ELECTROLUMINESCENT DISPLAY WITH INTERLEAVED 3T1C COMPENSATION
摘要
<p>A method of compensating for changes in the characteristics of transistors and EL devices in an EL display, includes providing an EL display having a two-dimensional array of EL devices arranged in rows and columns, wherein each EL device is driven by a drive circuit in response to a drive signal; providing a first drive circuit for an EL device having three transistors and providing a second drive circuit for an EL device having only two transistors, and wherein a first column in the display includes at least one first drive circuit and an adjacent second column includes at least one second drive circuit; deriving a correction signal based on the characteristics of a transistor in a first drive circuit, or the EL device; and using the correction signal to adjust the drive signals applied to the first drive circuit and one or more adjacent second drive circuits.</p>
