Description

Technical Field

[0001] The present invention relates to an electronic device, and in particular to an electronic device capable of controlling a privacy area. Background Art

[0002] Electronic devices including displays have been widely used in daily life, such as car displays, notebook and personal computer displays, interactive multimedia information stations (kiosks), and automatic teller machines (ATMs). Currently, some electronic devices can adjust the viewing angle of the display or a portion thereof to reduce the angle at which the display can be seen by others other than the user, thereby achieving an anti-peeping function and protecting the user's privacy.

[0003] However, for different users, the anti-peeping area on the display that needs to use the anti-peeping function is different in position and size. Moreover, for the same user, when the display is used to display different information, the required anti-peeping area will also be different.

[0004] Therefore, solving the above problems becomes an important issue. Summary of the invention

The display device includes a display unit for displaying an image; a processing unit electrically connected to the display unit and defining the anti-peeping area according to a predefined anti-peeping requirement; and a light control unit electrically connected to the processing unit and controlling the light output angle of the anti-peeping area.

[0006] An embodiment of the present invention provides a display device for controlling an anti-peeping area. The display device includes a display unit for displaying an image; a touch unit electrically connected to the display unit and determining the anti-peeping area through the touch unit; and a light control unit electrically connected to the touch unit and controlling the light output angle of the anti-peeping area.

[0151] Figure 2 2 is a flow chart of a method 200 for controlling a display of an anti-peeping area according to an embodiment of the present invention. FIG. 3A to FIG. 3D According to an embodiment of the present invention, Figure 2 A simplified schematic diagram of an embodiment of the display method 200 is shown. It should be noted that Figure 2 and FIG. 3A to FIG. 3D The order of operations shown in the figure is only an example, and the order of operations is not limited to Figure 2 and FIG. 3A to FIG. 3D The following will also refer to Figure 2 and FIG. 3A to FIG. 3D The display method 200 is described.

[0152] exist Figure 2 In operation 202, the anti-peeping function is activated. In some embodiments, the user can activate the anti-peeping function by clicking an icon of an application on the touch display. Figure 3A As shown, the user can activate the anti-peeping function by clicking the icon 310 of the application on the touch display 300 of the electronic device. In other embodiments, the user can activate the anti-peeping function by voice, gesture, options on the display, mouse cursor, keyboard key combination, etc., but the present invention is not limited thereto, and the user can use any suitable input means to activate the anti-peeping function.

[0153] exist Figure 2In operation 204, the position, shape and / or size of the privacy protection area is determined. The privacy protection area can be determined by the user and can be any area. In some embodiments, the user can define the position, shape and / or size of the desired privacy protection area on the display by touch function. For example, the user can define (e.g., draw) area 320 on the touch display 300 by touch, where area 320 is the desired privacy protection area desired by the user, such as Figure 3B In other embodiments, the user may define the desired privacy protection area on the display by manipulating the mouse, but the present invention is not limited thereto, and the user may use any suitable input means to define the desired privacy protection area.

[0154] exist Figure 2 In operation 206, it is confirmed whether the area that is about to enter the anti-peeping mode meets the requirements. In some embodiments, the electronic device can display an area that is about to enter the anti-peeping mode on the display, and display a dialog box to ask the user whether the area meets the requirements. For example, the electronic device can display the area 330 that is about to enter the anti-peeping mode in dotted lines on the touch display 300, and display a dialog box 340 to ask the user whether the area meets the requirements, such as Figure 3C In other embodiments, the display may display the area that is about to enter the anti-peeping mode in a solid line, grayscale, etc., but the present invention is not limited thereto.

[0155] When the user confirms that the area to be put into privacy protection mode meets the requirements (for example, by touching or clicking the mouse Figure 3C In the dialog box 340, the method 200 is displayed and proceeds to operation 208. Figure 2 In operation 208, the light pattern of the light emitted from the anti-peeping area is limited. In some embodiments, the electronic device limits the light pattern of the light emitted from the area that is about to enter the anti-peeping mode, so that the area enters the anti-peeping mode and becomes the anti-peeping area. For example, the electronic device limits the light pattern of the light emitted from the area 330 of the touch display 300, so that the area 330 enters the anti-peeping mode and becomes the anti-peeping area 350, as shown in FIG. Figure 3D As used herein, the term "light emission pattern" refers to the angle of light emitted from the display device (i.e., toward the user). In some embodiments, a "restricted" light emission pattern refers to limiting the angle of light emitted from the display device so that the position where the light can be seen is limited to a narrow area in front of the display device. In this way, people outside the area cannot see the content displayed by the display device, thereby achieving the purpose of preventing peeping.

