The screen image control device, method, and terminal device can be applied to electronic photo frames, shopping mall guide desktop screens, shopping guide tablets, etc. In this embodiment, an electronic photo frame is used as an example for illustration.

[0035] Embodiment 1:

[0036] Figure 1 is a schematic diagram of the structure of the screen image control device according to an embodiment of the present application, Figure 2 It is a schematic diagram of the structure of the touch bar in the screen control device described in an embodiment of the present application.

[0037] like Figure 1 and Figure 2 As shown, an embodiment of the present application provides a device for controlling a screen image, including a touch control body 10 and a touch bar 20 disposed on the touch control body 10 .

[0038] In the embodiment of the present application, the touch control body 10 is used to display images; the touch control body 10 includes a display frame 11 and a display screen 12 embedded in the display frame 11 .

[0039] It should be noted that the touch body 10 refers to a terminal device that can display a picture. In this embodiment, the touch body 10 may refer to an electronic photo frame. Since the electronic photo frame is a display item, a display screen with a touch function such as a tablet is generally not provided in the electronic photo frame, which will increase the production cost of the electronic photo frame and have no market; therefore, a touch bar 20 is separately mounted on the touch body 10 of this embodiment, and the display screen of the touch body 10 is controlled by the touch bar 20, eliminating the dependence on the touch screen. Then the display screen 12 can use an ordinary display screen, which reduces the production cost of the control device of the screen picture and improves the market competitiveness. Among them, the touch bar 20 can be installed at any position of the upper, lower, left, and right of the display frame 11 according to the needs.

[0040] In the embodiment of the present application, the touch bar 20 is built into the display frame 11. The touch bar 20 is provided with a touch IC and a plurality of trigger elements arranged in a matrix, and each trigger element is connected to the touch IC to form a trigger channel. The trigger element is used to generate point position information according to the touch operation performed by the user on the touch sub-sensing area corresponding to the trigger element, and upload the point position information to the touch IC through the trigger channel corresponding to the trigger element; the sensitivity of the touch IC is adjusted according to the dielectric constant of the material of the display frame 11.

[0041] It should be noted that the touch bar 20 only supports sliding in a single coordinate axis direction. The trigger element uploads charge information to the touch IC through the trigger channel to obtain the reporting point position information. The touch IC uses I2C communication to transmit the reporting point position information in the form of digital signals to the main control IC of the display screen 12. The data exchange between the main control IC and the display screen 12 is realized by MIPI communication. In this embodiment, Figure 2As shown in the figure below, the design of the touch bar is as follows. 16 trigger elements are evenly arranged on the touch bar 20, and these trigger elements are connected to the trigger channel of the touch IC. The trigger channel can keenly sense the charge change. When the user's finger slides and clicks on the touch bar 20, the trigger element 21 will sense the charge change caused by the finger sliding or clicking, and report the point position information to the touch IC through the corresponding trigger channel, and execute the corresponding response on the display screen 12 to complete the touch function. In this embodiment, the control device of the screen image is installed on the top of the touch body 10 with a 100mm*8mm touch bar 20, and the shell surface mapped by the touch bar 20 is smoothed to reflect the touch range. By providing a plurality of trigger elements on the touch bar 20, the user's hand will report the point position information to the touch IC after touching or sliding on the sensing area of ​​the touch bar 20. The point position information data is transmitted to the touch IC through I2C (inter-integrated Circuit; a serial communication bus standard) for analysis and processing. After receiving the corresponding signal, the touch IC controls the display screen 12 to perform corresponding functions or screen switching and display, thereby breaking away from the role of traditional touch screens and reducing product costs.

[0042] In the embodiment of the present application, the touch control IC is connected to the main control IC of the display screen 12 , and the main control IC is used to control the display screen 12 according to the reporting point position information.

[0043] It should be noted that the touch IC can identify the reporting point position information based on the double-click and sliding behaviors on the touch IC of the touch bar 20, and transmit the operation instructions of the identified behaviors to the main control IC of the display screen 12. The main control IC will process these operation instructions to obtain control signals, and perform corresponding operations on the currently displayed interface according to the control signals, such as: dragging to adjust the video progress, pausing playback, etc. The main control IC can convert the reporting point position information identified by the touch IC into the corresponding function. After the touch bar 20 transmits the operation instructions identified according to the reporting point position information to the main control IC through I2C communication, the main control IC will parse the operation instructions expressed in the form of digital signals transmitted by the I2C communication to obtain control signals, and then implement the corresponding operations through MIPI communication according to the control signals.

