PHOTOSENSITIVE DEVICE AND DISPLAY DEVICE FOR DISPLAYING Russian patent published in 2018 - IPC G09G3/36 

FIELD: measuring equipment.

SUBSTANCE: invention relates to photosensitive devices measuring brightness, color grade and other parameters in displays. Device comprises body frame disposed in a frame around the display panel for displaying; photosensitive element used to measure the brightness and/or color grade of the display panel for displaying; sensor unit providing the possibility of receiving the light by the photosensitive element; guide member configured to direct the sensor unit and located adjacent to the sensor unit; and a driving means configured to move the sensor unit. Photosensitive element and sensor unit are located in the frame. Sensor unit is movable to the measurement area on the display screen of the display panel for displaying by a first rotation operation until the sensor unit is directed by the guide member. After the sensor unit is guided by the guide member, the sensor unit allows approximating to the display screen by a second rotation operation in the direction perpendicular to the direction of the first rotation operation.

EFFECT: photosensitive device and display device for displaying are proposed.
