示设备之间传输显示数据,并且满足一定的预设条件的情况下,可以实现两种模式之间的切换。 This method can be used for a smart phone or tablet (the PAD), which may be used in two modes in the case of the central processor and display the display data transfer between devices, and to meet certain preset condition, the two modes can be realized switching between. 第一模式和第二模式为视频模式(VIDEO MODE)或命令模式(COMMAND MODE)中的一种,并且第一模式与第二模式不同。 The first and second modes is a video mode (VIDEO MODE) or the command mode (COMMAND MODE) of one, and the first and second modes are different.

[0025] 以下以第一模式为命令模式(COMMAND MODE),第二模式为视频模式(VIDEO MODE)为例进行说明,具体流程图如图1所示,包含以下步骤: [0025] In the first mode is a mode command (COMMAND MODE), the second mode is a video mode (VIDEO MODE) as an example, the specific flow chart shown in Figure 1, comprising the steps of:

[0026] 步骤101,采用命令模式(COMMAND MODE)在中央处理器和显示设备之间传输显示数据。 [0026] Step 101, using the command mode (COMMAND MODE) the display data transfer between the central processor and the display device.

[0027] 步骤102,判断是否满足预设的第一切换条件;若是,则执行步骤103 ;若否,则返回执行步骤101。 [0027] Step 102 determines whether a first predetermined switching condition is satisfied; if yes, execute step 103; if not, execution returns to step 101.

[0028] 步骤103,采用视频模式(VIDEO MODE)在中央处理器和显示设备之间传输显示数据。 [0028] Step 103, using the video mode (VIDEO MODE) the display data transfer between the central processor and the display device.

[0029] 步骤104,判断是否满足预设的第二切换条件,若是,则执行步骤101 ;若否,则返回执行步骤103。 [0029] Step 104 determines whether a second predetermined switching condition is satisfied, if yes, execute step 101; if not, returns to step 103.

[0030] 具体地说,预设的第一切换条件和第二切换条件可以为触发设备接收的不同的模式切换触发指令。 [0030] Specifically, a first predetermined switching condition and the second switching handover trigger condition may be different instruction mode trigger device receives. 比如,触发设备可以为移动终端的触摸屏,触发指令为进入省电模式或退出省电模式,预设的第一切换条件为触发设备接收到“退出省电模式”的指令,预设的第二切换条件为触发设备接收到“进入省电模式”的指令。 For example, the trigger device may be a touch screen of the mobile terminal, the triggering instruction to enter or exit a power saving mode, the power saving mode, the first switching condition preset trigger device receives an instruction to "exit the power saving mode", the predetermined second switching condition to trigger the device receives the instruction "enter the power saving mode". 当前正在采用命令模式在中央处理器和显示设备之间传输显示数据,如果触发设备接收到“退出省电模式”的指令时,则切换到采用视频模式(VIDEO MODE)在中央处理器和显示设备之间传输显示数据;否则,仍采用命令模式在中央处理器和显示设备之间传输显示数据。 Command mode is currently using to transmit the display data between a central processor and a display device, if the device receives an instruction to trigger "exit the power saving mode" is switched to the central processor and the display device using the video mode (VIDEO MODE) data transmission between the display; otherwise, show still use command mode data transmission between the central processor and the display device. 当前正在采用视频模式(VIDEO MODE)在中央处理器和显示设备之间传输显示数据,如果触发设备接收到“进入省电模式”的指令时,则切换到采用命令模式在中央处理器和显示设备之间传输显示数据;否则,仍采用视频模式(VIDEO MODE)在中央处理器和显示设备之间传输显示数据。 Currently using video mode (VIDEO MODE) transmit the display data, if the apparatus receives an instruction to trigger the "power saving mode", the switching to the central processor and the display device using the command mode between the central processor and the display device data transmission between the display; otherwise, still using the video mode (vIDEO mODE) the display data transfer between devices in the central processor and display.

[0031] 与现有技术相比,本实施方式根据触发设备接收的不同模式切换触发指令,使用户可以根据电子装置的实际使用情况,实现显示数据的传输在两种模式之间的切换,这样不仅降低了电子装置的功耗,提高了电子装置的电池续航能力,而且进一步地提高了用户体验。 [0031] Compared with the prior art, the present embodiment depending on the mode switching trigger device receives a triggering instruction, so that the user can actually use the electronic device, to realize the transmission of the display data switching between the two modes, so not only reduces the power consumption of electronic devices, improve the battery life of electronic devices, but also further improve the user experience.

