Description

  The present invention relates to a display, and more particularly to a display having nightlight and bill testing functions.

  In recent years, conventional cathode ray tube displays (commonly called CRT displays) have been gradually replaced by liquid crystal displays, the main cause being that the amount of radiation emitted by liquid crystal displays is much smaller than CRT displays, The production cost of liquid crystal displays has been remarkably reduced over the past few years, which is also the reason why liquid crystal displays are gradually becoming the mainstream in the TV or personal computer screen market. In addition, liquid crystal displays are lighter and thinner than conventional televisions that use cathode ray tubes, so more and more liquid crystal displays can be found in public places such as stations, hospitals, convenience stores, or movie theaters. In addition, the liquid crystal display can be used not only for displaying information but also for advertising purposes, and it can be said that commercial applications are becoming increasingly widespread.

  At business locations such as many stores and supermarkets, you can see people using liquid crystal displays to display sales information and product materials. A business person buys and sells merchandise and receives banknotes, and then usually uses a banknote discriminator to identify true or fake bills. However, the liquid crystal display and the counterfeit identifier occupy a certain space, and a person who performs business needs to purchase these two types of devices at the same time, and only then can the business requirement be satisfied.

  However, purchasing and installing the two types of equipment is more space consuming, has higher commercial costs, and is not ideal enough. Furthermore, in many business locations, lighting is not good, and it is easy for people to mistakenly determine the authenticity of banknotes or to miscount banknotes.

  Thus, how to combine bill testing, lighting and display functions of liquid crystal displays to reduce commercial costs and save space is the goal of those skilled in the art.

  It is an object of the present invention to combine bill testing, illumination and display functions of a liquid crystal display to reduce commercial costs and save usage space.

In order to achieve the above object, the present invention provides a display having a nightlight and bill test function, and the display includes a microcontroller, a push key unit, and an ultraviolet light emitter. The push key unit includes an ultraviolet light key, and when the ultraviolet light key is pressed, the push key unit can output an ultraviolet light signal (S _UV ) to the microcontroller. The ultraviolet light emitter interconnects with the microcontroller, the microcontroller receives the ultraviolet light signal (S _UV ), drives the ultraviolet light emitter and emits ultraviolet light. Thereby, this display can achieve the function of a nightlight and a banknote test simultaneously via ultraviolet light.

Among the displays having the nightlight and bill test functions, the display includes a display unit and a magnetic detector, the push key unit includes a first detection key, and at least one magnetic field distribution data in the microcontroller. Is loaded and the first detection key is pressed, the push key unit outputs a first signal (S ₁ ) to the microcontroller, causes the microcontroller to drive the magnetic detection key, and the surrounding magnetic field. The distribution state is detected, it is determined whether the magnetic field distribution state is compatible with the magnetic field distribution data, and a display signal (S _DIS ) is output to the display unit. The display unit includes a first light source and a second light source. When the microcontroller is adapted, the display unit (S _DIS ) drives light emission of the first light source and determines that the display unit is not adapted. (S _DIS ) drives the emission of the second light source.

Among the displays having the nightlight and banknote test functions, the display includes a display unit, an infrared emitter, and an infrared receiver, and the push key unit includes a second detection key, and is included in the microcontroller. When one infrared image distribution data is loaded and the second detection key is pressed, the push key unit outputs a second signal (S ₂ ) to the microcontroller, and the infrared emitter is connected to the microcontroller. The infrared receiver can receive the infrared image distribution status of the object to be detected, and at the same time, the microcontroller can match the infrared image distribution data with the infrared image distribution data. And the display signal (S _DIS ) is output to the display unit. The display unit includes a first light source and a second light source. When the microcontroller is adapted, the display unit (S _DIS ) drives light emission of the first light source and determines that the display unit is not adapted. (S _DIS ) drives the emission of the second light source.

  Among the displays having the nightlight and bill test functions, the first light source or the second light source is a light emitting diode (LED).

  Among the displays having the above-mentioned night light and banknote test function, the first light source or the second light source has different light emission colors.

