Problems solved by technology

Therefore, this wiring part cannot be used as a light-emitting area
Moreover, each pixel is provided with a selection thin film transistor that is turned on and off by a selection line to supply the voltage of the data line to the storage capacitor, and a drive current corresponding to the voltage held in the storage capacitor is provided to the organic EL element by the power supply line. Drive the thin film transistor, so the part where the thin film transistor is configured cannot be used as a light emitting area
Therefore, there is a problem of reducing the aperture ratio

Embodiment Construction

[0014] Embodiment of the present invention is described now in conjunction with accompanying drawing:

[0015] figure 1 It is a typical schematic diagram of plane composition according to an embodiment of the present invention. One data line DL is provided for each pixel column, but two data lines are provided every other pixel column. And the power line PL is arranged between the pixel columns not provided with the data line DL. And the gate line GL is arranged between each pixel row.

[0016] Each pixel is provided with: a selection thin film transistor 1 , a driving thin film transistor 2 , a storage capacitor 3 and an organic electroluminescence component 4 . The selected thin film transistor 1 is a P-channel thin film transistor in this example, the source is connected to the data line DL, the drain is connected to the gate of the driving thin film transistor 2, and the gate is connected to the gate line GL. The driving thin film transistor 2 is a P-channel thin film ...

Abstract

Organic EL panel. To increase an aperture ratio of an organic EL panel. Pixels of four colors of R, G, B and W are each arranged in a stripe-like shape. Data lines DL are arranged between alternate pixels two lines apiece; and power lines PL are arranged one line apiece between the pixels where no data lines DL are arranged. One of a pair of the pixel lines sharing one of the power lines PL is used for a color having the best current efficiency and the other is used for a color having the worst current efficiency. A pair of the pixel lines sharing the other of the power lines PL are used as ones for two colors having intermediate current efficiencies.

Description

technical field [0001] The invention relates to a strip-type organic electroluminescent panel that at least includes organic electroluminescent components that emit light in three specific colors and arranges pixels of the same color in a matrix in the column direction. Background technique [0002] In the past, the organic electroluminescence (EL) display was regarded as one of the second-generation flat-panel displays to replace the liquid crystal display device and attracted much attention. In this panel, the luminous color of each pixel can be determined by changing the light-emitting material of the organic light-emitting layer used for each pixel. Therefore, it is possible to realize RGB display with the emission color of each pixel being different. [0003] In the organic EL panel as described above, in order to realize bright display, the amount of current supplied to each organic EL element can be increased. However, when the amount of current is increased, there ...
