    Abstract: A sensing circuit of a display device includes a sensing line initialization circuit which substantially simultaneously initializes a first sensing line and a second sensing line in a first sub-sensing period of a sensing period, a first line selection switch which couples the first sensing line to a sensing channel in the first sub-sensing period, a second line selection switch which couples the second sensing line to the sensing channel in a second sub-sensing period of the sensing period, and the sensing channel which samples a first sensing voltage of the first sensing line in a first sampling period of the first sub-sensing period, and samples a second sensing voltage of the second sensing line in a second sampling period of the second sub-sensing period. The second sensing line is not initialized during a period from the first sampling period to the second sampling period.

    Abstract: A scan driver includes a first transistor including gate, first, and second electrodes coupled to a Q node, a scan clock line, and a scan line. A second transistor includes gate and first electrodes coupled to a scan carry line, and a second electrode coupled to the Q node. A third transistor includes gate and first electrodes coupled to a first control line and a sensing carry line. A fourth transistor includes a gate and first electrode coupled to the sensing carry line and the third transistor first electrode. A fifth transistor includes gate, first, and second electrodes coupled to a fourth transistor second electrode, a second control line, and a node. A capacitor includes first and second electrodes coupled to the fifth transistor first and gate electrodes. A sixth transistor includes gate, first, and second electrodes coupled to a third control line, the node, and the Q node.

    IPC: G02B27/01

    Abstract: A display device includes a display unit including a first surface emitting first light, a second surface opposite to the first surface, a first transmission area transmitting light incident on the first surface, and a second transmission area transmitting the light incident on the first surface. The display device includes a first lens on the first surface and including a first hole overlapping the first transmission area in a thickness direction, a second lens on the first surface and spaced apart from the first lens and including a second hole overlapping the second transmission area in the thickness direction, and light sources emitting second light and disposed on the first and second lenses. The display device includes a first camera sensor on the second surface and overlapping the first transmission area, and a second camera sensor on the second surface and overlapping the second transmission area.

    IPC: H10K59/38

    Abstract: A color conversion panel includes an active area corresponding to a display area and including an active pixel portion at which light is emitted, a dummy area adjacent to the active area and including a first dummy pixel portion and a second dummy pixel portion, and a color conversion layer including a bank layer in both the active area and the dummy area. The bank layer defines each of an active opening corresponding to the active pixel portion and defining an active opening planar area, a first dummy opening corresponding to the first dummy pixel portion and defining a first planar area, and a second dummy opening corresponding to the second dummy pixel portion and defining a second planar area. The first planar area of the first dummy opening is different from the second planar area of the second dummy opening.
