Description

Display capability recognition generator with data editing function

The present invention relates to a display capability recognizing device, and more particularly to a display capability recognizing generator having an editing function.

According to the display, the signal transmission between the display card and the display of the host computer includes two types of signals: display data and display display identification data (EDID), wherein the display data is used to display the corresponding display on the display. The display and the capability identification data are built in a data connection device of the display. When the display is connected to the display card, the data connection device triggers the display card to actively read the display capability identification data, and the display device can support the display. The resolution and the refresh rate are further selected by the user, and the display card is configured to output the display data according to the selected resolution and update rate.

In general, the higher the resolution and update rate, the higher the precision of the display screen and the finer the motion. However, the resolution and update rate are not selected by the user, but must be considered simultaneously. The specification of the display card, in general, the display is set to the complex array resolution and update rate for the display card output corresponding to one of the resolution and update rate, so that the smooth display card outputs the display data to the display for playback; therefore, If the resolution and update rate are not built in the display, the corresponding display data cannot be played by the display card selection, thus limiting the resolution and update rate of the display screen, and the user is not easy to select the matching display and the display card. The best resolution of the specification, even more serious, even the specific display and display card are not at all Compatible issues.

In order to solve the above problems, a display capability recognizing device has been proposed. As shown in FIG. 6 and FIG. 7, it includes: a first port 80 for connecting to an external display card 200; The connection port 90 is connected to the external display 210; a display capability identification module 100 is connected to the first port 80 and the second port 90, and has a display card trigger end 101, and A set of display capability identification data and a display card trigger signal are generated. When detecting that the first connection port 80 has connected the display card, the display card triggering end 101 is actively outputting the display card trigger signal, so that the display card receives the display card. After the trigger signal, the set of display capability identification data is read through the first port 80.

It can be seen that the display capability identification device has little difference from the data connection device of the existing display, and is still pre-built with a set of display capability identification data, and actively requests the display card 200 to read, the main difference is that the user It can be installed between any display and display card to provide more display capability identification data, and its manufacturers will try to set the standards set by the Video Electronics Standards Association (VESA) as much as possible. The display capability identification data is built therein, and after the user connects the display capability identification device between the display card and the display, the display card reads the set of display capability identification data in the display capability identification device, that is, the user sets the display screen. There are more options for resolution and update rate to eliminate compatibility issues as much as possible, and have the opportunity to overclock the display. For example, a display with the highest resolution of 1600×900 will be hardware-based. The process is different, and may support a resolution of more than 1920×1080 (the amplitude can be exceeded for each display) Different), but in a In the normal use condition, the display does not have a built-in resolution higher than 1600×900, so the display card cannot output the display capability identification data higher than 1600×900 at all, and the display is displayed after the display capability identification device is installed. The capability identification data may include a resolution higher than 1920×1080 (or 1920×1200). If the user chooses to set the display card to output the display information according to the resolution higher than 1920×1080, and finds that the display still works normally, then Indicates that this display can actually support this resolution and overclocking the display.

However, the display capability identification data in the above display capability identification device is still established according to the standards established by VESA, and the resolution and update rate of the non-VESA standard are still not used by the user to try, although some manufacturers provide display capability. The identification device sends back the original service to write the new display capability identification data. Although this service helps the compatibility to be further improved, it is still quite inconvenient for the user, and the user who is not in the professional field of the display is incompetent. Evaluating the space that the display can overclock, so the above services do not have any substantial help for overclocking functions.

In addition, since the existing display device is further divided into an analog input type and a digital input type according to the receivable display data, the display capability identifying device is usually also provided with a switch 110, which is connected by the display capability identification module 100. The display switch identification module 100 includes a digital chip 101 and an analog wafer 102. The first and second ports 80, 90 are switched by the switch 110 to be connected to the digital wafer 101 or the analog wafer 102. The digital chip 101 and the analog wafer 102 respectively provide display capability identification data in analog input and digital input formats. However, as described above, the manufacturer provides a function of writing new display capability identification data, and the above number is crystal. Both the chip and the analog chip must use a chip with a firmware function, and these chips and the display card directly transmit signals are susceptible to specification compatibility, and often the display card cannot read the display capability recognition device, and therefore, based on In the above various problems, the existing display capability recognizing device must be improved.

In view of the above technical limitations of the display capability recognition device in combination with the effect of overclocking and its poor compatibility, the main object of the present invention is to provide a display capability recognition generator with an editing function.