  Among the displays having the nightlight and bill test functions, the display unit is a screen display system (On Screen Display), and when the microcontroller determines that the microcontroller is compatible, the display unit displays the compliance information. When presenting and determining that the microcontroller is not compatible, the display unit presents non-conforming information. The conforming information includes text content or image content, or the nonconforming information includes text content or image content.

It is explanatory drawing when the display unit of the display of 2nd Example of this invention represents conformity. It is explanatory drawing when the display unit of the display of 2nd Example of this invention represents incompatibility.

Referring to FIGS. 1A-1C simultaneously, FIG. 1A shows a front view of the display of the first embodiment of the present invention, and FIG. 1B shows a side view of the display of the first embodiment of the present invention. FIG. 1C shows a functional block diagram of the display according to the first embodiment of the present invention. As shown in FIGS. 1A to 1C, the display 1 includes a microcontroller 17, a push key unit 16, an ultraviolet light emitter 11, a display unit 15, a magnetic detector 12, an infrared emitter 13, An infrared receiver 14. The push key unit 16, the ultraviolet emitter 11, the display unit 15, the magnetic detector 12, the infrared emitter 13, and the infrared receiver 14 are all individually connected to the microcontroller 17. The push key unit 16 includes an ultraviolet light key 163, a first detection key 161, and a second detection key 162. As shown in FIG. 1A, the ultraviolet light key 163, the first detection key 161, and the second detection key 162 are installed at the lower right front portion of the display 1 and are convenient for a person to press. The display unit 15 includes a first light source 151 and a second light source 152, and the first light source 151 and the second light source 152 are installed at the lower left part of the front of the display 1, and are measured by a person. Thus, it is convenient for determining the light / dark state of the first light source 151 or the second light source 152. In a preferred embodiment, the first light source 151 or the second light source 152 is a light emitting diode (LED), and the colors emitted by the first light source 151 and the second light source 152 are different from each other. Different. The ultraviolet light emitter 11 and the infrared light emitter 13 are installed at the lower edge portion of the front surface of the display 1. When the ultraviolet light key 163 is pressed, the push key unit 16 can output an ultraviolet light signal (S _UV ) to the microcontroller 17. After the microcontroller 17 receives the ultraviolet light signal (S _UV ), the ultraviolet light emitter 11 can be driven to emit ultraviolet light. Generally, the wavelength of ultraviolet light is about 365 nm.

  In order to solve the conventional defects, the present invention combines the bill test and illumination functions with the display 1 in particular. When the display 1 of the present invention is used, the emitted ultraviolet light can be used, and the detection object 9 is irradiated. Here, the detected object 9 is a bill waiting for authenticity identification. In general, the government of each country applies a specific pattern of light-emitting agent on the banknote because it is convenient for the authenticity identification function of the banknote. The fluorescent agent cannot be displayed under general visible light irradiation. However, the fluorescent agent exhibits a fluorescent reaction under exposure to ultraviolet light irradiation of the display 1 of the present invention. That is, under the excitation of ultraviolet light, the wavelength displayed is blue visible light of 420 to 460 nm. In this way, people discriminate the authenticity of banknotes depending on whether or not a fluorescent reaction has appeared. can do. Therefore, the display 1 of the present invention transmits ultraviolet light and achieves the bill test function.

Of course, with the current counterfeit technology, the method of identifying ultraviolet light is still insufficient. Therefore, the display 1 of the present invention further uses the magnetic detection technology to increase the accuracy of bill recognition. In general, in order to prevent misuse of counterfeit bills, the Samurai State uses magnetic ink on a banknote with a certain face value and prints it, and has a specific magnetic field distribution around the banknote. In order to achieve the purpose of magnetic detection, it is necessary to load at least one magnetic field distribution data into the microcontroller 17 of the display 1 of the present invention first, and the number of the magnetic field distribution data is the same as the number of the bill type. That is, when the bill face value to be detected has four types of 50 yuan, 100 yuan, 500 yuan, and 1000 yuan, the microcontroller 17 first needs to load different magnetic field distribution data of the four kinds of face values. There is. Thus, as shown in FIG. 1C, when the first detection key 161 is pressed, the press key 16 can output the first signal (S ₁ ) to the microcontroller 17. 17 is used to drive the magnetic detector 12 to detect the magnetic field distribution state (C _MAG ) around the bill, and at the same time, the magnetic field distribution state (C _MAG ) is any one of the four types of magnetic field distribution data. Then, using the determination result of the microcontroller 17, the microcontroller 17 can output a display signal (S _DIS ) to the display unit 15 in a relative manner. When the microcontroller 17 determines that it is compatible, the display signal (S _DIS ) drives the light emission of the first light source 151, and when it determines that it is not compatible, the display signal (S _DIS ) The light emission of the light source 152 is driven. Since the colors emitted by the first light source 151 and the second light source 152 are different, people can recognize the authenticity of the banknote by different light or color. That is, by using the magnetic detector 12, it is possible to detect the magnetic property of the magnetic ink of the bill of the detected object 9, and to analyze the magnetic property through the circuit to identify the authenticity of the bill. Therefore, the display 1 of the present invention can further have a night illumination, and achieves a highly accurate bill test function through magnetic detection.

