Problems solved by technology

However, the dependence of pixel appearance on history is still relatively large
Thus, it is difficult to have a sufficiently reproducible appearance of the pixel
[0009] The disadvantage of the described display panel is that it is difficult to obtain pixels with a sufficiently reproducible appearance by means of

Embodiment Construction

[0032] FIG. 1 shows a display panel 1 with a second substrate 9 and a plurality of pixels 2 . The pixels 2 are arranged substantially along a straight line in a two-dimensional structure, for example.

[0033] FIG. 2 shows a display panel 1 with a first substrate 8 and a second opposite substrate 9 . An electrophoretic medium 5 is present between the substrates 8 , 9 . The electrophoretic medium 5 comprises first charged particles 6 of a first color in fluid form. For example, the first charged particles 6 are black and have a negative charge, while the fluid is white. Such electrophoretic media are available from E Ink Corporation. First, second and third electrodes (3, 4, 10) are associated with each pixel (2). In this figure, a first substrate 8 has a first electrode 3 for each pixel 2 , and a second substrate 9 has a second electrode 4 and a third electrode 10 for each pixel 2 . The first, second and third electrodes 3, 4, 10 are capable of receiving first, second and...

Abstract

The electrophoretic display panel for displaying a picture and a subsequent picture, has a first and a second opposed substrate (8,9), an electrophoretic medium between the substrates (8,9), a plurality of pixels (2), a first, a second and a third electrode (3,4,10) associated with each pixel (2) and drive means. The electrophoretic medium has first charged particles having a first color. The drive means are able to control a first, a second and a third potential on the first, the second and the third electrode (3,4,10), respectively, to have picture potential values for displaying the picture, subsequently to have interval potential values before having subsequent picture potential values for displaying the subsequent picture. For the display panel to have pixels (2) with reproducible appearances, the drive means are able to apply reset potential values to the electrodes (3,4,10) as the interval potential values for bringing the charged particles into a predetermined reset position (13) between displaying the picture and displaying the subsequent picture.

Description

technical field [0001] The invention relates to an electrophoretic display panel for displaying images and subsequent images, comprising: [0002] - first and second opposing substrates; [0003] - an electrophoretic medium between said substrates, said electrophoretic medium comprising first charged particles having a first colour; [0004] - multiple pixels; [0005] - first, second and third electrodes associated with each pixel; and [0006] drive means capable of controlling the first, second and third potentials on the first, second and third electrodes, respectively, so as to have an image potential value for displaying an image, and subsequently having a subsequent image for displaying a subsequent image Potential values ​​are preceded by interval potential values. Background technique [0007] An embodiment of the type of electrophoretic display panel mentioned in the opening part is described in the non-prepublished European patent application 01200952.8 (PHNL0...
