Abstract: A touch sensor includes first electrodes extending in a first direction, second electrodes spaced apart from the first electrodes and extending in a second direction to cross the first electrodes, at least one pressure sensor arranged at an intersection between at least one of the first electrodes and at least one of the second electrodes, and a sensor controller electrically connected to the first electrodes, the second electrodes, and the pressure sensor. The sensor controller is configured to detect a variation in capacitance between the first electrodes and the second electrodes to sense a touch position during a first period and detect a variation in capacitance between the at least one of the first electrodes or the at least one of the second electrodes and the pressure sensor to sense a touch pressure during a second period.

Abstract: A polarizer includes a reflective polarizer main body and an Rth compensation layer. The reflective polarizer main body includes a repetitively laminated structure, the repetitively laminated structure including two layers of different refractive indices repetitively disposed on one another. The Rth phase compensation layer is disposed at one side of the reflective polarizer main body. The Rth phase compensation layer is configured to compensate for a phase difference in an Rth direction.

Abstract: A device and method for detecting touch delay time are disclosed. In one aspect, the device includes an event driver and a delay time measurement module. The event driver is configured to receive an interrupt signal generated by a touch on a touch screen panel, process a first system count value at a time when the interrupt signal is received as an interrupt generation time, and schedule a task corresponding to the interrupt signal. The delay time measurement module is configured to process a second system count value at a time when a task execution signal is transmitted to an application module as an application execution time, and calculate the touch delay time based on the difference between the interrupt generation time and the application execution time.
