DISPLAY DEVICE, RECEIVER, AND TEST APPARATUS

摘要

A display device (3) comprises an inspection circuit (35) for inspecting a data reception related circuit (34) to generate inspection information, an inspection result image generation circuit (37) for generating image data indicating the inspection information, a display switching circuit (36) for superimposing inspection result image data on test video data, and a display unit (31) for displaying the test video data superimposing the inspection result image data. As a result, it is possible to carry out inspection after assembly of the display device (3) without disassembling the display device (3). This in turn makes it possible to carry out a test in a simple manner on the data reception related circuit (34) inside the display device (3) without changing noise environment inside the display device (3).
