为了更好的理解本说明书的技术方案,下面结合附图对本申请实施例进行详细描述。In order to better understand the technical solution of this specification, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

在本申请实施例中使用的术语是仅仅出于描述特定实施例的目的,而非旨在限制本说明书。在本申请实施例和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式,除非上下文清楚地表示其他含义。The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit this specification. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.
随着显示技术的发展,显示方案愈发复杂,以使显示系统能够满足各种显示要求,并且用户对于显示屏上的显示效果的要求也愈高,其中,显示链路中传输的数据包的时序是确保显示屏中显示画面的显示效果的关键。With the development of display technology, display solutions have become more and more complex, so that the display system can meet various display requirements, and users have higher requirements for the display effects on the display screen. Among them, the timing of data packets transmitted in the display link is the key to ensuring the display effect of the picture displayed on the display screen.
经本申请发明人研究发现,在数据包传输的过程中,由于数据包的显示时序易受到外界干扰,导致所传输的数据包的显示时序出现错误,使的显示屏基于时序错误的数据包进行显示后的显示画面会出现错行、缺屏的情况,从而影响了显示效果。The inventors of the present application have discovered through research that, during data packet transmission, the display timing of the data packets is susceptible to external interference, resulting in errors in the display timing of the transmitted data packets. As a result, the display screen will display the screen based on the data packets with incorrect timing, with misaligned lines or missing screens, thus affecting the display effect.
鉴于此,本申请实施例提供了一种显示数据处理方法,该方法可以应用于如图1所示的电子设备中,电子设备可以包括片上系统(System on Chip,SOC)和显示装置,考虑到显示装置离片上系统SOC较远时,在显示屏上显示画面需要由片上系统SOC长距离高速传输显示数据至显示装置,因此在片上系统SOC与显示装置之间存在有显示链路,即SOC通过显示链路通信连接于显示装置。SOC可以通过显示链路将显示数据发送至显示装置。显示链路中可以设置有显示数据处理装置,显示数据处理可以具体可以为显示链路芯片,SOC也可以为其他能够产生显示装置的装置,显示 数据处理装置中可以设有数据包解码器(packet protocol structure decoder),数据包解码器具有数据包解析能力。显示装置可以是多种显示接口和多种显示接口对应的显示屏,比如移动行业处理器-串行显示接口MIPI-DSI、低电压差分信号接口LVDS、嵌入式显示端口EDP、高清多媒体接口HDMI,以及这4种接口对应的显示屏。In view of this, an embodiment of the present application provides a display data processing method, which can be applied to an electronic device as shown in FIG1 . The electronic device may include a system on chip (SOC) and a display device. Considering that when the display device is far away from the system on chip SOC, the display screen requires the system on chip SOC to transmit the display data to the display device over a long distance and at high speed. Therefore, there is a display link between the system on chip SOC and the display device, that is, the SOC is connected to the display device through the display link communication. The SOC can send the display data to the display device through the display link. A display data processing device may be provided in the display link, and the display data processing may specifically be a display link chip. The SOC may also be other devices capable of generating a display device, and the display The data processing device may be provided with a packet decoder (packet protocol structure decoder), which has the ability to parse packets. The display device may be a plurality of display interfaces and display screens corresponding to the plurality of display interfaces, such as the mobile industry processor-serial display interface MIPI-DSI, the low voltage differential signal interface LVDS, the embedded display port EDP, the high-definition multimedia interface HDMI, and the display screens corresponding to the four interfaces.
