Embodiment Construction

[0025] Figure 1a is a general view of a back panel pixel 105 in an active matrix back panel. The pixel area 102 constitutes an effective pixel area. The TFT region 101 , the column electrode region 103 and the row electrode region 104 also occupy space on the rear panel unit 105 . In dual metal layer designs, especially for active matrix backplanes, the effective pixel area is smaller than the total pixel area because some area is required for the row, column, and pixel TFTs.

[0026] FIG. 1 b shows an electrophoretic front panel pixel unit 106 with a microcup structure, which has a total pixel area 107 .

[0027] Figures 2a, 2b illustrate geometries in which straight walls are replaced by curved walls. The moiré effect is mitigated by introducing curved walls to create a more uniform opening. The mitigation of the moiré effect can be seen in Figures 2a and 2b.

[0028] In Fig. 2a, 30×30 cells in the front panel 210 (cell size 290×290 μm 2 ) area and rear panel (pixel siz...

Abstract

A display has reduced moire interference. The display has a backplane with a regular array of pixels and a frontplane with a regular array of cells. The backplane and frontplane are laminated together. The width of the distribution of aperture (the total inner cell area above an active pixel area divided by total pixel area) over the display is reduced. Sinusoidally curved walls or other curved pixel edges may be used in the frontplane or backplane to control the distribution.

Description

technical field [0001] The present invention relates to electronic display devices, and more particularly to displays fabricated from front and back panels in which the moiré effect is reduced or eliminated. Background technique [0002] The display is usually assembled by a rear panel and a front panel. The rear panel contains pixel electrodes and conductor arrays for driving electronic circuits to drive, and the front panel is equipped with the front panel of the electro-optical unit of the display. An electrophoretic active matrix display, for example, may comprise an active matrix back panel and an electrophoretic front panel. The front panel does not have to be electrophoretic. The front panel may have electrowetting or liquid crystal display elements or another type of photopixel element positioned relative to the electrons arrayed on the rear panel. Such a display is known, for example, from published application No. US 2004 / 0219306A by Xiaojia Wang et al., which is...
