Abstract: A display device driving method includes: converting a plurality of first luminance signals corresponding to a plurality of pixels to a plurality of second luminance signals; and driving a display component based on the plurality of second luminance signals. The converting includes: calculating a weight corresponding to a lighting period of the display component, based on the plurality of first luminance signals or the plurality of second luminance signals; calculating a cumulative value that is an accumulation of a value corresponding to the weight; calculating, based on the cumulative value, a reduction rate at which each of the plurality of first luminance signals is to be reduced; and calculating the plurality of second luminance signals, based on the reduction rate and the plurality of first luminance signals.

Abstract: [Problem]
Provides a tiling display has a structure that prevents deterioration in display quality due to light reflection at the seams of self-luminous panels in the tiling panel.
[Solution]
A tiling panel formed by arranging a plurality of self-luminous panels, Each of the several self-luminous panels has a main display area as a display area and a main display area on the front side. It has a sub-display area that is connected to the display area and has a part that bends toward the back of the panel. The two self-luminous panels that meet each other are arranged so that the sub-display areas of each other are close to each other, and theIn the sub-display area, a circularly polarizing layer is formed on the light input/output path.

Abstract: A self-luminous display panel in which pixels composed of sub-pixels are arranged, including light-emitting elements and a light-shielding film. The light-emitting elements correspond one-to-one with the sub-pixels, each sub-pixel in a pixel emitting a different color of light. The light-shielding film is provided with openings at positions corresponding to the light-emitting elements in plan view, downstream in a light emission direction of the light-emitting elements. Optical distances between the light-shielding film and light emission reference points of the light-emitting elements are different, depending on light emission color of the light-emitting elements.

Abstract: A patterning device performs patterning in manufacture of a display panel in which thin films including an organic film are laminated above a substrate. The patterning device includes a chamber, light transmissive plates, and a laser emitter. The chamber has a light transmissive window including a first light transmissive plate through which a laser beam is transmitted and accommodates a thin film laminated substrate. A second light transmissive plate through which the laser beam is transmitted is in the chamber between the first light transmissive plate and the thin film laminated substrate at a position spaced away from the thin film laminated substrate. The laser emitter is outside the chamber and emits the laser beam towards the thin film laminated substrate, through the first light transmissive plate and the second light transmissive plate, to irradiate and remove a portion of the thin film.
