Description

Electronic price display device

An embodiment relates to an electronic price display device.

Typically, in a retail store, paper labels are used to display product information such as sale price or discount information, unit price, and country of origin for products on shelves. In the price display method using the paper label, when the product information is changed or the product display position is changed, the paper label which is in use has to be discarded and a new paper label has to be created. Therefore, maintenance costs are incurred constantly. Waste paper is wasted, which has a negative impact on environmental protection.

Therefore, research and development of an electronic price indicator (or an electronic shelf label (ESL)) as a means for replacing a conventional paper label is actively carried out.

These electronic price indicators were powered by the battery itself.

However, it was difficult to match the product and price when re-displaying the products displayed in the store, and it was clear that the installation environment and conditions of the electronic price indicator were different from each other. In addition, the power supply through the +/- wire through the copper wire is performed in the individual battery, but the width of the pattern is large, so that the mounting and the placement are limited.