The main technical means for achieving the above purpose is that the display capability recognition generator with the editing function includes: a first connection port for connecting a display card; and a second connection port for connecting a a first storage unit is configured to store the set display capability identification data; a data control module is connected to the first port and the first storage unit, and has a display connected to the first port The card trigger terminal has a display card trigger signal; a display capability identification data compiling module is connected to the data control module and the second port; an operation interface, and the display capability identification data compiling module The display capability identification data compiling module compiles and generates a corresponding display capability identification data according to the operation of the operation interface, and outputs the display capability identification data to the data control module after the compilation is completed, After receiving the display capability identification data, the data control module writes the display capability identification data into the first storage unit, and the display capability Identification data compiled mode After detecting that the data control module has completed writing the display capability identification data, the data control module outputs the display card trigger signal and provides the display capability identification data stored in the first storage unit to the external display card. take.

The display capability recognition generator can edit the display capability identification data by the user through the operation interface. In addition to exempting the program from being sent back to the original factory for updating the data, the user can also edit the resolution and update rate of various non-VESA standards by himself. Try the highest resolution and update rate that the monitor can support. In this way, even if the user is unfamiliar with the hardware characteristics of the display of each brand, the best resolution and update rate can be set by self-editing. It is also possible to edit the display capability identification data according to individual needs. For example, when the user wants to display the slide film on the display, display the dynamic photo album, and the like, the movie media can be adjusted as high as possible, and the resolution adjustment is updated. Rate (media with no exquisite motion, no need for too high update rate); when displaying action type movies or 3D online games (requires high update rate), you can increase the update rate first, then select to match The resolution is flexible to meet the needs of the user and does not have to be accommodating to established standards.

Furthermore, since the display capability identification data compiling module of the present invention does not issue the display card trigger signal immediately when the first connection port is connected to the display card, but the display capability identification data has been completely written into the first storage unit. Therefore, the timing schedule of the controllable tube read/write data does not collide, and the edit display capability identification data is not compiled and written by the display card before the completion of writing, and the display card reading error can be avoided.

In addition, since the function of compiling data is provided by the display capability identification data compiling module, and the data control module does not need to have the firmware function, it only needs to be responsible for data transmission between the first storage unit and the display card. Such wafer In order to connect the display card, it is less likely to have compatibility problems, and the display card can be prevented from reading the display capability recognition generator.

Referring to FIG. 1 and FIG. 2, the display capability recognition generator 9 of the present invention includes: a first port 10 for connecting to a display card 200; and a second port 20 for Connected to a display 210; a first storage unit 30 stores the set display capability identification data; a data control module 40 is connected to the first port 10 and the first storage unit 30, and has a The first card 10 is connected to the display card trigger terminal 41, and stores a display card trigger signal; a display capability identification data compiling module 50 is connected to the data control module 40 and the second port 20, and is compiled. A display capability identification data is generated. An operation interface 60 is connected to the display capability identification data compilation module 50. In the embodiment, the operation interface 60 includes a plurality of keys 61 and a display screen 62. The plurality of operation instructions are respectively output for operation, and the display screen 62 displays the display capability identification data for the user to observe as a basis for editing.

Referring to FIG. 3, the display capability identification generator 9 compiles the display capability identification data and provides the display card 200 reading system. The method includes the following steps: the display capability identification data compilation module 50 operates according to the operation interface 60. Compiling to generate a corresponding display capability identification data S10; After the display capability identification data is completed, the display capability identification data compiling module 50 outputs the display capability identification data to the data control module 40 (S20); after receiving the display capability identification data, the data control module 40 receives the display capability identification data. The display capability identification data is written into the first storage unit 30 (S30). In this embodiment, after the display capability identification data is written, the data control module 40 outputs a completion message to the display capability identification. The data compiling module 50, the display capability identification data compiling module 50, after detecting that the data control module completes the writing of the display capability identification data, causes the data control module to output the display card trigger signal S40 to drive the display. The card begins to read the display capability identification data written in the first storage unit 30 through the data control module 40. In this embodiment, the display capability identification data compilation module 50 causes the data to be received after receiving the completion message. The control module 40 outputs the display card trigger signal.

The display capability identification data compiling module 50 can further be provided with a second storage unit 51, and the second storage unit 51 has built-in standard display capability identification data formulated by the VESA for selection by the display capability identification data compiling module 50. Read any standard display capability identification data output to the data control module 40, and then write to the first storage unit 30. In addition, the display capability identification data compilation module 50 further defines an identification data copy mode and an identification. In the data overwrite mode, when the identification data copy mode is executed, the display capability identification data built in the display is retrieved from the second port 20 for output to the data control module 40 for performing the identification data overlay. In the write mode, the display capability identification data compiled according to the operation of the operation interface 60 is written in the display connected to the second port 20.