[0156] In some embodiments, the shape of the required privacy protection area defined by the user in operation 204 may be the same as the shape of the privacy protection area actually displayed in operation 208. For example, the electronic device may strictly limit the light pattern of the light emitted by the display device according to the shape of the required privacy protection area defined by the user, so that the shape of the privacy protection area actually displayed is as consistent as possible with the shape of the required privacy protection area defined by the user. In other embodiments, the shape of the required privacy protection area defined by the user in operation 204 may be different from the shape of the privacy protection area actually displayed in operation 208. For example, although the area 320 defined by the user is an ellipse (see Figure 3B ), but the electronic device can appropriately display the privacy protection area 350 (and area 330) as a rectangle (see Figure 3C and Figure 3D In some embodiments, the electronic device may use the horizontal axis and the vertical axis of the required privacy protection area defined by the user as the side lengths to display the privacy protection area actually displayed as a rectangle, but the present invention is not limited thereto.

[0157] When the user confirms that the area to be put into privacy protection mode does not meet the requirements (for example: by touching or clicking the mouse Figure 3C If the user selects "No" in the dialog box 340, the method 200 proceeds to operation 210. Figure 2 In operation 210, the position, shape and / or size of the privacy protection area is re-determined. Operation 210 can be performed by redefining the required privacy protection area in the same or similar manner as the previously described operation 204, so it is not described in detail herein. After operation 210, the display method 200 enters operation 206 again.

[0158] exist FIG. 3A to FIG. 3D In the example shown, FIG. 3A to FIG. 3C It is a non-privacy mode (or normal mode) that has not yet entered the privacy mode. Figure 3D This is an anti-peeping mode, but the present invention is not limited thereto. Figure 3C In the example shown, the area 330 can enter the privacy protection mode while the dialog box 340 is displayed.

[0159] Figure 4 2 is a schematic diagram of an electronic device 100A including a display unit according to some embodiments of the present invention. In some embodiments, the electronic device 100A can be used to implement the display method 200 to control the anti-peeping area, but the present invention is not limited thereto. The electronic device 100A can be similar to the previously described Figure 1 In the electronic device 100 , the same reference symbols represent the same or similar elements, and thus they are not described in detail herein.

[0160] Reference Figure 4, the electronic device 100A includes a display unit 102, a touch unit 106, and a light control unit 108. The display unit 102 is used to display a picture, and may include a panel 104 and a first control circuit 110. The display unit may include a self-luminous display unit and a non-self-luminous display unit. The touch unit 106 is electrically connected to the display unit 102, and may include a touch sensor 180. The light control unit 108 is electrically connected to the touch unit 106, and may include a second control circuit 130. In some embodiments, the light control unit 108 may include one or more of an anti-peeping unit, an anti-peeping light array, an anti-peeping light module, or an anti-peeping film, but the present invention is not limited thereto. In some embodiments, the anti-peeping unit, the anti-peeping light array, the anti-peeping light module, or the anti-peeping film may be controlled by an anti-peeping unit driving circuit 136, an anti-peeping display driving circuit 137, or a backlight unit driving circuit 138. The anti-peeping unit, the anti-peeping light array, the anti-peeping light module, or the anti-peeping film will be described in more detail below.

[0161] The touch unit 106 of the electronic device 100A can be used to determine the anti-peeping area. In some embodiments, the user can define the required anti-peeping area by touch through the touch sensor 180 of the touch unit 106, but the present invention is not limited to this. In other embodiments, the user can define the required anti-peeping area through other suitable input means such as a mouse. Then, the information of the required anti-peeping area can be integrated by a processor included in or coupled to the touch sensor 180 and transmitted to the microcontroller unit 140. Then, the microcontroller unit 140 transmits the information about the required anti-peeping area to the first control circuit 110 of the display unit 102. After the information of the required anti-peeping area is calculated by the algorithm 114, anti-peeping data including the required anti-peeping area will be generated. The multiplexer 120 selects the anti-peeping data generated by the algorithm 114 and outputs the anti-peeping data to the second control circuit 130 of the light control unit 108.

[0162] After receiving the anti-peeping data, the second control circuit 130 outputs the timing and data to the anti-peeping unit driving circuit 136, the anti-peeping display driving circuit 137 or the backlight unit driving circuit 138 according to the anti-peeping data to control the light emission pattern of the anti-peeping unit, the anti-peeping light array or the anti-peeping light module under a certain viewing angle. By controlling the light emission pattern of the anti-peeping unit, the anti-peeping light array or the anti-peeping light module in the desired anti-peeping area, the desired anti-peeping area can enter the anti-peeping mode and become the anti-peeping area.

