[0036] To enable those skilled in the art to better understand the solution of the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field of the present utility model. The terms used in the specification of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0037] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present utility model. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0038] On the one hand, referring to Figures 1 to 4 , an embodiment of the present utility model provides a segmented display screen, including: dot matrix display areas 10, 10a and a driving circuit 40. A plurality of the dot matrix display areas 10, 10a are respectively provided, and the plurality of dot matrix display areas 10, 10a are arranged in sequence; as Figure 1 shown, the display screen includes a plurality of dot matrix display areas 10, 10a. A display screen is formed by a plurality of dot matrix display areas 10, 10a. The driving circuit 40 is respectively connected to the dot matrix display areas to drive each of the dot matrix display areas 10, 10a to display information. Each dot matrix display area 10, 10a can be driven for display through the driving circuit 40. In this way, each display area can display information under the drive of the driving circuit 40. The display information can include any one or more of control icons, text, or digital information display. Since the display screen is formed by arranging a plurality of the dot matrix display areas 10, 10a in sequence to form a segmented display screen. In this way, when driving the display screen, each of the dot matrix display areas 10, 10a can be driven separately. Compared with the prior art in which the driving circuit 40 drives the LCD display screen as a whole display dot matrix, this segmented display screen has relatively lower power consumption, lower driving requirements, and correspondingly lower costs, and can meet the application requirements of low power consumption and low cost for electronic input devices such as keyboards.

[0039] Referring to Figure 1 , the segmented display screen further includes: non-display areas 20, 20a. One or more non-display areas 20, 20a are provided, and the dot matrix display areas 10, 10a and the non-display areas 20, 20a are arranged crosswise. As Figure 1As shown, a plurality of the display areas and the non-display areas 20, 20a are arranged crosswise along the length extension direction of the display screen. As Figure 1 As shown, the segmented display screen can be in the shape of a long strip. The non-display areas 20, 20a and the dot matrix display areas 10, 10a can be distributed at intervals and crosswise. In this way, there can be a certain distance between the two dot matrix display areas 10, 10a. One of the dot matrix display areas 10, 10a can be used to display a specific piece of information. By separating the two adjacent dot matrix display areas 10, 10a through the non-display areas 20, 20a, the information displayed in each dot matrix display area 10, 10a can be made clearer, avoiding mutual influence and confusion. Since the non-display areas 20, 20a do not need to be driven and do not display information, the driving requirements can be low, more energy-saving, and the production cost of the overall display screen can be lower.

[0040] As Figures 1 to 3 As shown, the segmented display screen in the shape of a long strip can be made in different sizes according to application requirements to meet the application requirements. Of course, it should be noted that in other embodiments, the segmented display screen can also be in other shapes, rather than in the shape of a long strip.

[0041] Furthermore, in an embodiment of the present invention, the driving circuit 40 is further used to communicate with an electronic device to receive a display information change signal of the electronic device, and modify the display information of the corresponding dot matrix display areas 10, 10a according to the display information change signal. Specifically, sometimes it may be necessary to change the icons, numbers, or characters to be displayed in each dot matrix display area 10, 10a to meet different application scenarios or requirements. By communicating with the electronic device, the driving circuit 40 can receive the information change signal sent by the electronic device and modify the display information of the corresponding dot matrix display areas 10, 10a according to the display information change signal. For example, when it is necessary to change the icon, text, or number of a certain dot matrix display area 10, 10a to another icon, text, or number, the electronic device can transmit the relevant change information to the driving circuit 40, and the driving circuit 40 can replace the icon, text, or number of the corresponding dot matrix display area 10, 10a with a new icon, text, or number.

[0042] Refer to Figure 4, Further, in an embodiment of the present invention, the segmented display screen further includes: a touch layer, which is used to obtain touch information of the dot matrix display areas 10, 10a and / or the non-display areas 20, 20a, and output the touch information to an electronic device to perform operation control on the electronic device. To increase the touch function, a touch layer can be added above, below, or inside the dot matrix display areas 10, 10a and / or the non-display areas 20, 20a. In this way, touch on the electronic device is realized. As Figure 4 shown in, touch areas 50, 50a are formed between the dot matrix display area and some or all of the non-display areas on both sides, and the touch areas 50, 50a are used to obtain the touch information. Non-touch areas 60, 60a are formed between the two touch areas 50, 50a. When a user needs to operate the electronic device, the finger can be placed on the corresponding touch area 50, 50a. In this way, the corresponding touch information can be obtained through the touch areas 50, 50a and output to the electronic device to perform operation control on the electronic device. For example, in an embodiment of the present invention, when the information display includes volume control information, the touch information includes information for adjusting the volume of the electronic device. For example, the adjacent two dot matrix display areas 10, 10a can respectively display a volume increase symbol "Volume +" and a volume decrease symbol "Volume -". When a user needs to adjust the volume on the electronic device, the symbol display area of "Volume +" or "Volume -" can be touched. In this way, when the finger is placed on the corresponding touch area of the volume adjustment display symbol, the touch layer can obtain the corresponding touch information and output it to the electronic device. In this way, the electronic device can adjust the volume. Of course, in some other embodiments of the present invention, other touch functions can also be added through the touch layer, not limited to only adjusting the volume.

[0043] Further, in an embodiment of the present invention, the dot matrix display areas 10, 10a are liquid crystal LCD dot matrices and / or light emitting diode LED dot matrices. That is, the dot matrix display areas 10, 10a can be realized by using liquid crystal LCD dot matrix technology, or can be realized by using light emitting diode LED dot matrix technology. Of course, in some embodiments, a combination of the two technologies can also be used. For example, a liquid crystal LCD dot matrix is combined with a segment display tube to form a dot matrix display area 10, 10a. When realized by using liquid crystal LCD dot matrix technology, the segmented display screen further includes a backlight board, and the dot matrix display area is a liquid crystal dot matrix; the backlight board is used to provide a backlight source for the liquid crystal dot matrix. In this way, under the control of the driving circuit, the display information can be displayed.

[0044] On the other hand, an embodiment of the present utility model further provides an input device, including: an input device main body and the above-mentioned segmented display screen, and the segmented display screen is arranged on the input device main body. Among them, the input device can be an independent keyboard or an integrated notebook keyboard, etc. The segmented display screen can be installed above the keyboard and other positions. In this way, it is convenient for users to obtain corresponding information through the segmented display screen when using an input device such as a keyboard for information input. The corresponding information can include control icons, text, numbers, etc. Among them, each dot matrix display area 10, 10a on the segmented display screen can display information such as control icons, text, or numbers. In this way, when the user uses the keyboard for information input, the corresponding information can be obtained through the segmented display screen. And through this kind of segmented display screen, the power consumption can be relatively small, the driving requirement is lower, and the cost is also correspondingly smaller, which can meet the application requirements of low power consumption and low cost for electronic input devices such as keyboards.

[0045] Further, in an embodiment of the present utility model, a control circuit board is provided inside the input device, and the segmented display screen is communicatively connected to the control circuit board through a cable 30, where the cable 30 can be a flexible printed circuit board FPC. As Figure 1 shown, the segmented display screen is communicatively connected to the control circuit board of the keyboard. In this way, communication can be carried out with the electronic device through the control circuit board of the keyboard, so as to receive the display information change signal output by the electronic device and change the display information. At the same time, when a touch layer is provided on the display screen, the electronic device can be controlled through the touch layer and the control circuit board.
