Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

First, terms referred to in the embodiments of the present application are described:

the cash register comprises: the computer equipment is used in places for processing counter business, such as commodity retail enterprises, restaurant and restaurant, bank counters and the like. The cash register can store unit price, stock information and a sales list of the goods, and can realize functions of collecting cash, printing sales receipts, issuing invoices, acquiring information of the goods by scanning bar codes of the goods (such as unit price, purchase quantity, stock information and the like of the goods) by being connected with peripherals such as a point of sale information management system (namely, a point of sale (pos) machine), a bill printer, a scanning reader and the like.

The payment device: refers to a computer device having payment functionality. Exemplary payment devices include self-service payment devices and add-on payment devices. The self-service payment device has the same function as a cash register, can store unit price, inventory information and sales lists of commodities, and has the functions of collecting money, printing sales receipts, issuing invoices, acquiring information of the commodities by scanning barcodes of the commodities and the like. The external payment equipment is connected with the cash register and has the functions of receiving order information and collecting money of the cash register, and the order information comprises commodity information of commodities purchased by customers. For example, the payment device may implement two-dimensional code payment and face recognition payment functions through a barcode scanner or a camera module disposed on the payment device. Illustratively, the camera module is a 3D camera module.

A touch display screen: the present invention relates to a display device capable of receiving an input signal in a touch form. The touch display screen is used for positioning an input signal through the absolute coordinate positioning system, and when the touch display screen is connected with the first machine body, the touch display screen is touched to control the first machine body.

3D (three dimensions) camera module: refers to an assembly containing a three-dimensional (3D) camera, consisting of a plurality of cameras and a depth sensor. The method can acquire a conventional planar image, can acquire depth information of a shot object, namely three-dimensional position and size information, and can be applied to multiple fields of man-machine interaction, face recognition, gesture recognition, three-dimensional modeling, Augmented Reality (AR), security and assistance, driving and the like.

A code scanner: a machine for reading graphic code information, such as a scanned bar code or two-dimensional code. The code scanner is internally provided with an inductor which emits an infrared light source to the graphic code, and the chip in the code scanner is utilized to decode the graphic code according to the reflection result of the graphic code and output the result represented by the graphic code.

For example, in a place where counter business is handled, such as a retail establishment for goods, a restaurant and restaurant, a supermarket, or a bank counter, settlement using a payment apparatus is required. For example, when the payment device is a payment device capable of self-service settlement, a customer may scan a graphic code of a commodity by using a code scanner on the payment device, or select a commodity to be purchased through a program installed on the payment device, and display commodity information of the commodity on a display screen of the payment device, for example, a commodity name, a purchase amount, a commodity unit price, a commodity total price, inventory information, sales information, and the like, the user may generate a commodity order to enter a payment step by operating the display screen, and a two-dimensional code payment or a face recognition payment is completed through the code scanner or the 3D camera module of the payment device. For example, when payment equipment is the external payment equipment who links to each other with the cash registering machine, the trade company can input commodity information on the cash registering machine, with commodity information transmission to payment equipment, carries out the payment step on payment equipment, and the user accomplishes two-dimensional code payment or face identification payment through payment equipment's bar code collector or 3D camera module. Or, the merchant can input commodity information on a display screen of the payment device to generate a commodity order, and the customer completes two-dimensional code payment or face recognition payment through a code scanner or a camera module of the payment device.

In the related art, two display screens of the multimedia device are arranged in opposite directions, and the two display screens respectively face two opposite directions to display contents to different users. In some application scenarios, the two display screens are opposite to each other, so that different users cannot observe the display screens at a right viewing angle. For example, in one application scenario, where the multimedia device is a payment device, the viewing angle of the customer viewing the payment device is 135 ° from the viewing angle of the merchant viewing the payment device, then two 180 ° display screens disposed opposite each other would not allow both the customer and the merchant to view the display screens at the opposite viewing angles.

For example, the multimedia device of the present application is not limited to a payment device, and may be an advertisement display device having two display screens, a vending machine device, a computer, a television, an LED (Light Emitting Diode) display device, and the like.
