Description

Smart Extended Display Identification Data Simulator

This author is about a smart extended display identification data simulator, especially using the main control unit to automatically read the extended display capability identification data of the display and store it in the memory unit, so that the system main chip of the overall system can be ignored. Whether there is a case where the display is changed to another type of display, and the extended display capability of the memory unit is used to directly identify the data, and the desired picture is transmitted to drive all the displays, so the user does not need to manually set the relevant necessary parameters, thereby greatly simplifying the operation. Procedures to avoid human error and solve compatibility problems at the same time.

Generally, the computer system uses the display to realize the image display function, but the display produced by each manufacturer may have different display characteristics, such as resolution or screen size. Therefore, the display is extended display identification data. , referred to as EDID) for system reading and setting, such as including the basic display parameters of the display, such as manufacturer ID, production ID code, manufacturing week, manufacturing year, basic display parameters, chroma adjustment, clock generation, setup time Pulse II, manufacturer-reserved clock, detailed clock description 1~4, extra flag, checksum, or, further, image input definition, maximum horizontal graphic size, maximum vertical graphic size, Displays gamma, power management, and support features.

Usually, the EDID is stored in the PROM or EEPROM of the display, and the computer system can read the EDID data through I2C, and the default value of the slave address is 0x50.

However, users often encounter the following problems.

Problem 1: When the screen is replaced, if the display screen under the Windows operating system (Window XP, Win7 or Win8) becomes smaller and cannot fill the entire screen, the display parameters need to be adjusted correctly. It is usually set to change the resolution and change the zoom ratio to "full screen" so that the screen size can fill the entire viewing range of the screen. However, for a large number of users who are not familiar with computer settings, the actual setting operation is quite complicated and inconvenient. For example, when using an nVidia display card, an AMD_ATI display card, or Intel built-in display function, different corresponding setting methods are required.

Question 2: When the multi-screen is used, if the driver has been reinstalled, the digital kanban software identification is no problem and has been set. However, if there is a problem with the screen that must be replaced, the digital kanban software must also be re-arranged to arrange the new screen sequence, which is not convenient for the average user.

Question 3: A recognition error occurs after the screen is connected. In other words, if you want to connect the computer to the KVM or the extender of the audio and video signals, when the "computer" and the "screen" are connected in series, these signals are switched, assigned or extended. After the equipment, the computer will recognize the resolution of the display. For example, the best mode for a 24-inch display is 1920x1080. After the signal is connected in series, the resolution of the computer suddenly cannot be found in the display setting, or the screen display cannot fill the screen, the color is incorrect, etc. How to adjust will not work. This happens because the computer detects the display's EDID data and cannot be correctly identified. When the user connects KVM, HDMI, DVI splitter, DVI switch or Cat.5 extender in series, it will easily occur and cannot be correctly identified. The situation of EDID information.

Therefore, there is a great need for an innovative smart extended display identification data simulator that uses the main control unit to automatically read the extended display capability identification data of the display and store it in the memory unit, thus the system master of the overall system (such as a computer system). The chip can directly use the extended display capability of the memory unit to identify the data regardless of whether the display is replaced with another type of display, and transmit the desired picture to drive all the displays, so the user does not need to manually set the relevant The necessary parameters greatly simplify the operation procedures and avoid human error, so as to solve the problem of compatibility and solve the problems of the above-mentioned conventional technologies.

And transfer the display link configuration data.

Furthermore, the memory unit receives and stores the extended display identification data corresponding to each display from the main control unit, and also receives and stores the display connection configuration data from the main control unit. The transmission unit is connected to the display card, and under the control of the main control unit, the extended display identification data and the display connection configuration data are transmitted to the display card according to the display data request from the display card.

Further, the system main chip is after executing the operating system (such as Microsoft Windows), and when the smart extended display identification data simulator reading function is activated, the display card can be driven to present the display to the smart extended display identification data simulator. The data request is used to receive the extended display identification data from the display card and the display link configuration data, and dynamically update the driver corresponding to the at least one display. In addition, the data emulator may be identified by the display card and the smart extended display, and the corresponding at least one display screen is transmitted to the at least one display for individual display.

Obviously, since the intelligent extended display identification data simulator of the present invention uses the main control unit to automatically read the extended display capability identification data of the display and store it in the memory unit, the system main chip of the overall system (such as a computer system) can be In the case of ignoring whether or not the display is further integrated into another type of display, the information of the extended display capability of the memory unit is directly used to transmit the desired picture to drive all the displays, so the user does not need to manually set the relevant necessary parameters. , greatly simplify the operation procedures, avoid human error, and indeed solve the compatibility problem.

The implementation of the present invention will be described in more detail below with reference to the drawings and component symbols, so that those skilled in the art can implement the present specification after studying the present specification.

