[0036] In order to make those skilled in the art better understand the scheme of the present invention, the technical scheme in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0037] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0038] On the one hand, see Figures 1 to 4 The embodiment of the present invention provides a segmented touch display screen, comprising: a dot matrix display area 10, 10a and a driving circuit 40, wherein the dot matrix display area 10, 10a is provided with a plurality of dot matrix display areas 10, 10a, and the plurality of dot matrix display areas 10, 10a are arranged in sequence; Figure 1 As shown in , 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 connected to the dot matrix display areas respectively to drive each of the dot matrix display areas 10, 10a to display information. The driving circuit 40 can drive each dot matrix display area 10, 10a to display. In this way, each display area can display information under the drive of the driving circuit 40. The display information may include any one or more of control icons, text or digital information display. Since the display screen uses a plurality of dot matrix display areas 10, 10a arranged in sequence to form a segmented display screen. In this way, when the display screen is driven, each dot matrix display area 10, 10a can be driven separately. Compared with the prior art, in which the LCD display screen is driven as a whole display dot matrix by the driving circuit 40, this segmented touch display screen has relatively low power consumption, lower driving requirements, and correspondingly low cost, which can meet the application requirements of low power consumption and low cost for electronic input devices such as keyboards. Among them, more display modules can be arranged in the length direction, which may meet more diverse control and display needs.
[0039] See also Figure 1 The segmented touch screen also includes: a non-display area 20, 20a, wherein the non-display area 20, 20a is provided with one or more, and the dot matrix display area 10, 10a and the non-display area 20, 20a are arranged crosswise. Figure 1As shown in , the plurality of display areas and non-display areas 20, 20a are arranged crosswise along the length extension direction of the display screen. Figure 1 As shown in , the segmented touch 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 in an interlaced manner. 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 information. By separating two adjacent dot matrix display areas 10, 10a through the non-display areas 20, 20a, the information displayed by each dot matrix display area 10, 10a can be made clearer to avoid 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] like Figures 1 to 3 As shown in , the segmented touch display screen of the long strip shape can be made into different sizes according to the application needs to meet the application requirements. Of course, it should be noted that in other embodiments, the segmented touch display screen can also be other shapes instead of the long strip shape.
[0041] Further, in one embodiment of the present invention, the drive circuit 40 is also used to communicate with the electronic device to receive the display information change signal of the electronic device, and modify the display information of the corresponding dot matrix display area 10, 10a according to the display information change signal. Specifically, sometimes it may be necessary to change the icons, numbers or texts to be displayed in each dot matrix display area 10, 10a to meet different application scenarios or needs. The drive circuit 40 is connected to the electronic device through communication, so that it can receive the information change signal sent by the electronic device, and modify the display information of the corresponding dot matrix display area 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 drive circuit 40, and the drive 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] See also Figure 4Furthermore, in one embodiment of the present invention, the segmented touch display screen further includes: a touch layer, the touch layer is used to obtain touch information of the dot matrix display area 10, 10a and / or the non-display area 20, 20a, and output the touch information to the electronic device to operate and control the electronic device. In order to increase the touch function, a touch layer can be added above, below or inside the dot matrix display area 10, 10a and / or the non-display area 20, 20a. In this way, touch control of the electronic device is achieved. Figure 4 As shown in , a touch area 50, 50a is formed between the dot matrix display area and part of the non-display area or all of the non-display area on both sides, and the touch area 50, 50a is used to obtain the touch information. A non-touch area 60, 60a is formed between the two touch areas 50, 50a. When the 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 area 50, 50a, and the touch information can be output to the electronic device to operate and control the electronic device. For example, in one 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 volume increase symbol "volume +" and the volume decrease symbol "volume -" can be displayed respectively through the two adjacent dot matrix display areas 10, 10a. When the user needs to adjust the volume on the electronic device, the symbol display of "volume +" or "volume -" can be touched. In this way, when a 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 be added through the touch layer, and are not limited to the adjustment of the volume.
[0043] Furthermore, in one embodiment of the present invention, the dot matrix display area 10, 10a is a liquid crystal LCD dot matrix and / or a light emitting diode LED dot matrix. That is, the dot matrix display area 10, 10a can be implemented by using the liquid crystal LCD dot matrix technology, or by using the 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 code tube to form a dot matrix display area 10, 10a. When the liquid crystal LCD dot matrix technology is used, the segmented touch screen also includes a backlight panel, and the dot matrix display area is a liquid crystal dot matrix; the backlight panel is used to provide a backlight source for the liquid crystal dot matrix, so that the display information can be displayed under the control of the drive circuit.
[0044] On the other hand, an embodiment of the present invention further provides an input device, comprising: an input device body and the above-mentioned segmented touch display screen, wherein the segmented touch display screen is arranged on the input device body. The input device may be an independent keyboard or an integrated laptop keyboard, etc. The segmented touch display screen may be installed above the keyboard, etc. This facilitates the user to obtain corresponding information through the segmented touch display screen when using an input device such as a keyboard to input information. The corresponding information may include control icons, text or numbers, etc., wherein each dot matrix display area 10, 10a on the segmented touch display screen may display information such as control icons, text or numbers. In this way, when the user uses the keyboard to input information, the corresponding information can be obtained through the segmented touch display screen. And through this segmented touch display screen, the power consumption can be relatively small, the driving requirements are lower, and the cost is correspondingly small, which can meet the application requirements of electronic input devices such as keyboards that require low power consumption and low cost.
[0045] Furthermore, in one embodiment of the present invention, a control circuit board is provided in the input device, and the segmented touch display screen is connected to the control circuit board through a flat cable 30, wherein the flat cable 30 may be a flexible circuit board FPC. Figure 1 As shown in , the segmented touch display screen is connected to the control circuit board of the keyboard. In this way, the keyboard control circuit board can communicate with the electronic device, 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.