[0163] The control of the light emission type limits the light emission angle of the anti-peeping area of ​​the display unit so that the light emission intensity is concentrated in a specific area. In some embodiments, the viewing angle is the angle between the line connecting the user's eye to the panel of the display unit and the normal of the panel. For example, the viewing angle may be the angle between the line connecting the user's eye to the center of the anti-peeping area and the normal extending outward from the center of the anti-peeping area. In these embodiments, when the user is directly in front of the panel of the display unit, the viewing angle may be 0 degrees or close to 0 degrees. In alternative embodiments, the viewing angle may be the angle between the line connecting the user's eye to the panel of the display unit and the plane of the panel. In these embodiments, when the user is directly in front of the panel of the display unit, the viewing angle may be 90 degrees or close to 90 degrees.

[0164] In some embodiments, the anti-peeping mode of the anti-peeping area can be released by the following method. A switching control signal can be sent by the microcontroller unit 140 to enable the multiplexer 120 to select the graphics output by the graphic generator 118 to the second control circuit 130. Then, the anti-peeping unit, the anti-peeping light output array or the anti-peeping light output module driven by the second control circuit 130 will stop limiting the light output light type, so that the anti-peeping mode of the anti-peeping area is released. In this way, the entire display unit will enter a non-peeping mode. It should be noted that the above method is only an example of releasing the anti-peeping mode of the anti-peeping area, and the present invention is not limited to this. The anti-peeping mode of the anti-peeping area can be released by any suitable method.

[0165] Figure 5 is a schematic diagram according to an embodiment of the present invention, showing the interaction between the touch sensor and the light control unit when the anti-peep mode is activated. In some embodiments, the touch sensor (e.g., touch sensor 180) may include a touch sensing layer 500, a touch sensing circuit 520 and / or a processor (not shown), but the present invention is not limited thereto. In some embodiments, the touch sensing layer 500 may include an indium tin oxide block (ITO block) or a metal mesh, but the present invention is not limited thereto. In some embodiments, the touch sensing layer 500 may include a sensing unit 510 connected to the touch sensing circuit 520.

[0166] In some embodiments, when the user defines the desired privacy protection area by touch, the sensing unit 510 touched by the user will be activated and Figure 5 The untouched sensing unit 510 remains non-activated and is marked as sensing unit 510A. Figure 5In some embodiments, the activated sensing unit 510A forms a desired privacy protection area 530 of the user. After sensing the desired privacy protection area 530 formed by the sensing unit 510A, the touch sensing circuit 520 transmits the relevant information of the desired privacy protection area 530 to the microcontroller unit 540. The microcontroller unit 540, for example Figure 4 The microcontroller unit 540 then transmits the information about the required privacy protection area 530 to the light control unit 550 .

[0167] In some embodiments, the light control unit 550 includes an anti-peeping unit, an anti-peeping light array, or an anti-peeping light module, but the present invention is not limited thereto. In some embodiments, the light control unit 550 is, for example, the light control unit 108 described previously, and the driving circuit 560 is, for example, the anti-peeping unit driving circuit 136, the anti-peeping display driving circuit 137, or the backlight unit driving circuit 138 described previously, but the present invention is not limited thereto. In some embodiments, after receiving relevant information about the required anti-peeping area 530, the driving circuit 560 of the light control unit 550 controls the light output pattern of the light control unit 550 to limit the light output angle within the required anti-peeping area 530. In this way, the required anti-peeping area 530 enters the anti-peeping mode and becomes the anti-peeping area 570.

[0168] Figure 6 is a schematic diagram according to an embodiment of the present invention, showing Figure 5 The information transmission between the touch sensor and the light control unit is shown. Figure 6 When the user defines the desired privacy protection area 530 by touch through the touch sensor 180, the touch sensing circuit 520 receives the information of the desired privacy protection area 530 formed by the sensing unit 510A on the touch sensing layer 500, and transmits the relevant information of the desired privacy protection area 530 to the microcontroller unit 540. Then, the microcontroller unit 540 synchronizes and transmits the relevant information of the privacy protection area 530 to the driving circuit 560 of the light control unit 550. Then, the driving circuit 560 controls the light output pattern of the light control unit 550 so that the desired privacy protection area 530 becomes the privacy protection area 570.

[0169] Figure 7is a schematic diagram of an electronic device 100B according to some embodiments of the present invention. In some embodiments, the electronic device 100B may be used to implement the display method 200 to control the anti-peeping area, but the present invention is not limited thereto. In some embodiments, the electronic device 100B may include a processing circuit 700, a panel 710 electrically connected to the processing circuit 700, and a driving circuit 720 electrically connected to the processing circuit 700. In some embodiments, the processing circuit 700 may include a touch sensor and / or a processor. In some embodiments, the processor adopts the architecture of an integrated touch display driver (Touch and Display Driver Integration, TDDI) IC, so that the processor can control the touch sensor and the driving circuit 720. In some embodiments, the driving circuit 720 is a driving circuit of a light control unit.

