DETAILED DESCRIPTION

[0010] One of the purposes of the present invention is to provide a display device with a screen function display screen control mechanism and a screen function display screen control method thereof. By setting up a signal transmission circuit, it has the functions of transmitting keyboard input signals to a computer host and using the keyboard input signals to directly adjust the screen function display screen without identifying position information.

[0011] Please refer to Figure 1 . Figure 1 The circuit diagram of a display device 100 with an on-screen display control mechanism in one embodiment of the present invention is shown. The display device 100 includes a signal receiving port 110 , a signal transmitting circuit 120 , a display panel 130 and a display control circuit 140 .

[0012] The signal receiving port 110 is configured to receive a keyboard input signal KIS. In one embodiment, the signal receiving port 110 is, for example, but not limited to, a universal serial bus (USB) connection interface, which is electrically coupled to a keyboard 150 outside the display device 100 and receives the keyboard input signal KIS from the keyboard 150. The keyboard 150 includes a plurality of keys.

[0013] The signal transmission circuit 120 includes an input terminal IN, a first output terminal O1, and a second output terminal O2. The signal transmission circuit 120 may be, for example, but not limited to, a hub of a universal serial port transmission interface, and is configured to receive the keyboard input signal KIS from the signal receiving port 110 via the input terminal IN. The signal transmission circuit 120 may transmit the keyboard input signal KIS to at least one of the first output terminal O1 and the second output terminal O2 according to different operation modes.

[0014] In the keyboard signal transmission mode, the signal transmission circuit 120 transmits the keyboard input signal KIS to the first output terminal O1. In one embodiment, the first output terminal O1 is electrically coupled to a computer host terminal 160 of the display device 100. In one embodiment, the electrical coupling between the computer host terminal 160 and the first output terminal O1 of the display device 100 is performed through a path such as, but not limited to, a Type-C universal serial port specification to achieve the purpose of bidirectional transmission.

[0015] Therefore, the computer host end 160 can transmit display data (not shown) to the display device 100 via the path between the above-mentioned first output end O1 and the computer host end 160, and for example, transmit the display data to the display control circuit 140 through the path (not shown) between the first output end O1 and the display control circuit 140 in the display device 100, and then display it on the display panel 130 after processing.

[0016] At the same time, the display device 100 can also transmit the keyboard input signal KIS to the computer host end 160 through the first output end O1 and the path between the first output end O1 and the computer host end 160 by setting the signal transmission circuit 120 to control the computer host end 160.

[0017] On the other hand, in the screen function display image control mode, the signal transmission circuit 120 transmits the keyboard input signal KIS to the second output terminal O2 . In one embodiment, the second output terminal O2 is electrically coupled to the display control circuit 140 .

[0018] The display control circuit 140 is electrically coupled to the signal transmission circuit 120 and the display panel 130. The display control circuit 140 is configured to control the display panel 130 to display a screen function display screen including a plurality of control options and an indicator object in a screen function display screen control mode, wherein one of the control options indicated by the indicator object is selected as a selected control option.

[0019] Please refer to FIG. 2A to FIG. 2D . FIG. 2A to FIG. 2D A schematic diagram showing a screen function display screen 200 displayed by the display panel 130 in one embodiment of the present invention.

[0020] like Figure 2A As shown, the screen function display screen 200 includes a plurality of control options 210A-210C and an indication object 220. The control options 210A-210C are, for example, but not limited to, menu options including image parameters, color parameters, and size parameters.

[0021] Indicator 220 Figure 2A The middle is a thick frame indicating the control option 210B, and the indicated control option 210B is selected as the selected control option. In other embodiments, the indicating object 220 may also be a color layer or a highlight layer covering the control option, or may be any other display object that can be used to select the control option. The present invention is not limited to this.

[0022] The display control circuit 140 is configured to receive the keyboard input signal KIS from the second output terminal O2 to extract key information (not shown) of the keyboard input signal KIS.

[0023] In one embodiment, the keyboard input signal KIS includes human interface device (HID) descriptor information. The display control circuit 140 is configured to extract key information related to the keyboard 150 from the HID descriptor information, wherein the key information is information corresponding to the physical key on the keyboard 150 that is triggered.

[0024] In one embodiment, the signal transmission circuit 120 is configured to convert the human body interface device description metadata into a format, such as but not limited to, into I 2 C format, so that the display control circuit 140 can extract the key information from the HID description meta-information after the format conversion.

