Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The application discloses a processing method and a display device, aiming at the problem of incompatibility between the display device and the processing device, the image display effect of the display device is improved, and the image display quality of the display device is improved. The processing method disclosed in the embodiment of the present application is applied to a Display device, and the Display device may be, but not limited to, an LCD (Liquid Crystal Display), an LED (Light-Emitting Diode), or an OLED (Organic Light-Emitting Diode) Display.
Referring to a flow chart of the processing method provided in fig. 2, the processing method disclosed in the embodiment of the present application includes:
The display device is referred to the above description, and is the main body of the application.
The processing device may be, but is not limited to, a host computer of a personal computer, a server computer, or a device having a display information processing function and composed of multiple processors and related peripheral circuits. The Processing device includes a display Processing component, which may be, but is not limited to, an Integrated Graphics Processing Unit (iGPU) or a discrete Graphics Processing Unit (dGPU).
Specifically, when the display device is connected to the processing device, such as when a certain display is connected to the host computer, the display device detects a connection signal, and obtains attribute data transmitted by the processing device in response to the detected connection signal.
The applicant has found that when the mismatch between the display device and the processing device affects the picture display effect of the display device, mainly due to the incompatibility of the display interface (DP) transmission protocol version of the display device and the transmission protocol version of the display interface of the processing device, for example, the DP version of the display is higher than the DP version of the host graphics card, which makes the host graphics card unable to support, and based on this, when the display device is connected with the processing device for information display, the display device responds to the detected connection signal, the obtained attribute data transmitted by the processing device at least comprises processing end protocol version information, the processing end protocol version information is used for indicating the transmission protocol version of the display interface in the processing device, such as DP1.2, etc., besides, the attribute data may also include, but is not limited to, other graphics card parameters such as video memory frequency, bit width, etc., without limitation.
When the target identification data is generated according to the attribute data transmitted by the processing device, the display device specifically judges whether the processing end protocol version information and the original version information of the display interface transmission protocol in the display device meet the preset version condition, and if not, generates second identification data matched with the processing end protocol version information as the target identification data. And if the first identification data is satisfied, generating third identification data matched with the original version information of the display interface transmission protocol in the display device as target identification data.
The version condition is a condition that can be used to characterize that the version of the transmission protocol of the display interface in the processing device is compatible with the original version of the transmission protocol of the display interface in the display device, and optionally, the version condition may be specifically set as: the transmission protocol version of the display interface in the processing device is the same as the original transmission protocol version of the display interface in the display device, or the transmission protocol version of the display interface in the processing device is not lower than the original transmission protocol version of the display interface in the display device.
The original version information of the transmission protocol of the display interface in the display device is the actual version information of the transmission protocol of the display interface of the display device.
The target identification data comprises display parameters of a display device, and the display parameters at least comprise resolution. And under the condition that the version information of the processing end protocol and the original version information of the transmission protocol of the display interface in the display device meet the version condition, the resolution included in the display parameter is the optimal resolution matched with the original version information of the transmission protocol of the display interface in the display device, and under the condition that the version condition is not met, the resolution included in the display parameter is the optimal resolution matched with the version information of the processing end protocol.
The optimal resolution matched with the original version information of the transmission protocol of the display interface in the display device is the maximum resolution supported by the display device; and the best resolution matched with the protocol version information of the processing end is the maximum resolution which can be supported by the processing device.
And then, the display device transmits the target identification data to the processing device, so that the processing device can output the display signals according to the optimal resolution matched with the actual versions of the display interfaces of the display end under the condition that the versions of the display interfaces at the two ends of the display end and the processing end are compatible, and the processing device can output the display signals according to the optimal resolution matched with the versions of the display interfaces of the processing device under the condition that the versions of the display interfaces at the two ends of the display end and the processing end are incompatible.
For example, assuming that the DP version of the host-side display card is DP1.2, if the DP version of the display is not higher than DP1.2, such as DP1.1, the two are compatible, the host-side display card outputs the display signal according to the optimal resolution corresponding to DP1.1, if the DP version of the display is higher than DP1.2, such as DP1.4, the two are incompatible, and the host-side display card outputs the display signal according to the optimal resolution corresponding to DP1.2, so that under the condition that the versions of the display interface of the display side and the processing side are incompatible, the display signal can be output according to the optimal resolution supported by the processing side and displayed on the display device, and the display device can have a better image display effect as much as possible.
