Description

Technical Field

[0001] The present invention relates to the field of touch control technology, in particular to a low-cost touch color screen and a temperature controller using the same. Background Art

[0002] With the continuous advancement of technology and consumers' increasing pursuit of quality of life, the user interface (UI) interaction design of thermostats has begun to change from broken code screens to touch color screens. The application of touch color screens not only greatly improves the visual effect of thermostats, making their interfaces more vivid and intuitive, but also supports touch operations to enhance the user's interactive experience. The touch color screen includes a display area and a touch area. Since the display area usually displays UI controls for users to interact with the corresponding UI controls on the touch area, in the process of producing touch color screens, in order to enable the display area to display more UI controls, the display area is usually designed to be larger. However, this will increase the production cost of the display area, which may increase the production cost of the entire touch color screen. Summary of the invention

[0003] In view of the above-mentioned defects, the present invention proposes a low-cost touch color screen and a temperature controller using the same, aiming to solve the problem that in the existing process of producing touch color screens, in order to enable the display area to display more UI controls, the display area is usually designed to be larger, which increases the production cost of the display area and may increase the production cost of the entire touch color screen.

[0004] To achieve this object, the present invention adopts the following technical solutions:

[0005] A low-cost touch color screen comprises a display area and a touch area, wherein the touch area is located outside the display area;

[0006] The touch area includes a semi-transparent glass layer, a silk-screen layer, a touch layer and a backlight board layer. The semi-transparent glass layer, the silk-screen layer, the touch layer and the backlight board layer are arranged in sequence from top to bottom. The silk-screen layer is provided with icons of several UI controls, and the backlight board layer is provided with several LED lights. The icons of several UI controls correspond one to one with the several LED lights.

[0007] Preferably, the touch area further includes a touch driving circuit, and the touch driving circuit is electrically connected to the touch layer.

[0008] Preferably, the touch control area further includes a backlight driving circuit, and the backlight driving circuit is electrically connected to the backlight board layer.

[0009] Preferably, icons of several UI controls are unevenly distributed on the silk-screen layer.

[0010] Preferably, the LED lights on the backlight panel layer are RGB three-color LED lights.

[0011] Another aspect of the present application provides a thermostat using a low-cost touch color screen, including the low-cost touch color screen provided in the embodiment of the present application.

[0012] The technical solution provided by the embodiments of the present application may have the following beneficial effects:

[0013] This solution realizes the display effect of control icons in the area outside the display area by controlling the icons of UI controls on the silk-screen layer in conjunction with the LED lights on the backlight board layer. Not only the display area can achieve the display effect, but also the area outside the display area, that is, the touch area, can achieve the display effect. This solution allows production workers to design the display area to be smaller by placing a large number of UI controls in the display area to the touch area outside the display area for display, which helps to reduce the production cost of the display area. In the case of a touch color screen of equal area, reducing the area of ​​the display area will relatively increase the area of ​​the touch area. When the increased cost of the touch area is not higher than the reduced cost of the display area, the production cost of the entire touch color screen will be reduced.

[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "splicing" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] A low-cost touch color screen comprises a display area 1 and a touch area 2, wherein the touch area 2 is located outside the display area 1;

[0022] The touch area 2 includes a semi-transparent glass layer 21, a silk screen layer 22, a touch layer 23 and a backlight board layer 24. The semi-transparent glass layer 21, the silk screen layer 22, the touch layer 23 and the backlight board layer 24 are arranged in sequence from top to bottom. The silk screen layer 22 is provided with icons of several UI controls (not marked in the figure), and the backlight board layer 24 is provided with several LED lights (not marked in the figure). The icons of the several UI controls correspond one to one with the several LED lights.

[0023] A low-cost touch color screen of the present application is applied to a thermostat, such as Figure 1-2 As shown, the display area 1 can display the temperature changes indoors and outdoors, and the touch area 2 can be touched and controlled by the user. Since the silk screen layer 22 is provided with icons of several UI controls, the UI controls include a switch key, a return key, a confirmation key, a slide bar, and a slide knob. Since the backlight panel layer 24 is provided with several LED lights, these LED lights can display different colors and brightness. Since the icons of several UI controls correspond one to one with several LED lights, the display effect of the UI control is achieved by controlling the LED lights. In one embodiment, when the user touches the icon of the switch key, the touch layer 23 receives the sampling signal of the switch key touch gesture, and feeds back the sampling signal of the switch key touch gesture to the central controller of the thermostat. The central controller can control the on and off of the LED light corresponding to the switch key icon to achieve the display effect of the switch key. When the LED light is on, the semi-transparent glass layer 21 will display the switch key icon. When the LED light is off, the semi-transparent glass layer 21 will not display the switch key icon.

[0024] This solution realizes the control icon display effect in the area outside the display area 1 by controlling the icons of the UI controls on the silk-screen layer in conjunction with the LED lights on the backlight board layer 24. Not only the display area 1 can achieve the display effect, but also the area outside the display area 1, that is, the touch area 2 can achieve the display effect. This solution allows production workers to design the display area 1 to be smaller by placing a large number of UI controls in the display area 1 in the touch area 2 outside the display area 1 for display, which helps to reduce the production cost of the display area. In the case of a touch color screen of equal area, reducing the area of ​​the display area will relatively increase the area of ​​the touch area. When the increased cost of the touch area is not higher than the reduced cost of the display area, the production cost of the entire touch color screen will be reduced.

[0025] Preferably, the touch area 2 further includes a touch driving circuit (not shown in the figure), and the touch driving circuit is electrically connected to the touch layer 23. In this embodiment, the touch layer 23 is activated by controlling the touch driving circuit, so that the touch layer 23 can collect the user's touch gesture signal.

[0026] Preferably, the touch area 2 further includes a backlight driving circuit (not shown in the figure), which is electrically connected to the backlight board layer 24. In this embodiment, the on / off status of the LED lights on the backlight board layer 24 is controlled by controlling the backlight driving circuit.

[0027] Preferably, the icons of several UI controls are non-uniformly distributed on the silk-screen layer 22. In this embodiment, the icons of several UI controls are distributed following certain layout principles, and the layout principles followed by the icons of the UI controls are as follows: the size, shape and color of the icons should be consistent to improve recognition and user cognitive efficiency; the distribution of icons should be consistent with the user's operating logic and habits, such as putting icons of related functions together to form functional areas; appropriate spacing should be maintained between icons to avoid being too crowded or scattered, so as to improve the neatness and aesthetics of the interface.

[0028] Preferably, the LED lights on the backlight board layer 24 are RGB three-color LED lights. In this embodiment, since the LED lights on the backlight board layer 24 are RGB three-color LED lights, the current intensity of the RGB three-color light source of each LED light is independently controlled to achieve the effect of displaying different colors and brightness.

[0029] On the other hand, the present application provides a thermostat using a low-cost touch color screen, including the low-cost touch color screen provided in the embodiment of the present application. A thermostat using a low-cost touch color screen in the present solution, during the design process of the low-cost touch color screen, by placing a large number of UI controls in the display area 1 in the touch area 2 outside the display area 1 for display, thereby allowing production workers to design the display area 1 to be smaller, which is conducive to reducing the production cost of the display area. In the case of touch color screens of equal area, reducing the area of ​​the display area will relatively increase the area of ​​the touch area. When the increased cost of the touch area is not higher than the reduced cost of the display area, the production cost of the entire touch color screen will be reduced, thereby reducing the production cost of the thermostat.

[0030] The technical principle of the present invention is described above in conjunction with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanations herein, those skilled in the art can associate other specific implementations of the present invention without paying creative labor, and these methods will fall within the scope of protection of the present invention.