[0025] The display control circuit 140 recognizes the key information as direction information or operation information according to internal firmware (not shown).

[0026] When the display control circuit 140 recognizes the key information as direction information, it moves the indication object 220 between the control options to change the indicated selected control option.

[0027] For example, in Figure 2A In the case of Figure 1 The key information corresponding to the "up" key 170A and the "down" key 170B included in the keyboard 150 is recognized as direction information. When the key information received by the display control circuit 140 is generated according to the "up" key 170A, Figure 2B It is shown that the indicating object 220 is moved to the control option 210A, and the indicated control option 210A is selected as the selected control option.

[0028] The display control circuit 140 performs the control function corresponding to the selected control option when the key information is recognized as operation information. In one embodiment, the control function includes entering a next menu and causing the indicator object 220 to indicate one of the control options included in the next menu, exiting to a previous menu and causing the indicator object 220 to indicate one of the control options included in the previous menu, or adjusting the screen display parameters of the display panel 130 corresponding to the selected control option.

[0029] For example, in Figure 2B In the case of Figure 1 The key information generated by the "enter" key 170C included on the keyboard 150 is recognized as operation information, and Figure 2CAs shown, the next menu of the control option 210A corresponding to the image parameter is entered. At this time, the menu of the control option 210A includes control options 210D-210F, which are screen display parameter control options such as, but not limited to, brightness, contrast and sharpness.

[0030] When entering the menu of control options 210A, the display control circuit 140 synchronously causes the indicating object 220 to indicate one of the control options included in the menu, such as but not limited to Figure 2C , and the control option 210D is selected as the selected control option.

[0031] exist Figure 2C In the case of Figure 1 The key information corresponding to the "left" key 170D and the "right" key 170E included in the keyboard 150 is recognized as operation information. When the key information received by the display control circuit 140 is generated according to the "right" key 170E, Figure 2D The brightness parameter corresponding to the selected control option (control option 210D) is adjusted to increase the brightness.

[0032] In addition, Figure 2C In the case of Figure 1 The key information generated by the "backspace" key 170F included on the keyboard 150 is recognized as operation information, and Figure 2B The indicator 220 indicates one of the control options included in the previous menu, such as but not limited to Figure 2B , so that control option 210A is selected as the selected control option.

[0033] Therefore, by setting the signal transmission circuit 120, the display device 100 of the present invention can transmit the keyboard input signal KIS of the keyboard 150 to the computer host end 160 in the keyboard signal transmission mode to serve as a signal relay transmission. Furthermore, in the screen function display screen control mode, the display device 100 controls the screen function display screen 200 by the keyboard input signal KIS of the keyboard 150 to adjust the screen display parameters of the display panel 130. The display device 100 can achieve the effect of directly controlling the screen function display screen 200 without identifying the position information while transmitting the keyboard signal.

[0034] It should be noted that the configuration of the buttons corresponding to the direction information and the operation information is only an example. In other embodiments, corresponding to the control option arrangement logic included in the screen function display screen, the keyboard 150 can also be configured so that the button information corresponding to the "up" button and the "down" button is recognized as the operation information, and the button information corresponding to the "left" button and the "right" button is recognized as the direction information. In addition, other buttons included in the keyboard 150, such as letter buttons, number buttons, and function buttons, can also be configured to correspond to the direction information and the operation information. The present invention is not limited to this.

[0035] In one embodiment, the keyboard input signal KIS is generated by a plurality of specific keys or a plurality of non-specific keys corresponding to the keyboard 150. The specific keys are, for example but not limited to: Figure 1 The buttons 170A to 170F are shown in gray blocks. Non-specific buttons are, for example but not limited to Figure 1 Other buttons are shown in white blocks.

[0036] The signal transmission circuit 120 is further configured to transmit the keyboard input signal KIS generated by the non-specific key to the first output terminal O1 in the keyboard signal transmission mode and the screen function display image control mode.

[0037] In this case, even in the screen function display screen control mode, the user can still control the computer host end 160 electrically coupled to the first output end O1 by using the non-specific keys of the keyboard 150, and control the screen function display screen 200 by using the specific keys of the keyboard 150. Therefore, in the screen function display screen control mode, the display screen displayed by the computer host end 160 on the display panel 130 and the screen function display screen 200 can be operated simultaneously without affecting each other.