The target identification data may be, but not limited to, in a data format of EDID (Extended display identification data).
As apparent from the above, the method of the present embodiment enables the processing device to output a display signal matching the display parameter by obtaining, at the display device, the attribute data transmitted by the processing device, generating, from the attribute data transmitted by the processing device, target identification data for the processing device to determine the display parameter of the connected display device, and transmitting, to the processing device, the target identification data including the display parameter. Because the target identification data of the display device is generated according to the attribute data transmitted by the processing device, and the display signal matched with the display parameter in the target identification data is output by the processing device, the display device can be effectively identified and supported by the processing device, and the adverse effect on the picture display effect caused by the problems of identification and support of the display device by the processing device can be correspondingly avoided, so that the display device has a better picture display effect as far as possible, and the aim of improving the picture display effect under the condition that the display device is incompatible with the processing device is fulfilled.
In one embodiment, the processing method of the present application, through two communication processes, namely a first communication process and a second communication process, based on EDID between a display device and a processing device, realizes an improvement of a screen display effect of the display device in a case where an actual version of a display interface of the display device is incompatible with a version of the display interface of the processing device, wherein:
the display device obtains at least the attribute data transmitted from the processing device by performing a first communication process with the processing device, and transmits at least target identification data including the display parameter to the processing device by performing a second communication process with the processing device.
Referring to the flowchart of the processing method provided in fig. 3, the processing method disclosed in the present application can be further implemented by the above-mentioned EDID-based two-time communication processing:
The connection signal when the display device is connected to the processing device may be, but is not limited to, a hot plug signal generated when the display device is connected to the processing device by a hot plug method.
In conjunction with the two EDID interaction flows shown in fig. 4, in step (i), when the user accesses the display device to the processing device through a hot plug operation, the level of the hot plug pin of the connection interface of the display device (the connection interface with the processing device) changes, such as being pulled high, and the high level signal can be used as a connection signal when the display device is connected to the processing device.
When detecting a connection signal when the display device is connected to the processing device, the display device performs a connection initialization process with the processing device, specifically, Link tracing in step two of fig. 1.
In the connection initialization process, the display device sends first initialization parameter information to the processing device, see step c executed in the Link tracing process of step c in fig. 1, where the first initialization parameter information includes original version information (for example, DP1.4 in step c) of a transmission protocol of a display interface in the display device and first operating parameters matched with the original version information, where the first operating parameters include, but are not limited to, information such as voltage, voltage swing, frequency, and number of channels matched with the original version information, and are intended to cause the processing device to generate and output a display signal based on the first operating parameters matched with the original version information.
In addition, during the connection initialization process, the display device also receives attribute data output by the processing device, where the attribute data at least includes version information of the display interface of the processing device, and refer to step iv in fig. 1, where the display interface version DP1.2 of the display card in the host computer is received by the display.
After the connection initialization is completed, the display apparatus sends the EDID information corresponding to the original version (actual version) of the display interface transport protocol thereof, i.e. the first identification data to the processing apparatus, which may be referred to in conjunction with step (v) of fig. 4, where the first identification data includes the display parameters matched with the original version information, where the display parameters at least include the resolution. The resolution in the first identification data is the best resolution matching the original version (actual version) information of the transport protocol of the display interface in the display device, such as the resolution matching DP1.4, typically the maximum resolution supported by the display device.
Step 301-.
The display device obtains the transmission protocol version (for example, DP1.2) of the display interface of the processing device through the first communication processing procedure, and informs the processing device of the actual version information of the transmission protocol of the display interface of the display device itself and the matched information of the display parameter, the working parameter (first working parameter), and the like.
After the processing device (such as a computer host) receives the information of the actual version of the display interface transmission protocol of the display device and the matched display parameters, working parameters and the like, if the actual version of the display interface transmission protocol of the display device is higher than the version of the display interface transmission protocol in the processing device, and if the display interface version DP1.4 of the display device is higher than the host display interface version DP1.2, a display processing part in the processing device such as a display card cannot support the output of display signals according to the actual version of the display interface transmission protocol of the display device, and otherwise, the display processing part can support the output of display signals according to the actual version of the display interface transmission protocol of the display device.