The standard display capability identification data formulated by the above plurality of VESAs is further divided into a single link data set (Single Link table) and a double link data set (Dual Link table), because the output bandwidth of the single-link display card can only be reached. 165Mb/s, dual-link display card can be up to 330Mb/s, so the corresponding display capability identification data is different (such as double-link display card can provide higher update rate compared with the same resolution) The invention divides all the developed standard display capability identification data into a set of single-link data sets and a set of double-link data sets, and the user can quickly find suitable ones from the corresponding data sets according to the display card specifications. Resolution and update rate.

The first storage unit 30 further includes a plurality of compiled data storage areas 31 for the display capability identification data compilation module 50 to further select the compiled display capability identification data stored in the first storage unit 51. The area 31 is provided for the user to store the commonly used display capability identification data in the first storage unit 30, and can be quickly read out when the next time to use, without re-editing; the first storage unit 30 can be The display rotation angle control command is further stored to control the display screen 62 to display the rotation of the screen.

Moreover, since the display capability identification data includes a type of digit definition bit, the display capability identification data compiling module 50 defines the bit by setting the analog digit in the display capability identification data to control the display card to change the digital or analog display. For the purpose of information, there is no need to separate analog wafers and digital chips to reduce the number of unnecessary wafers.

Since the data connection device of the conventional display and the operation principle of the conventional display capability recognition device all use the built-in display capability to identify the data, and actively notify the display card to read the display capability identification data, the original power must be greatly modified. The road architecture can further provide the function of editing the display capability identification data, otherwise the display will read the incomplete display capability identification data. To this end, the present invention displays the function of the data read/write schedule provided by the capability recognition generator 9: When the data control module 40 is connected to the display card 200, the trigger signal is not actively sent, but the display capability identification data compiling module 50 confirms that the data control module 40 completes the display capability identification data writing operation. The data control module 40 outputs a trigger signal, so that the display card 200 reads that the complete display capability identification data has been written, thereby ensuring that the display card 200 does not read the incomplete display capability identification data, thereby further ensuring normal operation.

The editing function and timing control of the display capability recognition generator of the present invention have been described above, and the following is a further example of its operation:

1. Overclocking use: When the user connects the display capability recognition generator to the display card 200 and the display 210, the display card 200 reads the display capability identification data in the first storage unit 30 of the display capability recognition generator 9. The user can set the highest resolution and update rate that can be supported by the display card 200 and the display 210 by editing the display capability identification data. The following is an example: a single-link display card 200 of a brand is connected with a resolution of 1920. After the display 210 of ×1200 and the update rate of 60Hz, after testing, if the resolution of 2560×1200 is used, and the update rate of 60Hz is used, the bandwidth will be as high as 180Mb/s, as described above, the single-link display card 200 and the display 210 cannot provide the bandwidth. At this time, the display card 200 will automatically change the resolution of 2560×1200 to a resolution that cannot be predicted by the user, and cannot display the display 210 properly, and cooperate with the present invention. The display capability recognition generator edits a resolution of 2560×1200, and with a 50Hz update rate, the bandwidth will be reduced to 161Mb/s, and the display card is sufficient to support this bandwidth. The display 210 can be normally displayed on the screen, and if the user only needs to play the slide or dynamic album, the reduction of the update rate has almost no effect on the delicateness of the action (the human eye can not distinguish the difference), and the user can visually Need to adjust, that is, to achieve overclocking use of the display 210.

2. Solving the problem that the display card 200 and the display 210 are connected for a long distance: since the hospital and the like often need to connect the computer host and the display 210 with wires exceeding hundreds of meters or more, after the signal is attenuated, the display card 210 often cannot be read. The display capability identification data built in the display 210, the present invention provides an identification data copy mode, and the display capability recognition generator 9 can be first connected to the display 210 in close proximity. As shown in FIG. 4, the display capability identification data of the display 210 is copied. After being stored and stored, it is changed to be closely connected to the display card 200. As shown in FIG. 5, the display card 200 can read the display capability identification data identical to the display 210.

In summary, the function of the display and display capability identification data provided by the present invention allows the user to edit and try to use VESA standard or non-standard display capability identification data on the display card to find the most suitable requirement. The resolution and update rate, and the overclocking operation of the display, and the display capability recognition generator of the present invention can also prevent the display card from reading the incomplete display capability identification data while avoiding compatibility while providing the editing function. The problem is to greatly enhance the functions that are lacking in the existing display capability recognition device, and to make the use condition, compatibility and function complete.
