ACTIVE MATRIX ELECTROLUMINESCENT DISPLAY DEVICE

摘要

An active matrix electroluminescent (EL) display device comprises a matrix array of display cells (10) arranged in rows and columns, each cell comprising an EL display element (20) and driving circuitry. The cells are arranged in groups (12) which may constitute pixels. Each group of cells forms a series arrangement arranged so a data signal applied to the first cell in a series arrangement, via an associated data line (14), can be transferred to a neighbouring cell in the same group, and so on for subsequent cells in the group, upon application of a control signal applied to an associated control line (15). This device enables a digital drive scheme to be implemented. The provision of grouped display cells arranged so as to be driven in this way enables a grey scale to be implemented using fewer data lines (14) than usual.
