Abstract

The invention discloses a data storage circuit, which includes at least one resistive variable unit; after undergoing a set process of different currents, the resistive variable unit can form different resistance values ​​to be stored as data. The invention also discloses an array substrate, a display device, a data writing method, and a data reading method. The data storage circuit and its data reading and writing method, array substrate, and display device provided by the present invention can solve the existing problems of difficulty in setting or reading production information.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a data storage circuit and a data reading and writing method thereof, an array substrate, and a display device. Background technique [0002] At present, during the production process of liquid crystal display panel factories, the panel ID information is usually recorded by laser marking the metal film layer (two-dimensional code); but after the display panel is thinned, due to appearance reasons such as pits / dirty, As a result, the panel ID information cannot be read normally in the display module factory. [0003] However, the aforementioned two-dimensional code must be exposed because of the reading method, and cannot be hidden in the display panel, so that an additional space for setting the two-dimensional code needs to be reserved on the display panel. Today’s display products are more and more pursuing narrow bezels when designing. Some products have too narrow b...