[0044] Because the touch bar 20 is not directly exposed to the outside and in direct contact with the user's fingers but is embedded in the shell, the user's fingers are separated from the touch bar 20 by a layer of contact medium. Since different materials have different dielectric constants, the touch bar 20 will have different charge sensing sensitivities to the user's fingers. In order to achieve the best touch effect, it is necessary to control the material and thickness of the shell for matching. In the embodiment of the present application, the sensitivity of the touch IC is adjusted according to the dielectric constant of the material of the display frame 11. Because the dielectric constant affects the touch sensitivity, the larger the dielectric constant of the material, the easier it is to polarize in the electric field and the more effectively it can change the capacitance. The rule for adjusting the sensitivity of the touch IC according to the dielectric constant of the material of the display frame 11 is: the material with a larger dielectric constant can lower the sensitivity of the touch IC to the charge, and vice versa, the sensitivity of the touch IC to the charge should be increased.

[0045] It should be noted that the control device of the screen image can set the sensitivity of the touch IC according to the dielectric constant of the material of the display frame 11, so that the touch sensitivity of the control device of the screen image will also change with the material of the display frame 11 to meet the touch sensitivity requirements of different materials to achieve a touch effect.

[0046] The present application provides a screen image control device, including a touch body and a touch bar, wherein the touch body includes a display frame and a display screen embedded in the display frame; the touch bar is built into the display frame, and a touch IC and a plurality of trigger elements arranged in a matrix are arranged on the touch bar, and each trigger element is connected to the touch IC to form a trigger channel; the trigger element is used to generate point position information according to the touch operation performed by the user and the touch sub-sensing area corresponding to the trigger element, and upload the point position information to the touch IC through the trigger channel corresponding to the trigger element; the sensitivity of the touch IC is adjusted according to the dielectric constant of the material of the display frame. The screen image control device realizes the image control of the touch body display screen by carrying a touch bar on the display frame of the touch body, replacing the touch function of traditional buttons and touch screens, reducing product costs, and improving market competitiveness; it solves the technical problem that the existing touch technology is applied to low-intelligence and low-integration products, with high costs and weak market competitiveness.

[0047] It should be noted that the control device of the screen image abandons the touch function of the traditional touch screen on the market. It is optimized according to the touch pad on the existing notebook to make a specific touch bar 20 combined with the display frame 11 of the touch body 10, forming a new electronic device controlled by a touch sliding touch bar. The user operates by touching the touch bar, achieving the same intuitive and convenient operation method as the touch screen, realizing the original function of the product, reducing product costs, and improving market competitiveness.

[0048] Compared with the button control on current TV products, the problem of frequently pressing the wrong button will appear on the back of the display, and the large number of buttons makes operation inconvenient. The screen control device solves this problem. The control of the screen control device is simple. Double-clicking any area of ​​the touch bar 20 can enter the function option interface, and sliding can realize left and right functions.

[0049] Preferably, no matter how big the screen is, the control device of the screen image can be realized by a small touch bar 20, which has strong applicability. If the traditional touch screen solution is used, the larger the screen size, the higher the cost of the touch function, so there are almost no large-screen touch display devices on the market. Often, a mouse or other peripheral is required for control, but for example, a wall-mounted screen cannot be controlled by an external mouse or there is no environment to realize external mouse control, so the control device of the screen image is the best solution.

[0050] like Figure 2 As shown, in one embodiment of the present application, corresponding to the touch IC and the trigger element, the touch bar 20 is divided into a hardware setting area 24 and a sensing area 23, the hardware setting area 24 is used to carry the touch IC; the sensing area 23 is provided with a touch sub-sensing area 221 corresponding to each trigger element.