And step 304, if the version information of the processing end protocol and the original version information do not meet the version condition, generating second identification data matched with the version information of the processing end protocol.
After the display device obtains the transmission protocol version of the display interface of the processing device through the first communication processing process, the transmission protocol version of the display interface in the processing device is compared with the original version of the transmission protocol of the display interface of the display device, whether the transmission protocol version of the display interface in the processing device and the original version of the transmission protocol of the display interface of the display device meet the version condition or not is judged, whether the transmission protocol version of the display interface of the display device is higher than the transmission protocol version of the display interface in the processing device or not is judged, if the transmission protocol version of the display interface of the display device is higher than the transmission protocol version of the display interface in the processing device or not, the version condition is not met, otherwise, the version condition is met, and the compatibility of the transmission protocol version and the display interface is represented.
If the transmission protocol version of the display interface in the processing device and the original version of the display interface transmission protocol of the display device do not meet the version condition, second identification data matched with the processing end protocol version information is generated, for example, EDID data matched with the display interface version DP1.2 of the computer host side display card is generated. If the version condition is satisfied, it is preferable that the present embodiment does not generate and transmit the target identification data to the processing device, and the processing device directly performs identification and display signal output on the display device based on the original version of the display interface transmission protocol in the display device obtained in the first communication processing procedure (that is, the version of the display interface transmission protocol at the processing device end).
In this embodiment, an identification data set is pre-established and stored in the display device, different identification data in the identification data set respectively correspond to different versions of a transmission protocol of the display interface, and each identification data can be used for identifying the display device and at least includes a display parameter matched with the corresponding version of the transmission protocol.
The different identification data in the identification data set may be respectively different EDID data corresponding to different versions (i.e. different DP versions) of the display interface transmission protocol in the display device, where the different DP versions corresponding to the different EDID data respectively include an original version (actual version) of the display interface transmission protocol in the display device and various versions lower than the original version of the display interface transmission protocol in the display device, for example, assuming that the original version of the display interface transmission protocol in the display device is DP1.4, the different DP versions corresponding to the different EDID data in the identification data set may be a series of versions DP1.4, DP1.2, DP1.1, DP1.0, etc., and the different DP versions match different display parameters, such as match different optimal resolutions, etc., where the optimal resolution corresponding to the DP protocol of the lower version is correspondingly lower.
Preferably, in this embodiment, at least two storage units are provided in the display device in advance: a first storage section and a second storage section. The first storage means is for storing the above-mentioned identification data set, e.g., storing different EDID data corresponding to DP1.4, DP1.2, DP1.1, DP1.0, respectively; the second storage section is used to store identification data currently employed by the display apparatus, for example, EDID data corresponding to DP 1.4.
Optionally, the first storage component is a Read-Only Memory (ROM), and the second storage component is a Random Access Memory (RAM).
In this step 304, if the version of the transmission protocol of the display interface in the processing apparatus and the original version of the transmission protocol of the display interface of the display apparatus do not satisfy the version condition, the identification data matched with the version information of the processing end protocol may be specifically determined and selected from the first storage component as the second identification data, so as to generate the second identification data matched with the version information of the processing end protocol, and the second identification data is updated to the second storage component, so that the display apparatus interacts with the processing apparatus using the second identification data.
For example, for the case that the DP version DP1.4 of the display is higher than the DP version DP1.2 of the host display card, specifically, the EDID data matching the DP1.2 is selected from the first storage unit, and the EDID data matching the DP1.2 is written into the second storage unit, referring to fig. 4 in combination, the actual version DP1.4 of the display interface of the display is loaded to the second storage unit through the step of:' in advance in fig. 4, and when the display is connected to the host computer, through the above processing procedure, the EDID data matching the DP1.2 of the host display card is selected from the first storage unit, and the EDID data matching the DP1.2 is updated to the second storage unit through the step of:.
Referring to step (c) of fig. 4, specifically, by generating a connection signal when the display device is connected to the processing device, such that a process of re-initializing the connection between the display device and the processing device is triggered based on the connection signal, the re-executed connection initialization specifically refers to Link tracking of step (b) of fig. 4.
In an implementation, a hot plug operation when the display device is switched into the processing device may be simulated by generating a hot plug signal (e.g., the above high level signal) when the display device is switched into the processing device, so as to trigger a process of reinitializing connection between the display device and the processing device.
