摘要： A display device includes glasses disposed to correspond to a display area of a lens. A display panel emits display light. A reflective member reflects the display light emitted from the display panel in a direction towards the glasses. A light source unit emits near-infrared light towards a user's eyes for tracking a user's eyes. A protective filter includes a liquid crystal layer. The protective filter blocks a portion of a light path of the near-infrared light emitted towards the user's eyes from the light source unit. A processor controls the liquid crystal layer. The liquid crystal layer forms a blocking area blocking the portion of the light path of the near-infrared light emitted towards the user's eyes and a transmission area that does not block the light path of the near-infrared light emitted towards the user's eyes.

摘要： A scan signal driver includes: stages to sequentially output scan signals in an active period, and to selectively output sensing signals in a vertical blank period. At least one of the stages includes: a sensing control circuit to supply a gate-on voltage to a sensing control node in response to a holding control signal during the active period, and to output the gate-on voltage of the sensing control node in response to a selectively input line select signal during the vertical blank period; an output node control circuit to supply the gate-on voltage to a pull-up node when the gate-on voltage of the sensing control node is output during the vertical blank period; and an output circuit to output a scan clock signal as a sensing signal to one of scan signal lines when the gate-on voltage is supplied to the pull-up node during the vertical blank period.

摘要： A scan signal driving unit capable of reducing the RC delay of scan control lines in an ultra-high resolution display, such as 8K UHD. The scan signal driving unit includes a plurality of stages configured to sequentially output scan signals, first clock lines to which first clock signals are applied, and second clock lines to which second clock signals are applied. Each of the first clock lines includes a (1-1)-th metal pattern and a (1-2)-th metal pattern disposed on the (1-1)-th metal pattern. Each of the second clock lines includes a (2-1)-th metal pattern disposed on the same layer as one of the (1-1)-th metal pattern and the (1-2)-th metal pattern.