下面结合附图对本申请实施例提供的技术方案进行介绍。请参见图2,本发明实施例提供了一种显示数据处理方法,该方法可以应用于上述的显示数据处理装置,该方法流程描述如下:The technical solution provided by the embodiment of the present application is introduced below in conjunction with the accompanying drawings. Referring to FIG2 , an embodiment of the present invention provides a display data processing method, which can be applied to the above-mentioned display data processing device. The method flow is described as follows:
步骤101、获取显示数据;Step 101, obtaining display data;
例如,接收SOC生成并发送的显示数据,显示数据例如为显示串行接口(Display Serial Interface,DSI)数据。如图3所示,以一种DSI数据的结构为例具体进行说明,图3示意了DSI数据中的数据包之间的时序。其中,垂直同步开始(Vertical Sync Start,VSS)数据包表示一帧数据场同步,水平同步开始(Horizontal Sync Start,HSS)数据包表示行同步开始,水平同步结束(Horizontal Sync End,HSE)数据包表示行同步结束。水平同步活动(Horizontal Sync Active,HSA)数据包、水平后肩(Horizontal Back Porch,HBP)数据包和水平前肩(Horizontal Front Porch,HFP)数据包所显示的行周期是由空白数据包填充的,其长度(包括数据包开销)计算出来,以匹配外设数据指定的周期。垂直同步活动(Horizontal Sync Active,VSA)数据包、垂直后肩(Horizontal Back Porch,VBP)数据包和垂直前肩(Vertical Front Porch,VFP)数据包所显示的场周期由HSS数据包、HSA数据包、HSE数据包、消隐或低功耗间隔(Blanking or Low Power Interval,BLLP)数据包和空白数据包组成的空白行填充,有效显示数据由每帧有效扫描行(Active lines per frame,VACT)数据传输。所以,对于整个显示链路,每个链路正确解析DSI同步周期包、时序(HBP、HFP、HSA、VBP、VFP、VSA)、显示数据是确保显示正常的根本所在。For example, display data generated and sent by the SOC is received, and the display data is, for example, display serial interface (DSI) data. As shown in FIG3, a structure of DSI data is used as an example for specific description, and FIG3 illustrates the timing between data packets in the DSI data. Among them, the vertical sync start (Vertical Sync Start, VSS) data packet represents a frame of data field synchronization, the horizontal sync start (Horizontal Sync Start, HSS) data packet represents the start of line synchronization, and the horizontal sync end (Horizontal Sync End, HSE) data packet represents the end of line synchronization. The line cycle displayed by the horizontal sync active (Horizontal Sync Active, HSA) data packet, the horizontal back porch (Horizontal Back Porch, HBP) data packet and the horizontal front porch (Horizontal Front Porch, HFP) data packet is filled with blank data packets, and its length (including data packet overhead) is calculated to match the cycle specified by the peripheral data. The field period displayed by the vertical sync active (VSA) data packet, the vertical back porch (VBP) data packet and the vertical front porch (VFP) data packet is filled with blank lines composed of HSS data packets, HSA data packets, HSE data packets, blanking or low power interval (BLLP) data packets and blank data packets, and the effective display data is transmitted by the active lines per frame (VACT) data. Therefore, for the entire display link, the correct parsing of the DSI synchronization cycle packet, timing (HBP, HFP, HSA, VBP, VFP, VSA), and display data by each link is the fundamental to ensure normal display.
步骤102、将显示数据中的多个数据包解析为显示像素接口(Display Pixel Interface,DPI)信号。Step 102, parse multiple data packets in the display data into display pixel interface (DPI) signals.
其中,步骤102中的多个数据包为显示数据中的至少部分数据包。如图4所示,DPI信号与显示数据中的数据包对应,显示数据中的数据是封装后的数据包形式,在步骤102中,将其中的多个数据包进行解析,解析为DPI信号,DPI信号具有具体的信号波形。The multiple data packets in step 102 are at least part of the data packets in the display data. As shown in FIG4 , the DPI signal corresponds to the data packets in the display data, and the data in the display data is in the form of encapsulated data packets. In step 102, the multiple data packets are parsed into DPI signals, and the DPI signals have specific signal waveforms.
步骤103、确定DPI信号的时序与预设时序是否一致,若是,即若DPI信号的时序与预设时序一致,则执行步骤104、发送显示数据至显示装置,若否,即若DPI信号的时序与预设时序不一致,则执行步骤105;Step 103, determining whether the timing of the DPI signal is consistent with the preset timing, if yes, that is, if the timing of the DPI signal is consistent with the preset timing, executing step 104, sending the display data to the display device, if no, that is, if the timing of the DPI signal is inconsistent with the preset timing, executing step 105;
步骤105、对多个数据包进行修正,使修正后的多个数据包解析得到的DPI信号的时序与预设时序一致,并执行步骤106、发送包括修正后的多个数据包的显示数据至显示装置。Step 105 , correcting the multiple data packets so that the timing of the DPI signal obtained by parsing the corrected multiple data packets is consistent with the preset timing, and executing step 106 , sending the display data including the corrected multiple data packets to the display device.