Referring to step ninthly in fig. 4, in the process of performing connection initialization again, second initialization parameter information is sent to the processing apparatus, where the second initialization parameter information includes processing end protocol version information and second operating parameters matched with the processing end protocol version information, and taking the processing end protocol version information as DP1.2 as an example, the second initialization parameter information specifically includes DP1.2 and operating parameter information such as voltage, voltage swing, frequency, channel number and the like matched with DP 1.2.
In addition, in the course of re-initialization of connection, the processing side protocol version information outputted from the processing apparatus is also received, as in fig. 4, DP version information DP1.2 transmitted from the host computer is received in step r.
Thereafter, after the re-performed connection initialization is completed, the secondary EDID data, i.e., the second identification data, continues to be transmitted to the processing device, as in the step of fig. 4
The second identification data comprises at least display parameters matching the protocol version information of the processing end, such as the best resolution matching DP 1.2.
Step 305-307 is a processing procedure of the second communication process based on the EDID.
In the case that the transmission protocol version of the display interface of the display device is incompatible with the transmission protocol version of the display interface of the processing device, the processing device can obtain the display parameters (such as the optimal resolution matched with the DP1.2) and the related working parameters which are transmitted by the display device and matched with the protocol version information of the display interface of the processing device through the processing process of the second communication processing.
Subsequently, the processing device will generate and output the display signal based on the display parameter (e.g. the best resolution matching with DP1.2) and the related operating parameter (the second operating parameter) matching with the version information of the processing device's own display interface protocol, as shown in the step of fig. 4
The display device can correspondingly receive the display signal generated and output by the processing device based on the display parameter and the relevant working parameter corresponding to the protocol version information of the processing device through the display interface, and display the display signal.
In implementation, when the connection between the display apparatus and the processing apparatus is disconnected, such as by a hot plug operation, it is preferable that the display apparatus restores the identification data in the second storage part to the identification data corresponding to its original version information (actual version information), such as the EDID data corresponding to DP1.4, in response to the detected connection interruption signal, so as to perform the related processing with the connected processing apparatus based on its original version information when connected with the other processing apparatus.
In this embodiment, through the above two communication processes based on the EDID, on the premise that the transmission protocol version of the display interface of the display device is incompatible with the transmission protocol version of the display interface of the processing device, the display device can adaptively interact with the processing device based on the identification data matched with the protocol version of the processing terminal on the premise that the existing identification process of the display based on the EDID is changed as little as possible, so that the display device can be effectively identified and supported by the processing device, and the display signal can be output to the display device with the maximum resolution supported by the processing device (i.e., the optimal resolution corresponding to the protocol version of the processing terminal), so that the display signal of the display device can have a better resolution as far as possible, and the display effect of the display device can be improved.
Referring to the flowchart of the processing method provided in fig. 5, for the processing flow corresponding to fig. 2, if the processing-side protocol version information is not compatible with the original version information of the display interface transmission protocol of the display device, the processing method disclosed in this application, after step 503, may further include:
After the display device sends the first initialization parameter information and the first identification data to the processing device through the first communication process, for example, after sending the DP version DP1.4 of the display and the display parameters such as the related working parameters and the resolution that match the DP1.4 to the host computer, because the processing device does not support the higher version of the display interface, the output of the display signal is usually performed based on the random display parameters and the working parameters, which also causes the problems that the resolution of the image is extremely poor or the black screen cannot be displayed on the display device side.
In view of this situation, in this embodiment, after the display device sends the first initialization parameter information and the first identification data to the processing device through the first communication process, the display device receives, through the display interface, a display signal Output by the processing device according to the first initialization parameter information and the first identification data, and performs a masking process on the display signal, see Output video data indicated by a dashed arrow in fig. 6, that is, the masking process on the display signal is shown.
By shielding the display signal output by the processing device, the problems that the picture display effect is poor or the black screen cannot be displayed and the like in the display device in the first communication processing stage are effectively avoided, and accordingly poor user experience can be avoided.
The embodiment of the application also discloses a display device which can be but is not limited to an LCD, an LED or an OLED display. The composition structure of the display device is shown in fig. 6, and specifically includes:
a display screen 601;
a display interface 602, configured to receive a display signal output by the processing apparatus to drive a display screen to display information;
a controller 603 configured to perform at least the following:
