This emission scheme is generally referred to as a binary pulse width modulation emission scheme for a sub-pixel 72 because the image data 98 is binary data selected to modulate light emission from the sub-pixel 72 in such a way as to change a perceived brightness of the sub-pixel 72. Graph 118 depicts emission periods for a sub-pixel 72 caused by the binary pulse width modulation emission scheme. With the binary pulse width modulation emission scheme, the sub-pixel 72 is operated to change a perceived brightness of light emitted through varying emission periods of light. As depicted in the graph 118, image data 98 received by the sub-pixel 72 is represented through five bits of binary data. Thus, when the image data 98 equals 01111, the sub-pixel 72 emits light corresponds to a first range 120 having emission periods 124A for the least significant bit and emission periods 124B, 124C, and 124D for subsequent bits. In this embodiment, the least significant bit of the image data 98 from memory 78 operates the switch 104 first, hence why the least significant bit corresponds to a first emission period 124A in time. As such, in between transmission of bits to operate switch 104, emission temporarily halts, as is seen with the no emission period between the first emission period 124A and the emission period 124B. In addition, when the image data 98 equals 11111, the emission period of the sub-pixel 72 corresponds to a second range 122 that is equal to the first range 120 plus a last emission period 124E corresponding to the most significant bit (e.g., because the most significant bit is now enabled as a 1).