具体地,根据图3和图4所示可知,正确的显示数据中多个数据包的时序是固定的,所以说,正确的多个数据包在解析为DPI信号后,其中对应信号的时序也是固定的,固定的DPI信号时序即为预设时序,如果当前的显示数据没有被干扰而改变数据 包的顺序,那么,解析后的DPI信号的时序应该与预设时序一致,所以说,如果在步骤103中判断DPI信号的时序与预设时序一致,则说明显示数据没有被干扰,是正确的显示数据,因此可以将正确的显示数据发送至显示设备。而如果当前的显示数据被外界干扰导致数据包的顺序异常,那么,解析后的DPI信号的时序会发生变化,即与预设时序不一致,此时则说明显示数据异常,因此,执行步骤105,对显示数据进行修正,之后发送修正后的显示数据至显示装置,以使显示装置可以正常显示。Specifically, as shown in FIG. 3 and FIG. 4, the timing of multiple data packets in the correct display data is fixed. Therefore, after the correct multiple data packets are parsed into DPI signals, the timing of the corresponding signals is also fixed. The fixed DPI signal timing is the preset timing. If the current display data is not disturbed and the data is changed, If the sequence of the packets is different, then the timing of the DPI signal after parsing should be consistent with the preset timing. Therefore, if it is determined in step 103 that the timing of the DPI signal is consistent with the preset timing, it means that the display data is not interfered with and is correct display data, so the correct display data can be sent to the display device. If the current display data is interfered with by the outside world and the sequence of the data packets is abnormal, then the timing of the DPI signal after parsing will change, that is, it is inconsistent with the preset timing, which means that the display data is abnormal. Therefore, step 105 is executed to correct the display data, and then the corrected display data is sent to the display device so that the display device can display normally.
本申请实施例中的显示数据处理方法,将显示数据中的多个数据包解析为DPI信号,再基于DPI信号的时序确定显示数据是否异常,如果异常,则对显示数据进行修正,即可以修正显示链路中显示数据的显示时序,从而改善显示链路由于干扰而导致的显示异常。The display data processing method in the embodiment of the present application parses multiple data packets in the display data into DPI signals, and then determines whether the display data is abnormal based on the timing of the DPI signal. If abnormal, the display data is corrected, that is, the display timing of the display data in the display link can be corrected, thereby improving the display abnormality caused by interference in the display link.
在一些实施例中,显示数据包括控制时序数据包和显示数据包,上述多个数据包为显示数据中的控制时序数据包。In some embodiments, the display data includes a control timing data packet and a display data packet, and the plurality of data packets are the control timing data packets in the display data.
具体地,控制时序数据包用于实现显示控制或传输控制,显示数据包用于实现画面的显示。控制时序数据包容易受到外界干扰而变化,因此,可以仅对显示数据中的控制时序数据包进行解析和修正,无需对显示数据包进行解析,以提高数据处理和传输速度。Specifically, the control timing data packet is used to implement display control or transmission control, and the display data packet is used to implement the display of the picture. The control timing data packet is easily changed by external interference, so only the control timing data packet in the display data can be parsed and corrected, without parsing the display data packet, so as to improve the data processing and transmission speed.
在一些实施例中,控制时序数据包包括水平后肩HBP数据包、水平前肩HFP数据包、水平同步活动HSA数据包、垂直后肩VBP数据包、垂直前肩VFP数据包和垂直同步宽带VSA数据包,其中水平后肩HBP数据包、水平前肩HFP数据包以及水平同步有效HSA数据包表示行周期,垂直后肩VBP数据包、垂直前肩VFP数据包以及垂直同步活动VSA数据包表示场周期,将显示数据中的控制时序数据包解析为DPI信号则是将上述的各种控制时序数据包解析为DPI信号。In some embodiments, the control timing data packets include horizontal back shoulder HBP data packets, horizontal front shoulder HFP data packets, horizontal synchronization active HSA data packets, vertical back shoulder VBP data packets, vertical front shoulder VFP data packets and vertical synchronization wideband VSA data packets, wherein the horizontal back shoulder HBP data packets, horizontal front shoulder HFP data packets and horizontal synchronization valid HSA data packets represent line cycles, the vertical back shoulder VBP data packets, vertical front shoulder VFP data packets and vertical synchronization active VSA data packets represent field cycles, and parsing the control timing data packets in the display data into DPI signals means parsing the above-mentioned various control timing data packets into DPI signals.
