Display module and display apparatus including the same

A display apparatus comprising:

• a housing;
• and
• a plurality of display modules mounted in the housing,
• wherein each of the plurality of display modules comprises:
• a module substrate,
• a plurality of pixels arranged provided on an upper surface of the module substrate, and
• a plurality of micro pixel controllers, each of the plurality of micro pixel controllers being configured to control at least two pixels among the plurality of pixels and being provided in a space between the at least two pixels on the upper surface of the module substrate,
• wherein at least one of the plurality of micro pixel controllers comprises a slope waveform generator configured to control a brightness of each of the at least two pixels by:
• generating a slope waveform;
• and
• inputting the generated slope waveform to each of the at least two pixels.

A display apparatus comprising:

• a plurality of display modules;
• and
• a timing controller configured to transmit image data and a timing control signal to the plurality of display modules,
• wherein each of the plurality of display modules comprises:
• a module substrate,
• a plurality of inorganic light-emitting elements provided on an upper surface of the module substrate, and
• a plurality of micro pixel controllers, each of the plurality of micro pixel controllers being configured to control an amplitude and a pulse width of a driving current applied to at least two inorganic light-emitting elements among the plurality of inorganic light-emitting elements and being provided in a space between the at least two inorganic light-emitting elements,
• wherein at least one of the plurality of micro pixel controllers comprises a slope waveform generator configured to control the pulse width of the driving current by:
• generating a slope waveform;
• and
• inputting the generated slope waveform to each of the at least two pixels.

A method of a display module, the method comprising:

• controlling, with a micro pixel controller, two or more pixels arranged on an upper surface of a module substrate of the display module, the micro pixel controller being disposed in a space between the two or more pixels;
• generating, with a slope waveform generator of the micro pixel controller, a slope waveform;
• and
• controlling, with the micro pixel controller, a brightness of the two or more pixels based on the generated slope waveform by inputting the generated slope waveform to each of the at least two pixels.
