Abstract
A modular display apparatus having a plurality of sub-screens including sensors; a plurality of pixels; and processors configured to: acquire an electric energy of the plurality of pixels based on voltages across light emitting diodes of the plurality of first pixels; and operate in a dehumidification mode based on humidity information acquired from the sensors being greater than or equal to a predetermined threshold. The operating in the dehumidification mode include controlling one or more of a driving time of the light emitting diodes and a voltage of cathodes of the light emitting diodes such that an average value of the electric energy is held at a predetermined value.
Claims19
A modular display apparatus comprising a plurality of sub-screens comprising a first sub-screen, the first sub-screen comprising:
- a first sensor;
- a first display module comprising a plurality of first pixels;
- and
- a first processor configured to:
- acquire a first electric energy of the plurality of first pixels based on voltages across first light emitting diodes of the plurality of first pixels;
- and
- operate in a dehumidification mode based on humidity information acquired from the first sensor being greater than or equal to a predetermined threshold,
- wherein operating in the dehumidification mode comprises controlling one or more of a driving time of the first light emitting diodes and a voltage of cathodes of the first light emitting diodes such that an average value of the first electric energy is held at a predetermined value.
A method for controlling a modular display apparatus, the modular display apparatus including a sensor and a plurality of light emitting diodes, the method comprising:
- operating in a dehumidification mode based on humidity information acquired from the sensor being greater than or equal to a predetermined threshold;
- and
- controlling, while operating in the dehumidification mode, one or more of a driving time of the plurality of light emitting diodes and a voltage of cathodes of the plurality of light emitting diodes such that an average value of an electric energy acquired based on a voltage across the plurality of light emitting diodes is held at a predetermined value.
