Pixel structure of a sunlight readable display
A display that is readable under direct sunlight comprises a half organic light emitting diode structure and a half reflective liquid crystal display structure. It uses a thin film transistor as a switch to solve the problem of crosstalk between the organic light emitting diode mode and the liquid crystal mode as well as the dc residual problem and has the advantages of both display structures. The data signals in organic light emitting diode mode and liquid crystal mode are controlled by different control systems. By properly selecting liquid crystal material and organic light emitting diode material such that the ranges of the data signals are similar, one data driver can be shared between the two modes.
