摘要： In one embodiment of the present application, a memory stores a lookup table storing, in accordance with a combination of a value of a video signal of a current frame and a value of a video signal of a previous frame, each of correction values, the correction values in each of which a temporal change of a video signal is enhanced. A correcting circuit carries out, with respect to a correction value selected from the lookup table, a predetermined correcting operation in accordance with a polarity of a voltage to be applied to each of data signal lines S1 through Sm, with the use of a correction coefficient which is set based on properties of liquid crystal. Thus found is a corrected video signal in accordance with a positive or negative polarity. This makes it possible to find, with less memory capacity, an optimum corrected video signal in accordance with a polarity of a voltage to be applied to a data signal line.

摘要： A display panel with built-in optical sensors is provided that can accurately remove a noise component in an imaging signal of an image pick-up sensor in a display region without being influenced by distance from a heat source or distance from a sensor output terminal. The display panel with built-in optical sensors has an active matrix substrate having a pixel region in which pixels are disposed in a matrix, and is configured such that optical sensors are formed in at least a portion of the pixel region. Among the optical sensors in the pixel region are image pick-up sensors (12S) and light-shielded sensors (12B) that are shielded from light. The display panel with built-in optical sensors further includes a correction circuit (4) that corrects sensor output of the image pick-up sensors (12S) with use of sensor output from the light-shielded sensors (12B).
