Display device and input system including the same

A display device comprising:

• a display part comprising a light emitting element disposed in a plurality of emission areas to emit light;
• a plurality of touch electrodes disposed in a light blocking area surrounding the plurality of emission areas on the display part to sense a touch;
• a first light blocking part disposed in the light blocking area on the plurality of touch electrodes;
• a second light blocking part disposed on a part of the first light blocking part;
• and
• a plurality of code patterns determined by a planar shape of the second light blocking part, wherein
• the first light blocking part comprises one of an inorganic black pigment and an organic black pigment,
• the second light blocking part comprises the other of the inorganic black pigment and the organic black pigment, and
• the plurality of code patterns have position information according to a distance between the plurality of code patterns and a planar shape.

An input system comprising:

• a display device that displays an image;
• and
• an input device that inputs a touch into the display device, wherein
• the display device comprises:
• a display part comprising a light emitting element disposed in a plurality of emission areas to emit light;
• a plurality of touch electrodes disposed in a light blocking area surrounding the plurality of emission areas on the display part to sense a touch;
• a first light blocking part disposed in a part of the light blocking area on the plurality of touch electrodes;
• a second light blocking part disposed in another part of the light blocking area on the plurality of touch electrodes;
• and
• a code pattern determined by a planar shape of the second light blocking part to have position information,
• the first light blocking part comprises one of an inorganic black pigment and an organic black pigment,
• the second light blocking part comprises another one of the inorganic black pigment and the organic black pigment, and
• the input device photographs the code pattern, converts the code pattern into a preset data code, and transmits coordinate data composed of the data codes to the display device.
