Abstract: Embodiments provide a quantum dot that includes a core including zinc (Zn), tin (Sn) and phosphorus (P), and a shell surrounding the core, wherein a molar ratio of a number of moles of zinc to a number of moles of tin is in a range of about 0.1 to about 2. The quantum dots have high luminous efficiency and color purity.

Abstract: A quantum dot includes a core including InP, a first shell around (e.g., surrounding) the core and including ZnTeSe, a second shell around (e.g., surrounding) the first shell and including ZnSe, and a third shell around (e.g., surrounding) the second shell and including ZnS, wherein the ratio of the number of moles of the Te in the first shell to the number of moles of the P in the core is about 0.02 to about 0.90.

Abstract: A method of driving a display device including driving a display panel including a sensing area defined above a fingerprint sensor in an initial mode, driving the sensing area in a first color pattern and a second color pattern having a color different from a color of the first color pattern, sensing a fingerprint through the fingerprint sensor that receives a light reflected by the fingerprint when the fingerprint is adjacent to the sensing area, determining whether the sensed fingerprint is a duplicate fingerprint, and performing a user authentication mode when the sensed fingerprint is a normal fingerprint. The first color pattern has a light transmittance higher than a light transmittance of the second color pattern.

Abstract: A display device includes a display panel to display an image; an input sensor disposed on the display panel; a flexible circuit board attached to the input sensor; a compensation film disposed on the input sensor and spaced apart from the flexible circuit board; and an anti-reflector disposed on the flexible circuit board and the compensation film. The compensation film has a thickness is greater than that of the flexible circuit board and less than or equal to a distance between the anti-reflector and the input sensor.