[0032] 此外,值得一提的是,如果采用命令模式(COMMAND MODE)在中央处理器和显示设备之间传输显示数据,显示数据还可以以预定的显示色彩在显示设备上显示,可以进一步降低功耗,提高电子装置的电池续航能力。 [0032] In addition, it is worth mentioning that, if the command mode (COMMAND MODE) the display data transfer between the central processor and the display apparatus, display data may also be displayed in a predetermined display color on the display device can be further reduced power consumption and improve battery life of the electronic device. 具体地说,由于采用命令模式(COMMAND MODE)在中央处理器和显示设备之间传输显示数据,即此时显示设备的显示数据不经常改变,电子装置处于低功耗状态。 Specifically, since the command mode (COMMAND MODE) in the transmission between the central processor and a display device for displaying data, i.e., data is displayed in the display device does not change often, the electronic device is in a low power state. 进一步地显示数据以预定的显示色彩在显示设备上显示,比如,整个显示设备的显示方式可以为黑底单色显示,即显示设备背光面为黑色,需要显示的文字、数字等信息采用单色显示,单色显示的色彩可以为白色、红色、黄色或绿色,显示色彩的选择这里不作具体限定。 Further, the display data in a predetermined display color on the display device, for example, the entire display device can be displayed for the black monochrome display, i.e. a display device backlight surface is black, need to display characters, figures and other information monochrome display, monochrome display color may be white, red, yellow or green, the display color choice here is not particularly limited.

[0033] 本发明的第二实施方式涉及一种显示数据的传输方法。 [0033] The second embodiment of the present invention relates to a method for transmitting display data. 第二实施方式与第一实施方式大致相同,主要区别之处在于:在第一实施方式中,预设的第一切换条件和预设的第二切换条件为触发设备接收的不同的模式切换触发指令。 The second embodiment is substantially the same as the first embodiment, the main difference is that: in a first embodiment, the first switching condition preset and the preset second condition is a different mode switching trigger received handover trigger device instruction. 而在本发明第二实施方式中,通过对电池电量的检测判断在命令模式和视频模式(VIDEO MODE)之间进行切换,降低了电子装置的功耗,提高了电池的续航能力。 In the second embodiment of the present invention, by detecting the battery charge is determined between the command mode and video mode (VIDEO MODE) to switch, reducing the power consumption of the electronic device improves the battery life.

[0034] 以下以第一模式为视频模式(VIDEO MODE),第二模式为命令模式(COMMAND MODE)为例进行说明,但第一模式和第二模式的具体选择并不仅限于此。 [0034] In the first mode is a video mode (VIDEO MODE), the second mode is a mode command (COMMAND MODE) as an example, but the particular choice of a first mode and the second mode is not limited thereto.

[0035] 若第一模式为视频模式(VIDEO MODE),第二模式为命令模式(COMMAND MODE),则预设的第一切换条件为电池电量低于预设的第一电量阈值;预设的第二切换条件为电池电量高于预设的第二电量阈值;其中,第一电量阈值小于或等于第二电量阈值。 [0035] When the first mode is a video mode (VIDEO MODE), the second mode is a mode command (COMMAND MODE), the first switching condition is a predetermined battery charge is below a first predetermined threshold; preset a second switching condition of battery charge is higher than a predetermined second threshold value; wherein, a first quantity equal to or less than the second threshold value electric quantity threshold.

[0036] 具体地说,当前采用视频模式(VIDEO MODE)在中央处理器和显示设备之间传输显示数据,若电池电量低于第一电量阈值,则切换到采用命令模式(COMMAND MODE)在中央处理器和显示设备之间传输显示数据;若电池电量高于第一电量阈值,则仍然采用视频模式(VIDEO MODE)在中央处理器和显示设备之间传输显示数据。 [0036] Specifically, using the current video mode (VIDEO MODE) in the central processor and display the display data transfer between devices, if the battery is below a first threshold amount, using the command mode is switched to (COMMAND MODE) in the central the display data transfer between a processor and a display device; if the battery charge is higher than a first threshold value, using the still video mode (vIDEO mODE) the display data transfer between devices in the central processor and display. 当前采用命令模式(COMMANDMODE)在中央处理器和显示设备之间传输显示数据,若电池电量高于第二电量阈值,则切换到采用视频模式(VIDEO MODE)在中央处理器和显示设备之间传输显示数据;若电池电量低于第二电量阈值,则仍然采用命令模式(COMMAND MODE)在中央处理器和显示设备之间传输显示数据。 Transmit the display between the central processor and a display device using the current command data mode (COMMANDMODE), if the battery charge is higher than a second threshold value, the mode is switched to the use of video (VIDEO MODE) transmission between the central processor and the display device display data; if the battery is below a second threshold amount, using the still mode command (cOMMAND mODE) the display data transfer between devices in the central processor and display.

