    摘要: A display system includes a source device and a sink device. The source device generates red-color display data, green-color display data, and blue-color display data and transmits first packet data including the red-color display data and a red-color display reference gamma-set, second packet data including the green-color display data and a green-color display reference gamma-set, and third packet data including the blue-color display data and a blue-color display reference gamma-set. The sink device converts the red-color display data, the green-color display data, and the blue-color display data into red-color display data-voltages, green-color display data-voltages, and blue-color display data-voltages and displays an image using the red-color display data-voltages, the green-color display data-voltages, and the blue-color display data-voltages. The sink device generates red-color display gamma-voltages, green-color display gamma-voltages, and blue-color display gamma-voltages based on the red-color display reference gamma-set, the green-color display reference gamma-set, and the blue-color display reference gamma-set, respectively.

    摘要: A display device includes a display panel, a plurality of sensors, a signal control unit, and a backlight unit. A plurality of dimming regions is defined in the display panel. The signal control unit determines a plurality of representative luminance values corresponding to the plurality of dimming regions based on image data signals received from an external device and illuminance values of an external light measured by the plurality of sensors. The backlight unit provides lights having the representative luminance values to the display panel.

    摘要: A display device includes a display panel, an accommodating member including a bottom portion and a sidewall extending from the bottom portion, a backlight unit including a light source inside the accommodating member and a light source substrate inside the accommodating member and on which the light source is mounted, and a driving substrate connected to the light source substrate disposed inside the accommodating member. The driving substrate includes a first extending portion disposed outside the accommodating member, a second extending portion extended from the first extending portion and through the sidewall of the accommodating member to dispose an end portion of the second extending portion inside the accommodating member, and a pad portion disposed on a lower surface of the end portion of the second extending portion and inside the accommodating member. The pad portion is electrically connected to the light source substrate disposed inside the accommodating member.
