A display device includes: a display panel configured to display an image; an input sensing substrate on the display panel; a flexible circuit film coupled to one side of an upper surface of the input sensing substrate; a step compensation film spaced apart from the flexible circuit film on the upper surface of the input sensing substrate; and an anti-reflection film on the flexible circuit film and the step compensation film, wherein the step compensation film comprises: a compensation layer on the upper surface of the input sensing substrate, and an overcoat layer between the compensation layer and the input sensing substrate.

Display device and method for manufacturing same

An electronic device includes a display panel. A touch panel is disposed on the display panel. A printed circuit film is electrically connected to the touch panel and includes a first portion having a first thickness, and a second portion having a second thickness greater than the first thickness. A boundary between the first portion and the second portion overlaps the touch panel in a thickness direction of the touch panel and at least a portion of the second portion contacts the touch panel.

Electronic device

A backlight unit includes a plurality of light source groups each including a plurality of light source units which generate light. The backlight unit further includes a light source substrate on which the light source groups are disposed and a plurality of light source drivers connected to the light source substrate to drive the light source groups. The light source substrate includes a first extension portion extended in a first direction. The light source units are disposed on the first extension portion. The light source substrate further includes a plurality of second extension portions extended from the first extension portion in a second direction crossing the first direction and a plurality of third extension portions extended from ends of the second extension portions in the first direction. The light source drivers are connected to the third extension portions to drive the light source groups.

Backlight unit and display apparatus including the same

A display device including a plurality of source drivers. Each of the .plurality of source drives may include a register storing information on a bias voltage provided from the outside; a gamma voltage generation unit receiving at least one reference gamma voltage and generating a plurality of gamma voltages according to the reference gamma voltage; and an output buffer including a plurality of source amplifiers driven by the bias voltage and receiving the plurality of gamma voltages. The gamma voltage generation unit may adjust a level of at lest one of the at least one reference gamma voltage, according to a bias voltage having the lowest level among bias voltages provided to respective source drivers.
