Abstract

The invention discloses a test method and a test device for an MHL port. The method comprises the following steps: establishing connection with the MHL port of a television to be tested; and acquiringthe voltage of each pin of the MHL port of the television to be tested, and testing the MHL port according to the voltage of each pin and the EDID acquisition operation executed on the television tobe tested. The technical problems that an existing method for testing the television MHL function is high in testing cost and low in testing efficiency are solved.

Description

technical field [0001] The invention relates to the field of television, in particular to a test method and a test device for an MHL port. Background technique [0002] Before being assembled into a complete TV set, it is necessary to test the function of the TV MHL port (Mobile High-Definition Link, a standard port for high-definition audio and video on mobile terminals). Since it is not assembled into a complete machine and does not have a display screen, it is necessary to connect the TV motherboard, external image collector and mobile phone together. The TV motherboard obtains the mobile phone screen through the TV MHL port and outputs it to the external image collector in the form of a signal. However, this test method requires a specific mobile phone and a collector, and the investment cost is relatively large, and the test efficiency is low. [0003] The above content is only used to assist in understanding the technical solution of the present invention, and does no...
