Abstract
The display screen (11) is made of pixels (P) connected to one edge (11a) of the screen by wires (12) separated by a given pitch (s) so as to be controlled by respective terminals (18) of integrated circuits (16) outside the screen. The terminals (18) of each integrated circuit are disposed in a plurality of parallel rows (19) in which they are separated from one another by a pitch (Sm) equal to several times the pitch of the wires. Each integrated circuit is mounted on a connecting support (10) formed by an insulating film (21) carrying conductive tracks (23) connecting the terminals of the integrated circuit to the corresponding wires of the screen, the tracks extending substantially at the pitch of the wires. The mounting is done simply by collective reflow of bumps between the tracks (23) and the terminals (18), and the support (10) makes it possible to test the integrated circuits before they are mounted on the screen.
