Abstract: A display screen assembly is suitable for use in a digital device that lacks the processing power, memory, or both needed to carry out light-simulated bar code processing. The display screen assembly includes a display screen having a display area and mounted to a flexible circuit. The flexible circuit includes numerous conductive circuit traces including terminal ends, and various electronic components such as a controller and a screen driver. The various components may be covered by a cover layer, and the display screen including the display area may be covered by a sheet of transparent material. An LED may be generally positioned near an edge or corner of the display screen, and may be may be controlled by a digital device processor or by the controller on the flexible circuit, as desired, for producing light-simulated bar codes.