在一些实施例中,DPI信号包括垂直同步VSYNC信号和水平同步HSYNC信号,其中,垂直同步VSYNC信号表示每一帧画面对应的DPI信号,水平同步HSYNC信号表示每帧画面中一行对应的DPI信号,将显示数据中的控制时序数据包解析为DPI信号则是将控制时序数据包解析为垂直同步VSYNC信号和水平同步HSYNC信号。In some embodiments, the DPI signal includes a vertical synchronization VSYNC signal and a horizontal synchronization HSYNC signal, wherein the vertical synchronization VSYNC signal represents the DPI signal corresponding to each frame of the picture, and the horizontal synchronization HSYNC signal represents the DPI signal corresponding to a line in each frame of the picture, and parsing the control timing data packet in the display data into the DPI signal is to parse the control timing data packet into a vertical synchronization VSYNC signal and a horizontal synchronization HSYNC signal.
具体地,例如在图4中,每帧中,显示区域对应的信号位于VBP对应的信号和VFP对应的信号之间;每行中,显示数据区域对应的信号位于HBP对应的信号和HFP之间。VSYNC信号包含对应VBP的部分和对应VFP的部分,HSYNC信号包含了对应HBP的部分和对应HFP的部分。对于正确的显示数据,在每帧中,控制时序对应的信号,例如VSYNC信号位于显示区域之外的部分的高低电平时序都是固定相同的;在每行中,控制时序对应的信号,例如HSYNC信号位于显示数据区域之外的部分的高低电平时序都是固定相同的。因此,可以根据上述信号来确定DPI信号的时序是否与预设时序一致。另外,对应异常的显示数据,根据DPI信号中高低电平时序,可以具体确定某一段DPI信号所对应的数据包,基于预设时序,即可以确定数据包具体发生了什么样的顺序错乱,从而可以对显示数据中的数据包的顺序进行调整,以实现数据包的修正。Specifically, for example, in FIG. 4 , in each frame, the signal corresponding to the display area is located between the signal corresponding to VBP and the signal corresponding to VFP; in each row, the signal corresponding to the display data area is located between the signal corresponding to HBP and HFP. The VSYNC signal includes a portion corresponding to VBP and a portion corresponding to VFP, and the HSYNC signal includes a portion corresponding to HBP and a portion corresponding to HFP. For correct display data, in each frame, the high and low level timings of the signal corresponding to the control timing, such as the portion of the VSYNC signal located outside the display area, are fixed and the same; in each row, the high and low level timings of the signal corresponding to the control timing, such as the portion of the HSYNC signal located outside the display data area, are fixed and the same. Therefore, it is possible to determine whether the timing of the DPI signal is consistent with the preset timing based on the above signal. In addition, corresponding to abnormal display data, according to the high and low level timings in the DPI signal, the data packet corresponding to a certain section of the DPI signal can be specifically determined, and based on the preset timing, it is possible to determine what kind of order disorder has occurred in the data packet, so that the order of the data packets in the display data can be adjusted to achieve the correction of the data packet.
在一些实施例中,DPI信号包括显示数据信号中的无效显示信号。 In some embodiments, the DPI signal includes an invalid display signal in the display data signal.
