Abstract: The present invention discloses an array substrate and a method for preparing the same, and a display device. The array substrate comprises a substrate, and a thin-film transistor and a passivation layer formed on a side of the substrate, and the array substrate is divided into a reflective region and a transmissive region, wherein an insulating layer is formed on the reflective region on a side of the passivation layer that is far from the substrate, and a nanoparticle layer for diffuse reflecting an incident light is formed on a side of the insulating layer that is far from the substrate. Not only the viewing angle of the array substrate is enlarged, but also the performances of the array substrate such as transmittance, contrast and dark-state uniformity are guaranteed, thus the present invention is especially applicable for display devices for large-scale outdoor display.

Abstract: An array substrate and a display device are disclosed. A coating layer (8) is disposed between a base substrate (1) and a first transparent conductive oxide film layer (2), a refractive index of the coating layer (8) is bigger than that of the base substrate (1) and smaller than that of the first transparent conductive oxide film layer (2). A multi-layer reflection phenomenon caused by the relatively big difference between the refractive indexes of the base substrate 1 and the first transparent conductive oxide film layer 2 can be weakened, thereby the light transmission rate of the array substrate may be improved.

Abstract: Disclosed is a liquid crystal module detection apparatus for detecting image-sticking, and a detection and evaluation system and method. The apparatus comprises: a sealed thermal-insulating transparent container (1), adapted to contain a liquid crystal module (5) to be tested; a temperature-control module, adapted to adjust the temperature inside the container; a signal generator module (4), adapted to provide a drive signal to the liquid crystal module to be tested. The apparatus employs a sealed, well thermal-insulating, transparent container, and utilizes the heat emitted from the panel and the backlight of the module itself to form a desired temperature environment for detection.
