Ultra-thin high-brightness rigid touch screen

Abstract

This utility model discloses an ultra-thin, high-brightness rigid touchscreen, relating to the field of touchscreen technology. It includes a touchscreen body comprising a display layer, a functional layer, and a protective layer. The display layer has multiple function indicator patterns. A high-brightness display component is located between the display layer and the functional layer. The high-brightness display component contains a copper pad fixedly mounted on the lower surface of the display layer and an OLED lamp fixedly mounted on the upper surface of the functional layer, with each copper pad corresponding to a different OLED lamp. When the touchscreen body is connected to a power source, the OLED lamps emit light. The light emitted by the OLED lamps strikes the copper pads. Due to the extremely smooth surface of the copper pads, all the light rays are reflected neatly in the same direction according to the law of "angle of incidence equals angle of reflection," forming a very bright spot on the copper foil. This significantly increases the brightness of the lights corresponding to the buttons on the touchscreen body, allowing operators to clearly distinguish the indicator lights even during daytime use.

Description

Technical Field

[0001] This utility model relates to the field of touch screen technology, and in particular to an ultra-thin, high-brightness rigid touch screen. Background Technology

[0002] A touchscreen essentially integrates a sophisticated mechanical pressing mechanism beneath the screen. It's not typically the entire screen that can be pressed; rather, specific areas of the screen can be pressed, functioning as one or more large buttons. These buttons are accompanied by backlighting to indicate their functions to the operator.

[0003] In existing technologies, the brightness of touch screens is generally low. When using a touch screen during the day, operators often find it difficult to distinguish the indicator lights, resulting in a poor user experience and failing to meet people's needs. Utility Model Content

[0004] The purpose of this invention is to provide an ultra-thin, high-brightness rigid touchscreen to address the issue of generally low brightness in touchscreens.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An ultra-thin, high-brightness rigid touchscreen includes a touchscreen body, which comprises a display layer, a functional layer, and a protective layer. The display layer has multiple function indicator patterns. A high-brightness display component is provided between the display layer and the functional layer. The high-brightness display component has copper pads fixedly installed on the lower end face of the display layer and OLED lights fixedly installed on the upper end face of the functional layer, with the copper pads corresponding one-to-one with the OLED lights.

[0006] As a further description of the above technical solution: the high-brightness display component includes a copper foil fixedly mounted on the upper surface of the functional layer, and the OLED lamp is located inside the copper foil.

[0007] As a further description of the above technical solution: the display layer is a colored PVC panel, the functional layer is a double-sided PCB panel, and the protective layer is divided into a PVC protective layer and a PET protective layer.

[0008] As a further description of the above technical solution: light-blocking cotton is filled between the display layer and the functional layer. The light-blocking cotton is fluffy and completely covers the external space of the copper foil and copper pad.

[0009] As a further description of the above technical solution: a digital display is provided in the middle of the touch screen body.

[0010] As a further description of the above technical solution: a connecting line is provided on the side of the touch screen body, and a signal processing unit is provided inside the connecting line.

[0011] As a further description of the above technical solution: the signal processing unit includes a control chip and a driver chip fixedly installed in the connection line.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: After the touchscreen is connected to a power source, the OLED light emits light, which shines onto the copper pad. Because the surface of the copper pad is extremely smooth, all the light rays are reflected neatly in the same direction according to the law that "the angle of incidence equals the angle of reflection," resulting in a very bright spot on the copper foil. The brightness of the lights corresponding to the buttons on the touchscreen is greatly improved, and even when the touchscreen is used during the day, the operator can clearly distinguish the light indications.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example: This example provides an ultra-thin, high-brightness rigid touchscreen. See [link / reference]. Figure 1 - Figure 3Specifically, it includes a touch screen body 1, which includes a display layer 11, a functional layer 12 and a protective layer 13. The display layer 11 is provided with multiple function indicator patterns 4. A high-brightness display component is provided between the display layer 11 and the functional layer 12. The high-brightness display component is provided with a copper pad 22 fixedly installed on the lower end face of the display layer 11 and an OLED lamp 21 fixedly installed on the upper end face of the functional layer 12. The copper pad 22 and the OLED lamp 21 correspond one-to-one. The high-brightness display component includes a copper foil 2 fixedly installed on the upper end face of the functional layer 12. The OLED lamp 21 is located inside the copper foil 2. After the touch screen body 1 is connected to the power supply, the OLED lamp 21 emits light. The light emitted by the OLED lamp 21 shines on the copper pad 22. Since the surface of the copper pad 22 is extremely smooth, all the light will be reflected neatly in the same direction according to the law that "the angle of incidence equals the angle of reflection". This will form a very bright spot on the copper foil 2, greatly improving the brightness of the lights corresponding to the buttons on the touch screen body 1. Even if the touch screen is used during the day, the operator can clearly distinguish the light indication. It should be noted that there is a height difference between the copper pad 22 and the copper foil 2, which allows the light emitted by the OLED lamp 21 to have a certain propagation path, thereby expanding the display range of the light spot; The thickness of the entire touchscreen is no more than 5mm, making it thin, practical, and space-saving. The display layer 11 is a colored PVC panel, the functional layer 12 is a double-sided PCB panel, and the protective layer 13 is divided into a PVC protective layer and a PET protective layer. The PVC panel allows the display layer 11 to undergo elastic deformation, ensuring that the display layer 11 can return to its original state after being pressed. The double-sided PCB is a rigid circuit board to meet the rigidity requirements of the overall touch screen. The PVC layer has strong waterproof performance, and the PET layer has high strength, impact resistance, wear resistance, and good rigidity. It can also provide effective heat insulation protection under the normal operating temperature of the touch screen. Light-blocking cotton 3 is filled between the display layer 11 and the functional layer 12. The light-blocking cotton 3 is fluffy and completely covers the external space of the copper foil 2 and the copper pad 22. The light-blocking cotton 3 completely fills the cavity between the display layer 11 and the functional layer 12, leaving only the space for the copper pad 22 to move downwards. This space is also the propagation space for the light emitted by the OLED lamp 21, which also allows for high light spot concentration and high brightness. When the operator presses the function indicator pattern 4, the corresponding copper pad 22 will move downwards, and the nearby light-blocking cotton 3 will be compressed until it contacts the copper foil 2, completing the action instruction. After that, the copper pad 22 will return to its original position under the elastic force of the display layer 11. A digital display 5 is located in the middle of the touch screen body 1; The digital display 5 can display relevant data for the corresponding function, so that the operator can make accurate adjustments and allow the appliance to quickly reach the predetermined operating condition; A connecting line 6 is provided on the side of the touch screen body 1. A signal processing unit is provided inside the connecting line 6. The signal processing unit includes a control chip 7 and a driver chip 71 that are fixedly installed inside the connecting line 6. Connect the end of the connecting wire 6 to the rated power supply to power on the entire touch screen. When the copper pad 22 contacts the copper foil 2, the copper foil 2 receives the electrical signal and transmits the signal to the control chip 7. The control chip 7 is responsible for analyzing the signal, decomposing it and converting it into a format that the driver chip 71 can understand, and then distributing it to the driver chip 71 for execution, driving the electrical appliances to perform corresponding actions and completing the adjustment of the electrical parameters.

[0017] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