In addition, the present invention can further improve the accuracy of banknote identification by using infrared imaging technology. Generally, a banknote prints a sheet of a special material with a variety of different inks using a multilayer repetitive printing method, so it is difficult for a counterfeit bill to completely imitate the sheet and the multilayer ink. Regarding physical properties, different materials, different component inks, and different coating layer thicknesses have different absorption and transmission effects for infrared rays. Accordingly, if the infrared absorption and transmittance of a single sheet is completely the same as a true bill, it can be determined that the sheet is a true bill. Using this principle, it is necessary to load at least one infrared imaging distribution data into the microcontroller 17 of the display 1 of the present invention first, and the number of the infrared imaging distribution data is the same as the number of banknote types. Yes, that is, when the bill face value to be detected has three types of 10 yuan, 200 yuan, and 500 yuan, the microcontroller 17 first needs to load different infrared imaging distribution data of the three kinds of face value bills. Thus, as shown in FIG. 1C, when the second detection key 162 is pressed, the press key 16 can output the second signal (S ₂ ) to the microcontroller 17, and the microcontroller 17 drives the infrared emitter 13 to emit infrared rays. When the infrared light passes through the detected object 9 (that is, a bill waiting for authenticity identification), the infrared receiver 14 may simultaneously receive the infrared imaging distribution status (C _IFR ) of the detected object 9. it can. At this time, the microcontroller 17 determines whether the infrared image distribution status (C _IFR ) _matches any one of the three types of infrared imaging distribution data; The microcontroller 17 can relatively output a display signal (S _DIS ) to the display unit 15 and drives the light emission of the first light source 151 or the second light source 152.

  In the said Example, this 1st light source 151 and the 2nd light source 152 utilize the difference in color, and display the authenticity of a banknote. In other embodiments, as shown in FIG. 1A, the first light source 151 and the second light source 152 may be the same color, for example, the first light source 151 and the second light source 152 here. It is necessary to add the sign contents 159 to the periphery of each, and this is used to make people understand the representative significance of the first light source 151 and the second light source 152. Or the 1st light source 151 and the 2nd light source 152 are via the external shape and outline of a different lamp head, and are convenient for a person's classification and interpretation. Thus, the bill authenticity recognition function can be achieved.

  In addition, the display unit is configured by hardware LEDs, and of course, the display unit of the present invention may be a software screen display system (On Screen Display). Referring to FIGS. 2A and 2B, FIG. 2A shows an explanatory diagram when the display unit of the display of the second embodiment of the present invention exhibits conformity, and FIG. 2B shows the present invention. It is explanatory drawing when the well display unit of the display of 2nd Example shows nonconformity. As shown in FIG. 2A, when the microcontroller of the display 2 determines that it is compatible, it means that the detected object 9 is a true bill. At this time, the display unit 25 presents a compliance signal 253. The matching signal 253 includes text content or image content. As shown in FIG. 2B, when it is determined that the microcontroller of the display 2 is not compatible, it means that the detected object 9 is a fake bill. The nonconforming signal 254 can also include text content or image content.

  As described above, the display having the nightlight and banknote test function disclosed in the present invention combines the functions of banknote test, lighting and display, so that the commercial cost can be reduced and the use space in the store can be saved. It is very convenient and practical.