[0038] In one embodiment, the switching of the operation modes is performed according to a combination key signal formed by a plurality of keyboard input signals KIS simultaneously generated by the keyboard 150 , and these keyboard input signals KIS may be generated by a user pressing a plurality of keys of the keyboard 150 simultaneously.

[0039] For example, when the "Shift" function key, the "Alt" function key, and the "O" letter key included in the keyboard 150 are pressed simultaneously, the three keyboard input signals KIS generated simultaneously by these three keys will form a combined key signal and be used to switch the operation mode. It should be noted that the above key combination is only an example. In other embodiments, the combined key signal can also be generated by a combination of different numbers and different keys. The present invention is not limited to this.

[0040] In one embodiment, the signal transmission circuit 120 is further configured to transmit the keyboard input signal KIS to the second output terminal O2 in the keyboard signal transmission mode, so that the display control circuit 140 controls the signal transmission circuit 120 to switch between the keyboard signal transmission mode and the screen function display image control mode according to the combined key signal formed by the multiple keyboard input signals KIS simultaneously generated by the keyboard 150. The signal transmission circuit 120 further stops transmitting the keyboard input signal KIS corresponding to the specific key to the first output terminal O1 in the screen function display image control mode.

[0041] In another embodiment, the keyboard signal transmission mode and the screen function display screen control mode are determined by the display control circuit 140. For example, the display control circuit 140 monitors the combination key sent by the signal transmission circuit 120 to switch to the display control, and when receiving the combination key signal, the subsequent keyboard input signal KIS is transmitted only to the second output terminal O2 according to the keyboard signal transmission mode and the screen function display screen control mode, and the output of the first output terminal O1 is terminated to avoid affecting the operation of the original program of the computer host terminal 160. After the display control operation is completed, the signal transmission circuit 120 transmits the keyboard input signal KIS to the first output terminal O1 and the second output terminal O2 respectively at the same time, and the display control circuit 140 continues to monitor the switch combination key.

[0042] Please refer to Figure 3 . Figure 3 A flowchart of a screen function display image control method 300 is shown in one embodiment of the present invention.

[0043] In addition to the aforementioned device, the present invention further discloses a screen function display image control method 300, which is applied to, for example, but not limited to Figure 1 In the display device 100. An embodiment of the screen function display picture control method 300 is as follows Figure 3 As shown, the following steps are included.

[0044] In step S310 , a keyboard input signal KIS corresponding to a keyboard is received by the signal receiving port 110 .

[0045] In step S320 : it is determined whether the signal transmitting circuit 120 is in the keyboard signal transmission mode.

[0046] In step S330: when the signal transmission circuit 120 is not in the keyboard signal transmission mode, it is determined that the signal transmission circuit 120 is in the screen function display image control mode, so as to receive the keyboard input signal KIS from the signal receiving port 110 through the input terminal IN, and transmit the keyboard input signal KIS to the second output terminal O2.

[0047] In step S340 , the display control circuit 140 is enabled to control the display panel 130 to display a screen function display screen 200 including a plurality of control options (eg, control options 210A-210F) and an indicator object 220 in the screen function display screen control mode, wherein one of the control options indicated by the indicator object 220 is selected as a selected control option.

[0048] In step S350 : the display control circuit 140 receives the keyboard input signal KIS from the second output terminal O2 to extract key information of the keyboard input signal KIS.

[0049] In step S360 , the display control circuit 140 controls the indication object 220 to move between the control options according to the key information to change the indicated selected control option or execute the control function corresponding to the selected control option.

[0050] In step S370 , when the signal transmission circuit 120 is in the keyboard signal transmission mode, the keyboard input signal KIS is received from the signal receiving port 110 via the input terminal IN, and the keyboard input signal KIS is transmitted to the first output terminal O1 , and further transmitted to the computer host terminal 160 .

[0051] It should be noted that the above implementation is only an example. In other embodiments, those skilled in the art may make changes without violating the spirit of the present invention.

[0052] In summary, the display device with a screen function display image control mechanism and the screen function display image control method of the present invention can, through the setting of a signal transmission circuit, both transmit keyboard input signals to the computer host end and use the keyboard input signals to directly adjust the screen function display image without identifying position information.
