A display device includes: a display panel; a circuit board disposed on a lower surface of the display panel; and an adhesive layer disposed between the circuit board and the lower surface of the display panel. An area of the circuit board that has a roughness higher than a predetermined reference roughness does not overlap the adhesive layer.

Display device

A display apparatus includes a display panel, a backlight unit, a backlight control circuit, sensors, a read-out circuit and a sensor auxiliary circuit. The display panel includes pixels and displays an image. The backlight unit includes a first light source which emits a first light in a infrared light range. The backlight control circuit controls a brightness of the first light source. The sensors sense an external signal and outputs first sensing signals. The read-out circuit outputs the first sensing signals as second sensing signals. The sensor auxiliary circuit compares a maximum value and a minimum value of the second sensing signals and provides a brightness control signal to the backlight control circuit based on the compared difference to control the brightness of the first light source.

Display apparatus and method of driving the same

In a display apparatus, a first substrate includes a plurality of pixels and a plurality of first signal lines connected to the pixels. A second substrate includes a plurality of sensors and a plurality of second signal lines connected to the sensors and extended in a direction in which the first signal lines are extended. Each of the second signal lines is disposed between two first signal lines adjacent to each other and disposed closer to a center line, which divides an area between the two first signal lines into two portions, than the two first signal lines. Thus, signal interference between the first and second signal lines may be reduced, thereby preventing mis-operation or malfunction of the display apparatus.
