Abstract: An apparatus is disclosed. In some examples, the apparatus comprises a display panel comprising a plurality of display pixels. In some examples, the apparatus comprises a plurality of temperature sensors disposed at different portions the display panel, wherein the plurality of temperature sensors comprise ratioed pairs of thin film transistors and the ratioed pairs of thin film transistors are formed on the display panel. In some examples, the apparatus comprises control circuitry for changing illumination properties of the plurality of display pixels based on changes is temperature detected by a proximate temperature sensor of the plurality of temperature sensors. In some examples, the ratioed pairs of thin film transistors are operated in a sub-threshold mode.
