<p>The head has a sensor (8) detecting luminance and/or color value of light of a light source, and a screen (6), where an acquisition field of the sensor is formed in square-shape. The screen narrows the light incidence angle to the sensor, where a cross section of the screen is adjusted to the cross section of the field such that light rays radiated by a liquid crystal display (LCD) module are completely detected by the sensor. An independent claim is also included for a luminance and/or chroma measuring device comprising a measuring head.</p> |