具体地,例如,在图4中,DB为显示数据信号,其中0、1、2、3、…、n为有效显示信号,0~n之外的部分为无效显示信号,有效显示信号可以用于表征显示像素的灰阶值,实现显示功能,无效显示信号原本并无实际作用,而在本申请实施例中,可以将原本无实际作用的无效显示信号复用为对显示数据中的数据包进行标识,以便于可以基于无效显示信号来确定DPI信号的时序与预设时序是否一致,即确定显示数据中的多个数据包的顺序是否异常,以及在多个数据包的顺序异常时,可以根据无效显示信号的标识来对显示数据中的数据包顺序进行修正。Specifically, for example, in Figure 4, DB is a display data signal, wherein 0, 1, 2, 3, ..., n are valid display signals, and the parts other than 0 to n are invalid display signals. The valid display signal can be used to characterize the grayscale value of the display pixel and realize the display function. The invalid display signal originally has no practical effect. In an embodiment of the present application, the invalid display signal that originally has no practical effect can be multiplexed to identify the data packets in the display data, so that it is possible to determine whether the timing of the DPI signal is consistent with the preset timing based on the invalid display signal, that is, to determine whether the order of multiple data packets in the display data is abnormal, and when the order of multiple data packets is abnormal, the order of the data packets in the display data can be corrected according to the identification of the invalid display signal.
在一些实施例中,如图5所示,显示链路中的数据包解码器可以将DSI数据中的多个数据包解析为VSYNC信号、HSYNC信号、DB信号和数据使能(Data Enable,DE)信号。In some embodiments, as shown in FIG. 5 , a packet decoder in a display link may parse multiple packets in the DSI data into a VSYNC signal, an HSYNC signal, a DB signal, and a data enable (DE) signal.
在一些实施例中,请参见图6,显示链路可以为串联的n条链路,其中n为大于1的整数,显示数据包括n条显示链路中的显示数据,要保证显示屏能够基于最终接收到的多个数据包显示正确的画面,就需要整体显示链路发送至显示装置的多个数据包的时序是正确的。In some embodiments, referring to FIG. 6 , the display link may be n links connected in series, where n is an integer greater than 1, and the display data includes the display data in the n display links. To ensure that the display screen can display the correct picture based on the multiple data packets finally received, the timing of the multiple data packets sent from the entire display link to the display device must be correct.
作为一种可能的实施方式,当片上系统SOC与显示装置之间的显示链路为n条时,可以在每条显示链路中都设有数据包解码器,便基于n条显示链路依次将显示数据中的多个数据包解析为DPI信号,即每条显示链路中的数据包解码器都会对接收到的显示数据中的多个数据包进行解析,得到DPI信号,确定DPI信号的时序与预设的时序是否一致,若一致,则基于该显示链路发送多个数据包至下一个显示链路,若不一致,对多个数据包进行修正后再发送多个数据包至下一个显示链路,以使显示屏能够基于最终接收到的多个数据包显示正确的画面。As a possible implementation, when there are n display links between the system on chip SOC and the display device, a data packet decoder can be provided in each display link, and multiple data packets in the display data are sequentially parsed into DPI signals based on the n display links, that is, the data packet decoder in each display link will parse the multiple data packets in the received display data to obtain the DPI signal, and determine whether the timing of the DPI signal is consistent with the preset timing. If they are consistent, multiple data packets are sent to the next display link based on the display link. If they are inconsistent, the multiple data packets are corrected and then sent to the next display link, so that the display screen can display the correct picture based on the multiple data packets finally received.
例如,当显示链路1接收到显示数据中的多个数据包时,显示链路1中的数据包解码器会对该显示数据中的多个数据包进行解析,得到DPI信号,确定DPI信号的时序与预设的时序是否一致,若一致,则基于该显示链路发送多个数据包至显示链路2,若不一致,对多个数据包进行修正后再发送多个数据包至显示链路2,直到显示链路n中的数据包解码器对显示数据中的多个数据包进行解析,得到DPI信号,确定DPI信号的时序与预设的时序是否一致,若一致,则基于该显示链路发送多个数据包至显示装置,若不一致,对多个数据包进行修正后再发送多个数据包至显示装置。For example, when display link 1 receives multiple data packets in display data, the data packet decoder in display link 1 will parse the multiple data packets in the display data to obtain a DPI signal, and determine whether the timing of the DPI signal is consistent with the preset timing. If they are consistent, the multiple data packets are sent to display link 2 based on the display link. If they are inconsistent, the multiple data packets are corrected and then sent to display link 2, until the data packet decoder in display link n parses the multiple data packets in the display data to obtain a DPI signal, and determines whether the timing of the DPI signal is consistent with the preset timing. If they are consistent, the multiple data packets are sent to the display device based on the display link. If they are inconsistent, the multiple data packets are corrected and then sent to the display device.
