[0039] The computer is electrically connected to the display, so that the calibration data generated by the computer based on the color data can be transmitted to the display, and the display can display based on the calibration data.

[0040] Furthermore, the acquisition end is configured as a measuring optical device, wherein the measuring optical device includes:

[0041] The incident section allows light from the object being measured to enter;

[0042] The photoelectric conversion unit converts the received light into an electrical signal;

[0043] A light guide section that guides light incident through the incident section to the photoelectric conversion section;

[0044] A first substrate for mounting a first electronic device and a second substrate for mounting a second electronic device are disposed around the optical axis of the light guide portion, and are arranged circumferentially offset from each other in such a way that the temperature distribution on the first substrate side and the temperature distribution on the second substrate side of the light guide portion are symmetrical about the optical axis of the light guide portion.

[0045] Furthermore, when viewed from the optical axis direction of light incident through the incident portion, the first substrate and the second substrate are arranged opposite each other across the light guide portion.

[0046] Furthermore, on the first substrate, a control unit for controlling the measurement operation of the optical device for measurement is installed as the first electronic device, and on the second substrate, a power supply unit for transforming the power supplied from the outside is installed as the second electronic device.

[0047] Furthermore, the light guide includes an optical fiber and a protective component, wherein the optical fiber allows light to propagate, and the protective component is arranged to cover the optical fiber to protect it.

[0048] Furthermore, an air layer is formed between the optical fiber and the protective component.

[0049] Furthermore, the protective component is made of metal and conducts heat circumferentially through the optical fiber.

[0050] Furthermore, the protective component is formed of a heat-insulating material.

[0051] Furthermore, the light guide portion has a first opposing surface opposite to the incident portion and a second opposing surface opposite to the photoelectric conversion portion in the optical axis direction of the light incident through the incident portion, and the first substrate and the second substrate are disposed between the first opposing surface and the second opposing surface in the optical axis direction of the light incident through the incident portion.

[0052] Furthermore, the computer is electrically connected to the display, enabling the calibration data generated by the computer based on the color data to be transmitted to the display, and allowing the display to display based on the calibration data, including:

[0053] The calibration data generated by the computer based on the color data is converted into color value data in RGB color mode through the communication protocol between the computer and the monitor.

[0054] The display is based on the color value data.

[0055] In practical applications, each of the acquisition terminals is positioned at the location of a screen, enabling the acquisition terminal to obtain the screen's color data during operation, including:

[0056] The data acquisition device is placed close to the screen;

[0057] Furthermore, the incident part of the acquisition end is aligned with the screen, and the distance is within 3 centimeters;

[0058] Furthermore, the acquisition end is fixed to the front of the display by a bracket, and the incident part of the acquisition end is aligned with the screen, with the distance being within 1 cm.

[0059] Furthermore, a connecting wire extends from the end of the acquisition end (i.e., the end without the incident part) and connects to the computer end;

[0060] Furthermore, the computer is connected to the monitor via a cable and transmits calibration data to the monitor, so that all screens of the monitor display based on the calibration data.

[0061] In practical applications, color adjustment refers to adjusting the screen LEDs so that all LEDs display according to the proportions of each color value in the RGB color mode, resulting in different display effects.

[0062] HDMI stands for High Definition Multimedia Interface, which is a fully digital video and audio transmission interface that can transmit uncompressed audio and video signals.

[0063] DisplayPort (DP) is a digital video interface standard developed by a consortium of PC and chip manufacturers and standardized by the Video Electronics Standards Association (VESA). This interface requires no certification or licensing fees and is primarily used for connecting video sources to devices such as monitors. It also supports carrying audio, USB, and other forms of data.

[0064] In this manual, "connecting via HDMI or DisplayPort" refers to connecting via a data line compatible with the High Definition Multimedia Interface (HDMI) or a data line compatible with the DisplayPort interface; in Figure 1, the arrow "HDMI / DisplayPort" indicates the aforementioned connection via HDMI or DisplayPort; in Figure 1, the arrow "USB" indicates a connection via a line compatible with the USB standard, where USB stands for Universal Serial Bus, a serial bus standard and an input / output interface specification; in Figure 1, the host computer software refers to the pre-installed software on the computer, and the operating principle of this software is shown in Figures 2 and 3.

[0065] In Figure 2, x and y represent a set of color data; "Adjust the RGB data of the monitor" means adjusting the color value data in the RGB gain and making the monitor display the adjusted color value data; in Figure 2, judging whether the set value has been reached means comparing the current color data with the preset set value range. If the current color data falls into the preset set value range, "yes" is output, otherwise "no" is output.

[0066] Figure 3 illustrates an algorithm logic for calibrating the brightness of dual screens. The corresponding software runs on a computer. The maximum brightness shown in Figure 3 is the maximum brightness that the monitor screen can display. The two screens of the monitor are denoted as the upper screen and the lower screen. In the figure, "upper screen > lower screen?" indicates that a judgment is made to determine whether the brightness of the upper screen is greater than that of the lower screen. If so, the upper screen is calibrated; if not, the lower screen is calibrated.

[0067] Calibration process: Connect the monitor via HDMI or DisplayPort, and obtain the current color values ​​x, y, etc. using a color analyzer such as CA310 or CA410. Adjust the R, G, and B values ​​of the monitor to make the x and y values ​​obtained by the monitor in real time equal to the set values ​​(within a certain range). The adjusted data is dynamically adjusted to adjust the color values ​​of the monitor through the DDCCI communication protocol (communication between the computer and the monitor).

[0068] In practical applications, the aforementioned x and y values ​​can be the x and y values ​​in the CIE-1931 standard; in another implementation, obtaining the current color value includes obtaining the x, y, and T values ​​under the CIE-1931 standard.

[0069] Dual-screen calibration: Since the top and bottom screens exist independently, both screens need to be calibrated, and the process is the same.

[0070] Dual-screen brightness calibration: Because the brightness of the upper and lower screens differs, it is necessary to adjust the brightness to bring the brightness of the upper and lower screens within a certain range.

[0071] In the embodiments of this utility model, a multi-screen color calibration system is provided, which realizes color calibration of display devices with two (or more) screens through a complete system, which is convenient for users to operate. At the same time, a multi-screen color calibration system includes a monitor and a computer with pre-installed software, which can realize automatic calibration of the monitor's color, thus solving the problems in the prior art.

[0072] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included in this invention.
