Display device, electronic apparatus and lighting device

A lighting device, comprising:

• a light guide plate;
• a plurality of light emitting elements aligned along a first side of the light guide plate in a direction from an end portion toward the other end portion thereof, with a light-emitting surface of each of the plurality of light emitting elements arranged so as to oppose the first side, the first side serving as a light-receiving surface;
• a light source driver that controls the plurality of light-emitting elements with respect to each of a plurality of blocks of the light-emitting elements;
• a light source substrate having the plurality of light emitting elements mounted on a first surface thereof;
• a light source support member attached to a second surface of the light source substrate;
• and
• a positioning structure located between adjacent ones of the plurality of blocks so as to place the light source substrate in position on the light source support member, with at least a part of the positioning structure exposed on the first surface of the light source substrate,
• wherein the plurality of light emitting elements are divided into aplurality of blocks in the direction from the end portion toward the other end portion of the first side, and the light source driver controls an amount of light to be emitted from each of the blocks, in accordance with a mode in which an associated display panel is driven.

A display device, comprising:

• a lighting device;
• and
• a display panel disposed to overlap a light-emitting surface of the lighting device,
• wherein the lighting device includes:
• a light guide plate disposed to overlap the display panel;
• a plurality of light emitting elements aligned along a first side of the light guide plate in a direction from an end portion toward the other end portion thereof, with a light-emitting surface of each of the plurality of light emitting elements arranged so as to oppose the first side, the first side serving as a light-receiving surface;
• a light source driver that controls the plurality of light-emitting elements with respect to each of a plurality of blocks of the light-emitting elements;
• a light source substrate having the plurality of light emitting elements mounted on a first surface thereof;
• a light source support member attached to a second surface of the light source substrate;
• and
• a positioning structure located between adjacent ones of the plurality of blocks so as to place the light source substrate in position on the light source support member, with at least a part of the positioning structure exposed on the first surface of the light source substrate, the positioning structure adapted to be inserted from the first surface of the light source substrate.

A display device, comprising:

• a lighting device;
• and
• a display panel disposed to overlap a light-emitting surface of the lighting device,
• wherein the lighting device includes:
• a light guide plate disposed to overlap the display panel;
• a plurality of light emitting elements aligned along a first side of the light guide plate in a direction from an end portion toward the other end portion thereof, with a light-emitting surface of each of the plurality of light emitting elements arranged so as to oppose the first side, the first side serving as a light-receiving surface;
• a luminance distribution detector that detects a brightness of each of a plurality of blocks of the light-emitting elements;
• a light source driver that controls, responsive to the detected brightness of each of the plurality of blocks, the plurality of light-emitting elements with respect to each of the plurality of blocks of the light-emitting elements;
• a light source substrate having the plurality of light emitting elements mounted on a first surface thereof;
• a light source support member attached to a second surface of the light source substrate;
• and
• a positioning structure located between adjacent ones of the plurality of blocks so as to place the light source substrate in position on the light source support member, with at least a part of the positioning structure exposed on the first surface of the light source substrate.
