摘要： A liquid crystal panel with built-in sensors 11 includes, in a pixel array 17, a plurality of pixels 1 and a plurality of optical sensors 2 which are arranged in a row direction and a column direction. The optical sensors 2 are provided to be associated with pixels 1 in every other row (e.g., to be associated with pixels 1 in even rows). A panel drive circuit 16 performs one-line inversion drive and reads signals based on the amounts of received light, from the optical sensors 2. Since the outputs from the optical sensors 2 change in the same direction due to the influence of display data, stripe noise resulting from the switching of the polarities of voltages written into pixel circuits 3 is prevented from occurring in an image generated based on the outputs from the optical sensors 2.

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).