[0051] It should be noted that the distance between two adjacent touch sub-sensing areas 221 can be selected to be 0.2 mm to 0.5 mm. The shape of the touch sub-sensing area 221 can be square, rectangular, circular or elliptical, etc.; the shape of the touch sub-sensing area 221 can also be set to other shapes according to requirements. In this embodiment, Figure 2 As shown, the interval between two adjacent touch sub-sensing areas 221 in the control device of the screen image is 0.2mm~0.5mm, and each touch sub-sensing area 221 is connected to the trigger channel corresponding to the touch IC, and these trigger channels can keenly sense the charge change. In the hardware setting area, not only the touch IC can be placed, but also other electronic devices of the touch bar 20 can be placed. The hardware setting area 24 and the sensing area 23 are placed on different surfaces. The touch sub-sensing area 221 of the touch area in a matrix is ​​attached to the display frame 11 to avoid structural interference between the touch bar 20 and the structural surface of the display frame 12.

[0052] In one embodiment of the present application, a mounting groove for mounting the touch bar 20 is provided on the display frame 11 .

[0053] It should be noted that the installation groove is provided to facilitate the installation of the touch bar 20. In this embodiment, the touch bar 20 and the installation groove can be installed by bonding, welding or embedding.

[0054] Embodiment 2:

[0055] Figure 3Schematic diagram of the steps of the screen image control method described in an embodiment of the present application.

[0056] like Figure 3 As shown, an embodiment of the present application provides a screen image control method, which is applied to the screen image control device described above, and the control method includes the following steps:

[0057] S1. Obtaining the position information of the reported point when the user performs a touch operation in the sensing area of ​​the touch bar.

[0058] It should be noted that the contents of the screen control device have been described in the first embodiment, and will not be repeated in this embodiment. In step S1, the position information of the point reported by the user on the touch bar in real time is obtained to provide information for the subsequent control of the touch body.

[0059] In an embodiment of the present application, before obtaining the position information of the touch point reported by the user in the touch sub-sensing area, the control method includes: establishing a reference coordinate on the sensing area, and constructing coordinates for each touch sub-sensing area of ​​the sensing area according to the reference coordinates; wherein, in the touch IC, various instructions for controlling the display screen to operate are set according to the coordinates of each touch sub-sensing area and the coordinate changes of the sensing area.

[0060] It should be noted that the reported point position information refers to the position information of the current touch bar touched by the user's real-time touch operation, and the position information may include the click coordinates of the user's touch operation or the coordinate change value of the slide. In this embodiment, the touch bar 20 has 16 matrix touch sub-sensing areas corresponding to the trigger elements from left to right, for example: they are named No. 1, No. 2, ..., No. 16 in sequence, and are established based on the first trigger element. The coordinates of No. 1 are (1, 0), ..., the coordinates of No. 12 are (12, 0), ..., and the coordinates of No. 16 are (16, 0); when the touch operation slides from No. 1 to No. 2, the change will be recognized and the change in the position (the coordinate change value is 1 to 2) will be uploaded to realize the sliding function.

[0061] S2. Analyze the reported point location information to obtain a control signal.

[0062] It should be noted that in step S2, the control signal is obtained by analyzing the reported point position information in step S1 to provide data for step S3.

[0063] S3. According to the control signal, the display screen of the touch control body is controlled to perform function or screen switching and display operation corresponding to the reporting point position information.

[0064] It should be noted that step S3 is to control the operation of the display screen according to the control signal, so that the control device of the screen image realizes the image and function selection of the display screen through the touch bar through the control method of the screen image, thereby replacing the touch function of traditional buttons and touch screens, reducing product costs and improving market competitiveness.

[0065] In an embodiment of the present application, analyzing the reporting point position information to obtain a control signal includes: identifying the coordinates or coordinate change values ​​of the reporting point position information to obtain a corresponding operation instruction; and generating a corresponding control signal according to the operation instruction.

[0066] It should be noted that since the various instructions for controlling the operation of the display screen are set in the touch IC according to the coordinates of each touch sub-sensing area and the coordinate changes of the sensing area, the operation instructions for controlling the display screen can be identified according to the coordinates of the reported point position information or the coordinate change values, and then the operation instructions are generated into a control signal that can be used by the main control IC to control the operation of the display screen.