[0170] In some embodiments, the touch sensor of the processing circuit 700 can sense the desired privacy protection area defined by the user. Then, the processor of the processing circuit 700 can drive the driving circuit 720 of the light control unit according to the information of the desired privacy protection area, so that the light control unit controlled by the driving circuit 720 limits the light pattern in the desired privacy protection area. In this way, the desired privacy protection area will enter the privacy protection mode and become the privacy protection area.

[0171] Figure 8 FIG. 8 is a schematic diagram of an anti-peeping unit 800 according to some embodiments of the present invention. In some embodiments, the anti-peeping unit 800 may be applied to Figure 7 In some embodiments, the privacy protection unit 800 includes a first substrate 810, a second substrate 820, a control circuit 860, and a liquid crystal layer (not shown) disposed between the first substrate 810 and the second substrate 820.

[0172] In some embodiments, the first substrate 810 includes a thin film transistor (TFT) array layer. In some embodiments, each thin film transistor is connected to a corresponding pixel electrode, but the present invention is not limited thereto. In some embodiments, the second substrate 820 includes a common electrode layer, which can be applied to an anti-peep drive path and a touch sensing path. In some embodiments, the common electrode layer can be divided into a plurality of sensing units 830, for example, N×M sensing units, where N and M are positive integers greater than 1. In some embodiments, the control circuit 860 is electrically connected to the elements (e.g., thin film transistors, pixel electrodes, and sensing units, etc.) in the first substrate 810 and the second substrate 820 to provide control signals in the touch sensing stage and the display stage, and to sense the sensing unit 830 in the touch sensing stage.

[0173] In some embodiments, when the user defines the desired privacy protection area by touch, the sensing unit 830 touched by the user will be activated, and the activated sensing unit 830 constitutes the desired privacy protection area 840 of the user. Figure 8 In the embodiment, the sensing unit 830 in the required privacy protection area 840 is marked as the sensing unit 830A, and the sensing unit 830 outside the privacy protection area 840 is marked as the sensing unit 830B. After sensing the required privacy protection area 840, the control circuit 860 can make the required privacy protection area 840 enter the privacy protection mode and become the privacy protection area.

[0174] In some embodiments, in the anti-peeping mode, the control circuit 860 can enable the anti-peeping driving path and disable the touch sensing path during the display phase. For example, the control circuit 860 can enable the sensing unit 830A in the required anti-peeping area 840 and the pixel electrode corresponding to the sensing unit 830A to control the arrangement of the liquid crystal between the sensing unit 830A and the pixel electrode. In this way, the light-emitting light type in the required anti-peeping area 840 can be controlled so that the required anti-peeping area 840 enters the anti-peeping mode and becomes an anti-peeping area. At the same time, the control circuit 860 can disable the touch sensing path so that the sensing unit 830 will not be used to sense touch behavior during the display phase. In some embodiments, in the normal mode (for example: before entering the anti-peeping mode or after releasing the anti-peeping area), the control circuit 860 can enable the touch sensing path during the touch sensing phase so that the sensing unit 830 is used to sense touch behavior.

[0175] Fig. 9 1 is a schematic diagram of an electronic device 100C including a display unit according to some embodiments of the present invention. In some embodiments, the electronic device 100C may be used to implement the following Fig.10 The display method 1000 is shown to control the privacy protection area, but the present invention is not limited thereto. The electronic device 100C can be similar to the previously described Figure 1 In the electronic device 100 , the same reference symbols represent the same or similar elements, and thus they are not described in detail herein.

[0176] Reference Fig. 9, the electronic device 100C includes a display unit 102, a processing unit 107, and a light control unit 108. The display unit 102 is used to display an image, and may include a panel 104 and a first control circuit 110. The display unit 102 may include a self-luminous display unit and a non-self-luminous display unit. The processing unit 107 is electrically connected to the display unit 102, and may include a processing device 170. The light control unit 108 is electrically connected to the processing unit 107, and may include a second control circuit 130. In some embodiments, the light control unit 108 may include one or more of an anti-peeping unit, an anti-peeping light output array, an anti-peeping light output module, or an anti-peeping film, but the present invention is not limited thereto. In some embodiments, the anti-peeping unit, the anti-peeping light output array, the anti-peeping light output module, or the anti-peeping film may be controlled by an anti-peeping unit driving circuit 136, an anti-peeping display driving circuit 137, or a backlight unit driving circuit 138. In some embodiments, the processing device 170 may be a processor of various computers, and / or may include or be coupled to a memory device, but the present invention is not limited thereto.

