Description

Technical Field

[0001] This utility model belongs to the field of POS terminal technology, and in particular relates to a POS terminal with multiple types of displays. Background Technology

[0002] In the current POS terminal market, display screen types are relatively limited, with most only equipped with TFT displays or segment displays. While TFT displays can present rich and vibrant images and text information, they suffer from high power consumption and relatively high cost in some simple data display and low-power consumption scenarios. Segment displays, especially TA segment displays, while offering advantages such as low power consumption, low cost, and clear display of simple numbers and characters, have limited content richness. For some commercial applications that require both complex information display and efficient display of simple data, and have strict requirements on power consumption and cost, such as small convenience stores and street food stalls, POS terminals with a single display screen cannot meet diverse needs. Summary of the Invention

[0003] The purpose of this utility model is to provide a POS terminal with multiple types of displays in order to solve the above-mentioned problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a POS terminal with multiple types of displays, comprising a central processing unit, and a first display, a second display, a segment code linkage control module, a storage module, a communication module, and a power supply module electrically connected to the central processing unit; The central processing unit (CPU) is responsible for processing the transaction logic of the POS terminal, coordinating the work of various modules, and executing system instructions. The first display screen is used to display the interactive interface; The second display screen is used to show concise information; The segment code linkage control module receives display data and instruction signals from the central processing unit, and intelligently determines and allocates different data to the first display screen and the second display screen according to the display content and priority, so as to coordinate the linkage and synchronous display of the first display screen and the second display screen. The storage module stores transaction data, product information, and system programs, and supports data reading, writing, and persistent storage. The communication module enables the POS to connect with external devices or networks, transmit transaction data, and download and update data. The power module provides stable power to the various components of the POS terminal; The first display screen is a TFT display screen; The second display screen is a TA segment code screen.

[0005] As a further description of the above technical solution: The segment code linkage control module interacts with the storage module to obtain various data resources required for display; when the communication module transmits transaction data to an external server, the segment code linkage control module will also adjust the data transmission status accordingly.

[0006] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. In this utility model, the linkage control module of TFT+TA segment code solves the problems of the existing POS terminal display screen having a single function, being unable to meet multiple display needs and cost and power consumption, and realizes the collaborative work of different types of display screens, thereby improving the applicability and performance of the POS terminal.

[0007] 2. In this utility model, the combined use of the TFT display screen and the TA segment code screen fully leverages the advantages of both, which can meet the needs of complex information display while efficiently displaying simple data, thereby improving the user experience and the ease of operation for merchants.

[0008] 3. In this utility model, by making reasonable use of the TA segment code screen to display simple information, the dependence on the TFT display screen is reduced, the hardware cost is lowered, and the POS terminal becomes more price-competitive.

[0009] 4. The intelligent power consumption management function effectively reduces the overall power consumption of the POS terminal, which is in line with the development trend of energy conservation and environmental protection. It is especially suitable for mobile POS application scenarios with limited power. It is applicable to a variety of business scenarios. Whether it is a large shopping mall or a small retail store, it can flexibly utilize the characteristics of the two displays according to its own needs to improve service efficiency and quality.

[0012] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0013] Please see Figure 1 This utility model provides a technical solution: a POS terminal with multiple types of displays, including a central processing unit 1, and a first display 2, a second display 3, a segment code linkage control module 4, a storage module 5, a communication module 6 and a power supply module 7 electrically connected to the central processing unit 1; Central Processing Unit 1 (CPU 1) is responsible for processing the transaction logic of the POS terminal, coordinating the work of various modules, and executing system instructions. The first display screen 2 is used to display the interactive interface; The second display screen 3 is used to display concise information; The first display screen 2 is a TFT display screen; The second display screen 3 is a TA segment code screen; The segment code linkage control module 4 receives display data and instruction signals from the central processing unit 1, and intelligently determines and allocates different data to the first display screen 2 and the second display screen 3 according to the display content and priority, and coordinates the linkage and synchronous display of the first display screen 2 and the second display screen 3. For complex information such as detailed product descriptions and promotional displays, the control module transmits the data to the TFT display screen for display; while for simple information such as transaction amount, quantity, and payment status, it prioritizes sending it to the TA segment display screen. When a transaction is made, the TFT display shows the product details and transaction process animation, while the TA segment code display shows the change of the transaction amount in real time. The two work together to provide users and merchants with a comprehensive and clear information display. When there is no need to display complex information for a long time, the brightness of the TFT display screen is automatically reduced or even put into sleep mode, and only the TA segment code screen is kept displaying key data, thereby effectively reducing the power consumption of the entire POS terminal. Storage module 5 stores transaction data, product information, system programs, etc., and supports data reading, writing and persistent storage; Communication module 6 enables the POS to connect with external devices or networks, transmit transaction data, and download and update data; Power module 7 provides stable power to the various components of the POS terminal; The segment code linkage control module 4 interacts with the storage module 5 to obtain various data resources required for display; when the communication module 6 transmits transaction data to an external server, the segment code linkage control module 4 will also adjust the data transmission status accordingly.

[0014] Working Principle: First, the central processing unit 1, TFT display screen, TA segment code screen, segment code linkage control module 4, storage module 5, communication module 6, and power supply module 7 are assembled in a compact and reasonable layout to ensure stable electrical connections and smooth signal transmission between modules. Second, after the equipment is assembled, the parameters of the segment code linkage control module 4 are set, including display content allocation rules, priority settings, and synchronization parameter configuration. The entire POS terminal is fully debugged using professional debugging tools to ensure accurate linkage effect of the display screen and normal operation of power management function. Finally, during commercial transactions, when a customer checks out, the central processing unit 1 sends transaction-related data to the segment code linkage control module 4. The segment code linkage control module 4 sends detailed product information to the TFT display screen according to preset rules, and simultaneously sends simple data such as transaction amount and quantity to the TA segment code screen. After the transaction is completed, based on the feedback from the communication module 6, a payment success or failure prompt message is displayed on the display screen. In normal standby mode, the segment code linkage control module 4 automatically adjusts the working state of the display screen according to the power management strategy to reduce energy consumption.

[0015] 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.