[0037] 举例来说,假设第一电量阈值和第二电量阈值相等,均为60%。 [0037] For example, if a first charge threshold value and is equal to the second power threshold is 60%. 当预设第一切换条件为电池电量低于预设的第一电量阈值时,即当电池电量低于60%时,满足预设的第一切换条件,该电子装置采用命令模式(COMMAND MODE)在中央处理器和显示设备之间传输显示数据。 When the first switching condition is a predetermined battery charge is below a first predetermined threshold value, i.e. when the battery is below 60%, satisfies the preset first switching condition, the electronic device using the command mode (COMMAND MODE) the display data transfer between the central processor and the display device. 当第二切换条件为电池电量高于预设的第二电量阈值时,即当电子装置电池电量高于60%时,满足预设的第二切换条件,该电子装置采用视频模式(VIDEO MODE)在中央处理器和显示设备之间传输显示数据。 When the second switching condition of the second battery is higher than a preset threshold amount, i.e., when the electronic device battery is higher than 60%, satisfies a predetermined second switching condition, the electronic device using the video mode (VIDEO MODE) the display data transfer between the central processor and the display device.

[0038] 由于电子装置在实际工作过程中,电池电量并不精确为60 %,而是在60 %上下很小的范围(比如59%〜61% )内波动,由于电池电量的波动,若将第一电量阈值与第二电量阈值均设置为60%,则电子装置显示数据的传输模式会在命令模式(COMMAND MODE)和视频模式(VIDEO MODE)之间进行多次的来回切换会增加电子装置的功耗。 [0038] Since the electronic device in the actual operation, the battery is not exactly 60%, but fluctuates within a small range of 60% up and down (for example 59% ~61%), due to fluctuations in battery, if a first charge threshold value and the second threshold quantity are set to 60%, the electronic device displays the data transfer mode will switch back and forth several times to increase the electronic device between a command mode (cOMMAND mODE) and a video mode (vIDEO mODE) power consumption.

[0039] 为了避免上述情况的出现,可以采用施密特触发器的原理,设定第一电量阈值小于第二电量阈值,比如,第一电量阈值为60%,第二电量阈值可以为70%。 [0039] To avoid the above situation, the principles may be employed Schmitt trigger, setting a first power threshold is less than the second power threshold value, for example, a first power threshold is 60%, the second power threshold may be 70% . 当电池电量低于60%时,满足预设的第一切换条件,该电子装置采用命令模式(COMMAND MODE)在中央处理器和显示设备之间传输显示数据。 When the battery is less than 60%, satisfies the preset first switching condition, the electronic device using the command mode (COMMAND MODE) the display data transfer between the central processor and the display device. 当电子装置电池电量高于70%时,满足预设的第二切换条件,电子装置采用视频模式(VIDEO MODE)在中央处理器和显示设备之间传输显示数据。 When the electronic device battery capacity is above 70%, the second predetermined switching condition is satisfied, the electronic device using the video mode (VIDEO MODE) the display data transfer between the central processor and the display device. 第一电量阈值与第二电量阈值的选择这里并不限于以上所述。 Selecting a first charge threshold value and the second threshold quantity herein is not limited to the above.

[0040] 于本实施方式中,第一电量阈值与第二电量阈值的具体选择并不限于以上所述具体数值,可以根据实际情况具体设定,也可以设置接口允许用户自行设定,方便用户使用。 [0040] in the present embodiment, the first threshold quantity particular choice of a second electric quantity threshold is not limited to the above specific values, may be specifically set according to the actual situation, an interface may be provided to allow user-set, user use.

[0041] 本发明第三实施方式涉及一种显示数据的传输方法。 [0041] The third embodiment of the present invention relates to a method for transmitting display data. 第三实施方式与第一实施方式大致相同,主要区别之处在于:在第一实施方式中预设的第一切换条件和预设的第二切换条件为触发设备接收的不同的模式切换触发指令。 The third embodiment is substantially the same as the first embodiment, the main difference is that: in a first embodiment, the predetermined switching condition and the first predetermined condition is different from the second switching device triggering mode instruction received handover trigger . 而在本发明第三实施方式中,通过对判断显示数据当前帧和前一帧数据变化率在命令模式(COMMAND MODE)和视频模式(VIDEOMODE)之间进行切换,极大地降低了电子装置的功耗,并提高了电子装置的电池续航能力。 In the third embodiment of the present invention, it is determined by the display data of the current frame and a previous frame data rate change between the command mode (COMMAND MODE) and a video mode (VIDEOMODE) switch, which greatly reduces the power of the electronic apparatus consumption, and increase the battery life of the electronic device.

[0042] 以下仍然以第一模式为视频模式(VIDEO MODE),第二模式为命令模式(COMMANDMODE)为例进行说明。 [0042] The first mode is the still video mode (VIDEO MODE), the second mode is a mode command (COMMANDMODE) as an example. 对应地,预设的第一切换条件为数据变化率低于预设的第一变化阈值;预设的第二切换条件为数据变化率高于或等于预设的第二变化阈值;其中,数据变化率为显示数据当前帧和前一帧的数据变化率,第一变化阈值小于或等于第二变化阈值。 Correspondingly, a first switching condition preset lower than a preset variation threshold for the first data change rate; a second switching condition preset data is higher than or equal to a predetermined change in a second variation threshold; wherein the data rate of change in the display data of the current frame and the previous frame data change rate, the first threshold is less than or equal to the change in the second variation threshold.
