Abstract
(EN)
The invention relates to an electronic device (10) including a liquid crystal display screen (14) and a control card (16), the electric tracks (22, 26) of the card (16) and the screen (14) being connected by means of a connector (28), the control card (16) comprising a microcontroller (24) capable of applying electric voltage to at least one connection pad (30), with a view to displaying a given piece of information on the screen (14), characterized in that the control card (16) comprises a diagnostic device (36) which is provided for generating a voltage pulse (V1) on connection pads (30) and for measuring the resulting electric voltage (V2), with a view to determining the status of the connection between the screen (14) and the card (16), on the basis of the value of the measured electric voltage (V2).
