An electronic device comprises at least one static induction transistor () and at least one thin film transistor (). The static induction transistor () has a first channel () of a semi conducting material extending between a first main electrode () and a second main electrode () through a first and a second insulating layer (), and has a first control electrode () surrounding the first channel and extending between the first and the second insulating layer. The thin film transistor () has a third main electrode () and a fourth main electrode () coupled by a second channel () of a semi conducting material and a second control electrode (). At least one of the first and the second insulating layer functions as a dielectric layer between the second control electrode and the second channel.

Electronic device comprising static induction transistor and thin film transistor, method of manufacturing an electronic device and display panel

The invention relates to a display structure comprising an electrode layer () superposed on a sub-layer () wherein a surface of the sub-layer facing the electrode layer is roughened. In particular, the display structure may relate to a TFT stack comprising a layer of an electrode metal corresponding to a pixel electrode (). The pixel pad together with the data line () is used for charging of the pixel pad. The gate electrode () used is separated from the source and drain electrode () by a dielectric layer (). The structural layers of the TFT may be deposited on a suitable flexible substrate (). In order to prevent defects in the light modulating layer () from being visible, a surface of the sub-layer () underlying the electrode layer () is roughened. It is desirable to provide such improvement to, among others, electrophoretic-type displays and liquid crystal-type displays.

Display structure with a roughened sub-electrode layer

A display structure is described comprising a displaying medium, a backplane provided with an active matrix and a pixel pad comprising a plurality of pixels having an inter-pixel spacing, said pixel pad superposing the active matrix, wherein the inter-pixel spacing is in the range of 2.5-40 micrometers, preferably in the range of 8-20 micrometers.
