    Abstract: A display panel includes a plurality of pixels arranged in an array; a plurality of first sensor units (2) in the array, each first sensor unit (2) being coupled to at least one of the plurality of pixels and being configured to detect brightness of the at least one of the plurality of pixels; and a plurality of second sensor units (3) in the array, each second sensor unit (3) being coupled to at least one of the plurality of first sensor units (2) and being configured to detect a variation in at least one environmental parameter of the at least one of the plurality of pixels. Each first sensor unit (2) includes a first photo sensor (S1). Each second sensor unit (3) comprises a second photo sensor (S2) and a shielding layer on a light-receiving surface of the second photo sensor (S2).

    Abstract: A pressure detecting circuit may include a pressure sensing circuit (101), a signal generating circuit (102), and a frequency detecting circuit (103). The pressure sensing circuit (101) and the signal generating circuit (102) may be configured to constitute an oscillating circuit (104). The signal generating circuit (102) may be configured to generate an oscillating signal based on a pressure sensed by the pressure sensing circuit (101). The frequency detecting circuit (103) may be configured to detect a frequency of the oscillating signal and determine a value of the pressure sensed by the pressure sensing circuit (101) based on the frequency of the oscillating signal.
