    Abstract: A method of driving a display device includes: sensing characteristic information of pixels by outputting sensing voltages to sensing lines; and operating an external compensation of the pixels based on the characteristic information. The sensing of the characteristic information of pixels includes: detecting a capacitance deviation of sensing capacitors of first sensing lines connected to the sensing lines; and sensing the characteristic information of the pixels by replacing at least one of the first sensing lines with a second sensing line based on the capacitance deviation.

    Abstract: A set of optical sheets may perform at least one of diffusion, refraction, and condensation of light. The set of optical sheets may include a first optical sheet that includes a first base film and a first distinction unit disposed outside the first base film. The set of optical sheets may further include a second optical sheet that includes a second base film and a second distinction unit disposed outside the second base film. The second distinction unit may be spaced from the first distinction unit in a plan view of the set of optical sheets if the second base film complete overlaps the first base film.

    Abstract: A driving unit of a display panel includes a control part, a gate driving part, a grayscale compensating part, and a data driving part. The control part provides a control signal and a grayscale signal. The gate driving part provides a gate signal to the display panel. The display panel is divided into a plurality of blocks according to a distance from a light source to each of the blocks. The grayscale compensating part outputs a compensating signal of an n-th frame using look-up tables, and the look-up tables respectively correspond to the blocks of the display panel. The data driving part converts the compensating signal of the n-th frame into a grayscale voltage and provides the grayscale voltage to the display panel. Accordingly, the driving unit of the display panel may improve a response speed of liquid crystals and display quality.

    Abstract: A light guide plate for a backlight. The light guide plate includes: a light source unit for generating light; a light guide plate proximate to the light source unit and including an upper surface and a lower surface; and a light emission pattern configured to diffuse a portion of the light directed toward an image display panel, and a first straight pattern configured to channel the light along a direction substantially parallel to a direction of propagation of the light generated by the light source unit, both the light emission pattern and the first straight pattern being disposed on one of the upper surface and the lower surface of the light guide plate, in which the first straight pattern has peaks and valleys formed in alternating and repeating manner in a direction substantially perpendicular to a direction of propagation of the light generated by the light source unit.