[0177] The processing unit 107 of the electronic device 100C may include or be electrically connected to an input device (e.g., a touch sensor 180). In some embodiments, a user may activate the anti-peeping function by means of a touch sensor 180 connected to the processing device 170, but the present invention is not limited thereto. In other embodiments, a user may activate the anti-peeping function by means of other suitable input means such as a mouse or a keyboard. After activating the anti-peeping function, the processing device 170 may transmit predefined information of the anti-peeping window (e.g., stored in a memory device) to the microcontroller unit 140. Then, the microcontroller unit 140 transmits the information of the anti-peeping window to the first control circuit 110 of the display unit 102. After the information of the anti-peeping window is calculated by the algorithm 114, anti-peeping data including the anti-peeping window will be generated. The multiplexer 120 selects the anti-peeping data generated by the algorithm 114 and outputs the anti-peeping data to the second control circuit 130 of the light control unit 108.

[0178] After receiving the anti-peeping data, the second control circuit 130 outputs the timing and data to the anti-peeping unit driving circuit 136, the anti-peeping display driving circuit 137 or the backlight unit driving circuit 138 according to the anti-peeping data, so as to control the light emission pattern of the anti-peeping unit, the anti-peeping light array or the anti-peeping light module under a certain viewing angle. By controlling the light emission pattern of the anti-peeping unit, the anti-peeping light array or the anti-peeping light module in the window to be protected from peeping, the window to be protected from peeping can be made to enter the anti-peeping mode and become an anti-peeping window.

[0179] In some embodiments, the anti-peeping mode of the anti-peeping window can be released by the following method. A switching control signal can be sent by the microcontroller unit 140 to enable the multiplexer 120 to select the graphics output by the graphic generator 118 to the second control circuit 130. Then, the anti-peeping unit, the anti-peeping light output array or the anti-peeping light output module driven by the second control circuit 130 will stop limiting the light output light type, so that the anti-peeping window releases the anti-peeping mode. In this way, the entire display unit will enter the non-peeping mode. It should be noted that the above method is only an example of releasing the anti-peeping mode of the anti-peeping window, and the present invention is not limited to this. The anti-peeping mode of the anti-peeping window can be released by any suitable method.

[0180] Fig.10 1 is a flow chart of a method 1000 for controlling a display of an anti-peeping window according to an embodiment of the present invention. FIG. 11A to FIG. 11C According to an embodiment of the present invention, Fig.10 A simplified schematic diagram of an embodiment of the display method 1000 is shown. It should be noted that Fig.10 and FIG. 11A to FIG. 11C The order of operations shown in the figure is only an example, and the order of operations is not limited to Fig.10 and FIG. 11A to FIG. 11C The following will also refer to Fig.10 and FIG. 11A to FIG. 11C The display method 1000 is described.

[0181] exist Fig.10 In operation 1102, the anti-peeping function is activated. In some embodiments, the user can activate the anti-peeping function by clicking an icon of an application on the touch display. Fig.11A As shown, the user can activate the anti-peeping function by clicking the icon 1110 of the application on the touch display 1100 of the electronic device. In other embodiments, the user can activate the anti-peeping function by voice, gesture, options on the display, mouse cursor, keyboard key combination, etc., but the present invention is not limited thereto, and the user can use any suitable input means to activate the anti-peeping function.

[0182] exist Fig.10 In operation 1004, a predefined window to be prevented from peeping is displayed. In some embodiments, a user can predefine a predefined anti-peeping requirement in a processing device according to his / her own anti-peeping requirement to predefine a desired window to be prevented from peeping, and after the anti-peeping function is activated, the display device displays the window to be prevented from peeping. For example, after the anti-peeping function is activated, the touch display 1100 displays the window to be prevented from peeping 1120 predefined by the user, such as Fig. 11B In some embodiments, the electronic device may display the anti-peeping window 1120 as a dotted line on the touch display 1100, such as Fig. 11BIn other embodiments, the touch display 1100 may display the window 1120 to be protected from peeping in solid lines, grayscale, etc., but the present invention is not limited thereto. It should be noted that the anti-peeping window and the window to be protected from peeping may also be referred to as the anti-peeping area and the area to be protected from peeping in this document.

[0183] exist Fig.10 In operation 1006, it is confirmed whether the window to be protected from peeping that is about to enter the anti-peeping mode meets the requirements. In some embodiments, the electronic device may display a dialog box on the display to ask the user whether the currently displayed window to be protected from peeping meets the requirements. For example, the electronic device may display a dialog box 1130 on the touch display 1100 to ask the user whether the window to be protected from peeping 1120 meets the requirements, such as Fig. 11B In some embodiments, operation 1004 and operation 1006 may be performed in combination.

[0184] In some embodiments, the window to be protected from peeping may be a window of an application, such as an office series application or a web browser. In some embodiments, the window to be protected from peeping may be a predefined area. For example, for a car display, the window to be protected from peeping may be the area in front of the co-pilot and / or the center information display (CID), but the present invention is not limited thereto. For example, for an ATM or an interactive multimedia information station, the window to be protected from peeping may be the area for inputting a password, but the present invention is not limited thereto.

