[0020] Figure 1 is an overall system configuration diagram for performing the method of selling defective panel refurbished products according to the present invention.

[0021] The central server (100) collects information on defective panels and notifies the buyer terminal (200) of the collection location and collection box of the defective panels.

[0022] In addition, the central server communicates with a tester who analyzes defects in defective panels, and the central server (100) can classify panels that are repairable and panels that are not.

[0023] In addition, the central server (100) can notify the refurbished producer terminal (300) of the part to be repaired or replaced due to a defect, and can register the refurbished product on the online market server (500).

[0024] Furthermore, the central server (100) collects feedback including reviews from consumer terminals (600), collects usage data, and grants reward points and an additional warranty period to consumer terminals that provide feedback.

[0025] In addition, the central server (100) transmits frequently occurring problems to the manufacturer server (400).

[0026] Here, the buyer terminal (200) or consumer terminal (600) refers to any type of terminal capable of receiving information or messages sent from the central server (100) according to the present invention in the form of data, and may be implemented as a computer, portable terminal, television, or wearable device; the computer includes, for example, a notebook, desktop, or laptop equipped with a web browser, and the portable terminal is, for example, a wireless communication device that guarantees portability and mobility, such as a PCS (Personal Communication System), PDC (Personal Digital Cellular), PHS (Personal Handyphone System), PDA (Personal Digital Assistant), GSM (Global System for Mobile communications), IMT (International Mobile Telecommunication)-2000, CDMA (Code Division Multiple Access)-2000, W-CDMA (W-Code Division Multiple Access), Wibro (Wireless Broadband Internet), smartphone, or mobile WiMAX (Mobile Worldwide Interoperability for It may include handheld-based wireless communication devices capable of using all types of wireless communication, such as Microwave Access, Bluetooth, and Wi-Fi. Additionally, television may include IPTV (Internet Protocol Television), Internet TV, terrestrial TV, cable TV, etc.Furthermore, the wearable device is a type of information processing device that can be worn directly on the human body, such as a watch, glasses, accessories, clothing, or shoes, and can transmit and receive various messages in the form of data to and from a central server (100) via a wired or wireless network, either directly or through another information processing device.

[0027] Meanwhile, the above-mentioned tester may be a structured light. Structured lighting is a method of projecting a specific light pattern (e.g., grid, linear pattern, etc.) onto a surface to highlight and detect surface defects, scratches, or curvature. Through this, the location, size, and shape of defects are visualized by analyzing the distortion or reflection of the lighting.

[0028] Furthermore, it is advisable to automatically analyze the degree of pattern distortion by utilizing deep learning-based algorithms.

[0029] FIG. 2 is a perspective view of a tester that performs the method of selling defective panel refurbished products according to the present invention.

[0030] As shown in FIG. 2, the tester (900) is largely composed of a defective panel (910), a reflective support (920), and a light (930).

[0031] When a light (930) projects a dense grid pattern in the X and Y directions onto a defective panel (910), the area distorted by the defect can be easily tracked.

[0032] Alternatively, parallel lines can be projected to make defects appear as distortions or breaks in the lines.

[0033] Furthermore, it is possible to highlight detailed defects by projecting irregular or regular dots through a dot pattern, or to detect complex curved surface defects by projecting curved patterns through a wave pattern.

[0034] The reflective support (920) supports the lower surface of the defective panel (910) and is preferably equipped with a screen capable of sensitively receiving light irradiated from the lighting. The image projected onto the screen is preferably displayed on a computer screen.

[0035] With the tester (900) as described above, the present invention can easily integrate the repair, resale, and response management processes of refurbished products through the prompt and accurate detection of defects.

[0036] Figure 3 is an overall flowchart of a method for selling defective panel refurbished products that can be performed by the defective panel refurbished product sales system of the present invention.

[0037] First, the central server (100) proceeds with the step (S10) of collecting information about defective panels.

[0038] At this stage, it is recommended that the buyer register the information of the defective panel on the buyer's terminal platform.