Referring to the first figure, a schematic diagram of the intelligent extended display identification data simulator of the first embodiment of the present invention is shown. As shown in the first figure, the smart extended display identification data simulator 10 of the present embodiment is connected to at least one display 20 and the display card 30, and includes a reading unit 12, a main control unit 14, a memory unit 16, and a transmission unit 18. The reading unit 12, the memory unit 16, and the transmission unit 18 are connected to the main control unit 14, and the main control unit 14 controls the electrical operation functions of the reading unit 12, the memory unit 16, and the transmission unit 18. In addition, the reading unit 12 is connected to each display 20, and the transmission unit 10 is connected to the display card 30 located on the motherboard (not shown), and the display card 30 is further connected to the system main chip located on the same motherboard. 40 (also known as CPU, CPU).

Specifically, each display 20 has an individual extended display identification data (EDID), and the display card 30 is connected to each display 20 through an image transmission interface, wherein the image transmission interface can include general VGA, DS-sub or HDMI.

The main control unit 14 can automatically detect whether the display 20 is connected to the reading unit 12, and then read the extended display capability identification data (EDID) of each display 20, while being connected to the reading unit 12 according to each display 20. Link the configuration and establish the corresponding display link configuration data. In addition, the main control unit 14 transfers the extended display identification data and the display connection configuration data to the memory unit 16 for storage for later reading by the main control unit 14.

Furthermore, the transmission unit 18 is connected to the display card 30 for transmitting the extended display identification data and the display connection configuration data to the display card 30 according to the display data request from the display card 30 under the control of the main control unit 14. .

Further, the system main chip 40 is executed under a specific operation system (such as Windows or Linux), and after driving the preset smart extension display identification data simulator reading function, the display card 30 is driven. The intelligent extended display identification data simulator 10 of the present invention proposes the above-mentioned display data request, and further receives the extended display identification data from the display card 30 and the display connection configuration data, and dynamically updates each display 20 accordingly. The driver (Motor) simultaneously transmits the corresponding at least one display screen to the at least one display 20 via the display card 30 and the smart extended display identification data simulator 10 for individual display.

In addition, the main control unit 14 can be implemented by a microcontroller (MCU) or a microprocessor, or the reading unit 12, the main control unit 14 and the transmission unit 18 can be integrated into a single chip of high functionality.

It is to be noted that the system main chip 40 can also activate the display card 30, and directly read the extended display capability identification data of each display 20 via the image transmission interface, thereby completing the configuration of each display 20. The displayed picture is displayed correctly.

Further, the automatic learning mode can detect the types of all the displays currently used (such as CRT, DVI, HDMI, etc.), and download and store the related data (ie, EDID), waiting for the display card 30 to perform call processing. When the main control chip 14 is in the automatic learning mode, it is possible to select to store the first used display 20 or the last used display 20, and wait for the display card 30 to read after setting the relevant data.

In addition, the manual mode can use the communication interface (such as RS232) to directly set the resolution and model data of the display 20, which can effectively avoid the compatibility problem of the display 20 (such as poor device signal) or environmental factors (device The power supply sequence is different), resulting in software problems. Moreover, when in the manual mode, relevant information (such as resolution and model number) can be provided by the software, and the main control chip 14 is notified by the communication interface, and after the data setting is completed, the display card 30 is triggered to request to re-detect all. Display 20.

In practical applications, if only the single display 20 is configured, since the smart extended display identification data simulator 10 automatically reads and stores the extended display capability identification data of the display 20, the system main chip 40 does not need to read the display 20 By extending the display capability identification data, the information stored in the data simulator 10 is directly recognized by the smart extension display, and thus the overall operation is simple. In particular, when the user replaces the display 20 and if the updated display 20 has different extended display capability identification data, the system main chip 40 only needs to update the driver and the screen display according to the data from the smart extended display identification data simulator 10. With the resolution, the desired picture can be correctly displayed on the updated display 20. There is no compatibility problem, and the user does not need to start the display setting function under the operating system and troublesomely sets various necessary parameters to achieve the insertion. The purpose of use.

For applications using multiple displays 20, such as large digital display devices like video walls, the simulator of the present application will automatically store the updated information of the display 20, regardless of the number of displays 20 replaced by the user. The system main chip 40 does not need to pay attention to whether the display 20 has been replaced, and the screen is displayed on all the displays 20 by correctly using the required driver according to the data currently stored by the smart extension display identification data simulator 10. For example, when the system main chip 40 continuously displays the desired picture on the plurality of displays 20 displayed on the matrix arrangement, it also causes a marquee effect even if one of the displays 20 is replaced with another one due to damage or malfunction. When the manufacturer's different types of displays 20 are in place, the system master wafer 40 can still drive all of the displays 20 to display the screen without having to reset the necessary parameters.

In summary, the main feature of this creation is that the main control unit automatically reads the extended display capability identification data of the display and stores it in the memory unit, so that the system main chip of the overall system (such as a computer system) can be ignored. In the case where the display is further integrated into another type of display, the extended display capability of the memory unit is used to directly identify the data, and the desired picture is transmitted to drive all the displays, so that the user does not need to manually set relevant necessary parameters, thereby greatly simplifying the operation. Procedures to avoid human error and solve compatibility problems at the same time.