[0185] In some embodiments, the window to be protected from peeping can be predefined by inputting a keyword. When the electronic device detects the predefined keyword, the window associated with the keyword can be used as the window to be protected from peeping. For example, the keyword used for the window to be protected from peeping can include an account, password, payment information, confidential customer information, etc., but the present invention is not limited thereto, and the user can input any keyword according to his or her own anti-peeping needs.

[0186] In some embodiments, the window to be prevented from peeping may be pre-defined in the application, and / or the user may manually input keywords for pre-definition, but the present invention is not limited thereto. In some embodiments, the pre-definition of the window to be prevented from peeping may be executed in a processing device or a computer, and the information of the window to be prevented from peeping may be stored in a memory device, but the present invention is not limited thereto. Then, when the anti-peeping function is activated, the window to be prevented from peeping may be displayed according to the pre-defined window to be prevented from peeping.

[0187] When the user confirms that the window to be protected from peeping meets the requirement (for example, by touching or clicking the mouse Fig. 11B In the dialog box 1130, the method 1000 is displayed and proceeds to operation 1008. Fig.10In operation 1008, the light pattern of the peep-proof window is limited. In some embodiments, the electronic device limits the light pattern of the peep-proof window that is about to enter the peep-proof mode, so that the peep-proof window enters the peep-proof mode and becomes the peep-proof window. For example, the electronic device limits the light pattern of the peep-proof window 1120 of the touch display 1100, so that the peep-proof window 1120 enters the peep-proof mode and becomes the peep-proof window 1140. Fig. 11C shown.

[0188] When the user confirms that the window to be protected from peeping does not meet the requirements (for example, by touching or clicking the mouse Fig. 11B If the user selects "No" in the dialog box 1130, the method 1000 proceeds to operation 1010. Fig.10 In operation 1010, the window to be protected from peeping is redefined. Operation 1010 can reselect the window to be protected from peeping according to the predefined window to be protected from peeping. After operation 1010, the display method 1000 enters operation 1006 again.

[0189] In some embodiments, the anti-peeping function can be automatically activated when a keyword is detected. In some embodiments, the window to be protected from peeping can be automatically made to enter the anti-peeping mode and become the anti-peeping window when a keyword is detected. In some embodiments, the display method 1000 can be implemented in software, and the electronic device can enable the anti-peeping function via the software, but the present invention is not limited thereto.

[0190] exist FIG. 11A to FIG. 11C In the example shown, FIG. 11A to FIG. 11B It is a non-privacy mode (or normal mode) that has not yet entered the privacy mode. Fig. 11C This is an anti-peeping mode, but the present invention is not limited thereto. Fig. 11B In the example shown, the window 1120 to be protected from peeping can enter the peeping mode while the dialog box 1130 is displayed.

[0191] FIG. 12A to FIG. 12B According to the embodiment of the present invention, the following reference Fig.13 A simplified schematic diagram of one embodiment of a display method 1300 is shown. Fig.13 1 is a flow chart of a method 1300 for controlling a display of an anti-peeping window according to an embodiment of the present invention. FIG. 12A to FIG. 12B as well as Fig.13 The display method 1300 is described.

[0192] exist Fig.13 In operation 1302, the anti-peeping function and dynamic anti-peeping are activated. In some embodiments, the user can activate the anti-peeping function and dynamic anti-peeping by clicking the icon of the application on the touch display. Fig. 12AAs shown, the user can activate the anti-peeping function and dynamic anti-peeping by clicking the icon 1210 of the application on the touch display 1200 of the electronic device. In other embodiments, the user can activate the anti-peeping function and dynamic anti-peeping by voice, gesture, options on the display, mouse cursor, keyboard key combination, etc., but the present invention is not limited thereto, and the user can use any suitable input means to activate the anti-peeping function and dynamic anti-peeping.

[0193] After operation 1302, the display method 1300 may determine the privacy protection area to enter the privacy protection mode by a method similar to the display method 200 and the display method 1000. For example, the display method 1300 may determine the privacy protection area (e.g., privacy protection area 350) to enter the privacy protection mode by operation 204, operation 206, and operation 210 of the display method 200, such as Fig.13 Alternatively, the display method 1300 may determine the anti-peeping area (eg, the anti-peeping window 1140) to enter the anti-peeping mode through operations 1004, 1006, and 1010 of the display method 1000, as shown in FIG. Fig.13 It should be noted that, in order to simplify the description, this article refers to FIG. 12A to FIG. 12B as well as Fig.13 The anti-peep window is also referred to as an anti-peep area in the description.

