Abstract: A hybrid display system for a device includes a high resolution display and a low resolution display that are positioned relative to each other to display an image having mixed resolution. A single high resolution display having a size of 1.5 cm by 10 cm and a first cost may be replaced by a hybrid display having the same overall size but using a smaller size (e.g., 1.5 cm by 4 cm) and lower cost for the high resolution display. To achieve the remaining 6 cm in display size, the low resolution display may have a size of approximately 1.5 cm by 6 cm and a lower cost than either of the high resolution displays, such that a combined cost of the high and low resolution displays in the hybrid display makes the second cost lower than the first cost. The high and low resolution displays may use different display technologies to achieve cost and size tradeoffs.