[0039] Here, "information on a defective panel" refers to the defective product itself or the information of the display device equipped with the defective panel, including product information such as the model name or serial number and the problem thereof.

[0040] Next, the central server (100) proceeds with the step (S20) of notifying the buyer terminal (200) of the collection location and collection box of the defective panel.

[0041] It is preferable for the refurbished manufacturer to collect the defective panel through a logistics service when the buyer, who has been notified of the aforementioned collection location and collection box, returns the panel through the designated location and box.

[0042] Preferably, it is best to manage the collection route using RFID and GPS tracking systems.

[0043] Next, a tester capable of communicating with the central server (100) analyzes the defects of the defective panel, and the central server (100) proceeds with the step (S30) of classifying the panel into repairable and unrepairable panels.

[0044] The tester here can be a high-resolution optical scanner and can also use artificial intelligence to automatically analyze the types of defects in defective panels. Here, defects refer to dead pixels, white pixels, circuit damage, etc.

[0045] Once a defect is detected, the central server (100) classifies the repairable panels and the unrepairable panels along with product information.

[0046] Next, the central server (100) proceeds with the step (S40) of notifying the refurbished producer terminal (300) of the part to be repaired or replaced due to a defect.

[0047] Next, the central server (100) proceeds with the step (S50) of registering the refurbished product to the online market server (500).

[0048] Here, it is recommended that the central server register the condition of refurbished products according to their grade, along with the warranty period, through the market server's platform. Furthermore, it is also recommended to set prices according to the grade.

[0049] Next, the central server (100) proceeds with a collection step (S60) in which it collects feedback, including reviews, from a consumer terminal (600) that has consumed a refurbished product and collects usage data.

[0050] It is recommended to include star ratings in the above reviews and complaints and suggestions for improvement in the usage data.

[0051] Next, the central server (100) proceeds to the step (S70) of granting compensation points and an additional warranty period to the consumer terminal that provided feedback.

[0052] Since consumers may submit dishonest reviews if there is no compensation, reward points are granted, and furthermore, an extended warranty period may be provided.

[0053] Next, the central server (100) proceeds with the step (S80) of transmitting frequently occurring problems to the manufacturer server (400).

[0054] The manufacturer refers to the party that originally produced the product containing the defective panel. It is advisable to report frequently occurring problems not only to the manufacturer but also to the repair center. This allows for improvements in the design or process to resolve recurring defects.

[0055] As described above, according to the present invention, electronic waste can be reduced through the recycling of defective panels, resources and energy required for the production of new panels can be saved, and trust can be increased by continuously improving quality based on consumer feedback.

[0056] Furthermore, integrating the processes of collection, repair, resale, and response management offers the advantageous effect of reducing time and costs.

[0057] The method for selling defective panel refurbished products according to the present invention described above may be implemented or performed through various exemplary logics, logic blocks, modules, and circuits using a general-purpose processor, a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field programmable gate array (FPGA), or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or a combination of those designed to perform these functions.

[0058] A general-purpose processor may be a microprocessor, but in an alternative embodiment, such a processor may be a conventional processor, controller, or microcontroller. The processor may also be implemented as a combination of computing devices, such as, for example, a DSP and a microprocessor, a plurality of microprocessors, one or more microprocessors combined with a DSP core, or a combination of these configurations.

[0059] Herein, the steps of the method or algorithm described above in relation to the disclosed embodiments may be directly implemented by hardware, a software module executed by a processor, or a combination thereof. The software module exists within RAM memory, flash memory, ROM memory, EPROM memory, EEPROM memory, registers, a hard disk, a portable disk, a CD-ROM, or any form of storage medium known in the art. An exemplary storage medium is combined with a processor, so that the processor reads information from the storage medium and writes information to the storage medium. Alternatively, the storage medium may be integrated into the processor. Such a processor and storage medium are located in an ASIC. The ASIC may be located in a user terminal. Alternatively, the processor and storage medium may exist as discrete components in the user terminal.

[0060] The description of the presented embodiments is provided so that any person skilled in the art can use or practice the present invention.

[0061] Various variations of these embodiments will be obvious to those skilled in the art.
