Disclosed are an array substrate and a manufacturing method therefor, a display panel and a display device, which are used for enabling a viewer to see a uniform reflective effect at various viewing angles, improving the display effect. The array substrate manufacturing method comprises: sequentially forming, on a passivation layer, a reflective layer and a transparent conductive layer, the reflective layer being electrically connected, by means of a via hole penetrating through the passivation layer, to a source electrode or a drain electrode of the thin film transistor, and the transparent conductive layer comprising several metal ions; performing reduction process on the transparent conductive layer, so that the metal ions are reduced, and a metal particle layer is formed; and performing patterning process on the transparent conductive layer and the reflective layer on which the steps above are completed, so as to form a pixel electrode.

Array substrate and manufacturing method therefor, display panel, display device

An optical touch screen and a display device are disclosed. The optical touch screen () comprises an optical touch panel () and a first sensor () and a second sensor (). The optical touch panel () comprises a first optical transmission channel () and a second optical transmission channel () which are intersected with each other. The first sensor () is disposed on at least one end of the first optical transmission channel () and configured to receive light emitted by the first optical transmission channel (). The second sensor () is disposed on at least one end of the second optical transmission channel () and configured to receive light emitted by the second optical transmission channel (). The optical touch screen and the display device can improve the positioning accuracy of the touch position.
