Abstract: A display apparatus includes a timing controller for converting data values of black image signals to have one polarity with respect to a common voltage and for converting data values of low gray scale image signals to have one polarity with respect to the common voltage, a data driver for converting the image signals outputted from the timing controller into data voltages, and a plurality of pixels for receiving the data voltages in response to gate signals to display an image. The low gray scale image signals displays a gray scale equal to or less than a reference gray scale at a surrounding temperature lower than a reference temperature.

Abstract: In a photo alignment method, a substrate and a mask are aligned so that the substrate is spaced apart from the mask by a predetermined gap. An organic layer is formed on the substrate. The mask has a transmission portion and a light blocking portion. Light is irradiated through the mask in a direction substantially parallel with an interface between the transmission portion and the light blocking portion of the mask. Polymer chains are formed on an upper portion of the organic layer. The polymer chains are aligned in an alignment direction toward an incident direction of the light. Locations of the substrate and the mask are sensed in real time. The mask is transported to a predetermined location with respect to the substrate based on the sensed locations of the substrate and the mask.
