Abstract

Disclosed is a technique for increasing the aperture ratio pixel circuits of the calibration techniques in active matrix light emitting displays, in particular, active matrix organic light emitting diode (AMOLED) displays. The technique includes a new pixel circuits and a novel floor-planning for layout.

Description

FIELD OF THE INVENTION

The present invention generally relates to a light emitting device displays, and particularly, to a technique for AMOLED that increases the aperture ratio of the pixel by sharing the calibration component..

SUMMARY OF INVENTION
Disclosed technique shares the calibration switches without affecting the pixel circuit operation and without adding extra controlling signal.

Advantages The aperture ratio increases and so the lifetime, resolution and luminance can increase. Also, the number of signals connected to the panel is reduced significantly and so the implementation cost of the external driver decreases.

FIG. 1 shows a general embodiment of the new driving scheme.
FIG. 2 shows a RGBW structure based on the new pixel circuit.
FIG. 3 shows the proposed layout.

FIG. 1 shows a general embodiment of new driving scheme. The transistor in this circuit can be based on amorphous silicon, poly silicon, CMOS, and organic technologies.
Also, one can change any of this transistor to PMOS using complementary circuit concept.
Here the pixel in one column are divided to few segments (each segments has 'h' number of pixels). In FIG.1 (a), the pixel is programmed through the data line, DATA[j], and the acquisition data is read back through DATA [j+l] (or DATA [j-1]). The sensing switches, TS, grantees a conflict free readout and programming procedures.

FIG. 2 shows a segment with two pixels and RGBW structure. Here, the sensing TFT, TWB and TGR, of adjacent segment which using the same select line is put in this segment area to reduce the layout complexity.

FIG. 3 shows the layout for the pixel circuits of FIG. 2.
