A light emitting diode (LED) display apparatus includes first to third data lines, gate lines, a first color sub-pixel unit and second color sub-pixel units. The gate lines include (N−1)th, Nth and (N+1)th gate lines. The first color sub-pixel unit includes a first color LED electrically coupled to the first data line and the (N−1)th and Nth gate lines. When the (N−1)th or Nth gate line is enabled, the first color LED is turned on. The second color sub-pixel unit is electrically connected to the second data line, and includes a second color LED. The second color sub-pixel units are electrically coupled to the gate lines, respectively. When each gate line is enabled, the corresponding second color LED is turned on. A light emitting area of the first color sub-pixel unit is greater than a light emitting area of each second color sub-pixel unit.
