SPARKLE DISPLAY
First Claim
1. A hybrid display system, comprising:
- a first array of light emitting pixels spaced apart from one another by a first pitch;
a second array of light emitting pixels spaced apart from one another by a second pitch;
a third array of light emitting pixels spaced apart from one another by a third pitch, the second and third arrays are positioned adjacent to opposite sides of the first array,the first pitch is smaller than the second and third pitches and the first array includes a first pixel density that is higher than a pixel density of the second and third arrays, the light emitting pixels of the first, second and third arrays have pixels sizes that are approximately equal;
an optical stack includinga diffuser positioned above the first, second and third arrays and having a uniform thickness profile across the first array and a variable thickness profile across the second and third arrays; and
display driver circuitry electrically coupled with the first, second and third arrays and operative to receive control and image data signals for generating an image from light emitted by the light emitting pixels.

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.