[0194] Reference Fig.13 After determining the privacy protection area in operation 206 or operation 1006, the display method 1300 enters operation 1304. In operation 1304, the electronic device performs eye tracking through an optical sensor to sense the position of the user's eyes. For example, eye tracking can be performed through an optical sensor 1220 on the touch display 1200 to sense the position of the user's eyes, such as Fig. 12A In some embodiments, the optical sensor 1220 may be a camera, a charge coupled device, an infrared (IR) sensor, etc., but the present invention is not limited thereto.

[0195] exist Fig.13 In operation 1306, the electronic device calculates at least two viewing angles of each point in the privacy protection area on the display relative to the user's eyes. Fig.13In operation 1308, the light control unit of the electronic device (for example, light control unit 108) adjusts the light type required by the display according to the viewing angle calculated in operation 1306, so that the light in the anti-peeping area is sent toward the user's eyes, so that the light intensity is concentrated in at least two viewing angles of the user's eyes. In this way, only the area where the user is located can clearly see the content displayed on the display, regardless of whether the user is directly in front of the display. On the other hand, other people whose positions and viewing angles are different from the user cannot see the content displayed on the display. For example, the light control unit of the electronic device controls the light output type in the anti-peeping area 1230, so that the anti-peeping area 1230 enters the anti-peeping mode, such as Fig. 12B As shown. Fig. 12B In the illustrated embodiment, the light control unit sends the light in the privacy protection area 1230 toward the user's eyes, so that people other than the user cannot see the content displayed on the touch display 1200, thereby putting the privacy protection area 1230 into privacy protection mode.

[0196] After operation 1308, method 1300 will enter operation 1304 again and repeat the sequence of operation 1304, operation 1306 and operation 1308. Therefore, method 1300 can continuously adjust the light type required by the display as the position of the user's eyes changes, so that the light in the privacy protection area is sent toward the user's eyes. In this way, no matter how the user changes his position and / or posture, the user can clearly see the content displayed on the display, and the privacy protection function is still effective.

[0197] Fig.14 1 is a schematic diagram of an anti-peeping display 1400 according to an embodiment of the present invention. Fig.14 The anti-peeping display 1400 includes a backlight unit 1410, an anti-peeping unit 1420, a display panel 1430, and a touch sensor 1440. In some embodiments, the display panel 1430 may be disposed above the anti-peeping unit 1420, such as Fig.14As shown, but the present invention is not limited thereto. In other embodiments, the display panel 1430 may be disposed between the anti-peeping unit 1420 and the backlight unit 1410. In some embodiments, the anti-peeping unit 1420 includes a substrate 1421, an active anti-peeping electrode layer 1422 above the substrate 1421, a liquid crystal layer 1423 above the active anti-peeping electrode layer 1422, a common electrode layer 1424 above the liquid crystal layer 1423, and a substrate 1425 above the common electrode layer 1424. In some embodiments, the anti-peeping unit 1420 may be part of a light control unit of an electronic device. In some embodiments, the anti-peeping display may further include two other anti-peeping units (not shown), and the three anti-peeping units are disposed between the backlight unit 1410 and the display panel 1430. In addition, the backlight unit 1410 may further include one or more optical films, and the optical film may include, for example, a brightness enhancement film (BEF) and a light control film (LCF), but is not limited thereto. In some embodiments, the light control film may be disposed between the brightness enhancement film and the privacy protection unit, but is not limited thereto.

[0198] In some embodiments, the light emitted by the backlight unit 1410 is collimated light. In some embodiments, the driving circuit of the anti-peeping display 1400 or the anti-peeping unit 1420 can drive the active anti-peeping electrode layer 1422 and the common electrode layer 1424 to control the arrangement of liquid crystal molecules in the liquid crystal layer 1423 between the active anti-peeping electrode layer 1422 and the common electrode layer 1424. In the anti-peeping mode, the arrangement of liquid crystal molecules in the portion of the liquid crystal layer 1423 corresponding to the anti-peeping area can be controlled so that the collimated light emitted by the backlight unit 1410 will not diverge when passing through the liquid crystal layer 1423. In this way, the light emission pattern of the anti-peeping area will be limited to a certain angle, thereby achieving an anti-peeping effect. In the non-anti-peeping mode or in the non-anti-peeping area, the arrangement of liquid crystal molecules in the portion of the liquid crystal layer 1423 corresponding to the anti-peeping area can be controlled so that the collimated light emitted by the backlight unit 1410 diverges when passing through the liquid crystal layer 1423. Thereby, the viewing angle in the non-privacy area or in the non-privacy mode can be increased.

[0199] In some embodiments, the display panel 1430 may be a self-luminous panel. In these embodiments, the display panel 1430 may be disposed below the privacy protection unit, and the backlight unit 1410 may be omitted.

