DISPLAY PANEL WITH BUILT-IN OPTICAL SENSORS AND DISPLAY DEVICE BASED ON SAID PANEL Russian patent published in 2012 - IPC G06F3/41 G06F3/42 

FIELD: information technology.

SUBSTANCE: display panel with built-in optical sensors has an active matrix substrate, having a pixel region in which pixels are arranged into a matrix and is configured such that optical sensors are formed at least in part of the pixel region. Among optical sensors lying in the pixel region, there image capturing sensors (12S) and light-protected sensors (12B). The display panel with built-in optical sensors further contains a correction circuit (4), which corrects the output signal of the image capturing sensors (12S) using the output signal of the light-protected sensors (12B).

EFFECT: high accuracy of eliminating the noise component in the image signal from the image capturing sensor in the pixel region without being affected by the distance from a heat source or distance from the output contact of the sensor.