Fig.16 , the anti-peeping display 1600 includes an anti-peeping light array 1610 and a display panel 1640 above the anti-peeping light array 1610. In some embodiments, the anti-peeping light array 1610 includes a light-emitting diode array 1620 and a lens array 1630 above the light-emitting diode array 1620. In some embodiments, the light-emitting diodes 1625 in the light-emitting diode array 1620 may be OLED, mini LED, micro LED or QDLED, but the present invention is not limited thereto. In some embodiments, the lenses in the lens array 1630 may be convex lenses, but the present invention is not limited thereto. In some embodiments, the lens array 1630 may be a one-dimensional array or a two-dimensional array. In some embodiments, the display panel 1640 includes a color filter layer 1645, but the present invention is not limited thereto.

In some embodiments, the anti-peeping display 1600 is a non-self-luminous display, in which the light-emitting diode array 1620 is a backlight unit or a part thereof. In some embodiments, the anti-peeping light array 1610 may be a part of a light control unit of an electronic device.

[0202] In some embodiments, the driving circuit of the anti-peeping display 1600 or the LED array 1620 can drive the LED array 1620 to control the opening (brightness) or closing (darkness) of the LEDs 1625 in the LED array 1620. In the anti-peeping mode, the light emission pattern of the anti-peeping area can be controlled by turning on specific LEDs 1625. For example, the LED 1625A located near the focus of the lens of the lens array 1630 can be turned on and the other LEDs 1625B can be turned off, so that the light emitted by the LED array 1620 becomes collimated light after passing through the lens array 1630. In this way, the light emission pattern of the anti-peeping area will be limited to a certain angle, thereby achieving an anti-peeping effect. Similarly, in some embodiments, the other LEDs 1625 other than the LED 1625A can be turned on so that the light emitted by the LED array 1620 is concentrated at a specific angle after passing through the lens array 1630. In this way, the light pattern of the anti-peeping area will be limited and can be freely adjusted as the user's eye position changes, thereby achieving a dynamic anti-peeping effect. In other words, the light pattern of the anti-peeping area can be adjusted according to the change of the user's viewing angle to achieve a dynamic anti-peeping effect. In the non-peeping mode or in the non-peeping area, the light-emitting diodes 1625 in the light-emitting diode array 1620 can be fully turned on or partially turned on in a uniformly distributed manner. In this way, the viewing angle in the non-peeping area or in the non-peeping mode can be increased.

[0203] Fig.17 1 is a schematic diagram of an anti-peeping display 1700 according to an embodiment of the present invention. Fig.17 , the anti-peeping display 1700 includes an anti-peeping light output array 1710 and a display panel 1750 above the anti-peeping light output array 1710. In some embodiments, the anti-peeping light output array 1710 includes a backlight unit 1720, a monomer unit (mono cell) array 1730 above the backlight unit 1720, and a lens array 1740 above the monomer unit array 1730. In some embodiments, the monomer unit 1735 in the monomer unit array 1730 may include a liquid crystal material, but the present invention is not limited to this. In some embodiments, the lens in the lens array 1740 may be a convex lens, but the present invention is not limited to this. In some embodiments, the lens array 1740 may be a one-dimensional array or a two-dimensional array. In some embodiments, the display panel 1750 includes a color filter layer 1755, but the present invention is not limited to this. In some embodiments, the anti-peeping light output array 1710 may be part of a light control unit of an electronic device.

[0204] In some embodiments, the driving circuit of the anti-peeping display 1700 can drive the arrangement of liquid crystal molecules in the monomer unit 1735 of the monomer unit array 1730 to control whether the monomer unit 1735 allows the light from the backlight unit 1720 to pass through. In the anti-peeping mode, the light emission pattern of the anti-peeping area can be controlled by allowing a specific monomer unit 1735 to allow the light from the backlight unit 1720 to pass through. For example, the monomer unit 1735A located near the focus of the lens of the lens array 1740 can allow light to pass through and the other monomer units 1735B can not allow light to pass through, so that the light emitted by the backlight unit 1720 becomes collimated light after passing through the monomer unit array 1730 and the lens array 1740. In this way, the light emission pattern of the anti-peeping area will be limited to a certain angle, thereby achieving an anti-peeping effect. Similarly, in some embodiments, other monomer units 1735 other than monomer unit 1735A can allow light to pass through, so that the light emitted by the backlight unit 1720 is concentrated at a specific angle after passing through the monomer unit array 1730 and the lens array 1740. In this way, the light output pattern of the anti-peeping area will be limited and can be freely adjusted as the position of the user's eyes changes, thereby achieving a dynamic anti-peeping effect. In other words, the light output pattern of the anti-peeping area can be adjusted according to the change of the user's viewing angle to achieve a dynamic anti-peeping effect. In non-peeping mode or in non-peeping area, the monomer units 1735 in the monomer unit array 1730 can be all turned on or partially turned on in a uniformly distributed manner. In this way, the viewing angle in the non-peeping area or in non-peeping mode can be increased.
