Definitions

  • This invention relates to an autostereoscopic display device with a display panel having an array of display pixels, and an arrangement for directing different views to different physical locations.
  • a known autostereoscopic display device is described in GB 2196166 A.
  • This known device comprises a two dimensional emissive liquid crystal display panel having a row and column array of display pixels acting as an image forming means to produce a display.
  • An array of elongate lenticular lenses extending parallel to one another overlies the display pixel array and acts as a view forming means. Outputs from the display pixels are projected through these lenticular lenses, which function to modify the directions of the outputs.
  • the lenticular lenses are provided as a sheet of elements, each of which comprises an elongate semi-cylindrical lens element.
  • the lenticular lenses extend in the column direction of the display panel, with each lenticular lens overlying a respective group of two or more adjacent columns of display pixels.
  • each lenticular lens is associated with two columns of display pixels
  • the display pixels in each column provide a vertical slice of a respective two dimensional sub-image.
  • the lenticular sheet projects these two slices, and corresponding slices from the display pixel columns associated with the other lenticular lenses, to the left and right eyes of a user positioned in front of the sheet, so that the user observes a single stereoscopic image.
  • each lenticular lens is associated with a group of three or more adjacent display pixels in the row direction. Corresponding columns of display pixels in each group are arranged appropriately to provide a vertical slice from a respective two dimensional sub-image. As a user's head is moved from left to right a series of successive, different, stereoscopic views are observed creating, for example, a look-around impression.
  • the above described autostereoscopic display device produces a display having good levels of brightness.
  • one problem associated with the device is that the views projected by the lenticular sheet are separated by dark zones caused by "imaging" of the non-emitting black matrix which typically defines the display pixel array.
  • display panels are based on a matrix of pixels that are square in shape. In order to generate images in colour, the pixels are divided into sub-pixels.
  • each pixel is divided into 3 sub-pixels, transmitting or emitting red (R), green (G) and blue (B) light, respectively.
  • Sub-pixels of equal colour are typically arranged in columns.
  • an autostereoscopic display device comprising:
  • a display having an array of display pixel elements for producing a display, wherein one or more adjacent display elements together from a display pixel such that an array of pixels is defined, wherein the display pixels are arranged generally in rows and columns;
  • a lenticular array arranged in registration with the display for projecting a plurality of views towards a user in different directions, and comprising lenticular lenses to focus outputs of groups of the display pixels into the plurality of views projected towards a user in different directions, thereby enabling autostereoscopic imaging
  • centroids of the display pixels define a grid of points in rows and columns, wherein the rows and columns are non-orthogonal.
  • the grid of points having non-orthogonal rows and columns is such that there is no orthogonal pair of lines with pass through all pixels centres in a row (i.e. through a number of pixels corresponding to the number or columns) and through all pixel centres in a column (i.e. through a number of pixels corresponding to the number of rows). It is of course possible to pick non-orthogonal lines even in a square grid of points, and arbitrarily name these "rows” and "columns”.
  • the grid of points in the pixel layout of the invention is not a square or rectangular grid of points - if a pair of orthogonal row and column lines are selected, one of these lines will skip pixel elements.
  • display pixel is meant the emission area of the pixel.
  • the arrangement of the invention means that a standard lenticular design can be used, and the pixel layout can be selected to optimise the optical performance depending on the sub-pixel layout.
  • a set of three or more display pixel elements can together define a colour pixel.
  • each pixel can comprise four columns of pixels elements and two rows of pixels elements, each row having red, green, blue and white pixel elements. This can define an RGBW pixel layout for example.
  • Each pixel can comprises three columns of pixel elements of red green and blue and one row of pixel elements. This defines an RGB pixel layout.
  • the display pixels define a rectangular display area, and preferably the rows of points are parallel to the top and bottom edges of the display area, and the columns of points are at an acute angle to the side edges of the display area.
  • the staggered pixel layout provides (or contributes to) the desired slant between the lens elements and the columns of pixels.
  • An array of row and column conductors is preferably provided, and the column conductors extend generally parallel to the side edges of the display area but with a stepped sawtooth shape. This sawtooth shape jumps between adjacent columns at each tooth step, and the ramp part of the sawtooth follows the direction of the pixel column.
  • the separation between the centroid of the pixel and the centroid of the drive electronics for the pixel is not equal for all pixels.
  • the drive electronics can be formed in a regular grid connected by straight orthogonal row and column lines, and the slanted columns (or rows) of pixel emission areas connect to the associated drive electronics by spur conductors.
  • the separation between the centroid of the drive electronics for a pixel and the associated crossing point of the rows and columns is not equal for all pixels.
  • the column conductors can comprise a main line which extends parallel to the side edges of the display and the spurs can extend in the row direction to the pixel elements, the spurs having different lengths to different pixel elements depending on the relative position of the pixel element and main line.
  • the lenticular lenses can have a long axis which is parallel to the sides of the display area, so that all of the desired slant is provided by the pixel array. This enables standardised non-slanted lenses to be used.
  • the lenticular lenses can instead have a long axis which is slanted with respect to the sides of the display area.
  • the slant is then provided by the combination of the lens angle and the pixel configuration.
  • the display preferably comprises an electroluminescent display device, such as an OLED device. If a top emitting OLED device is used, it becomes particularly easy to implement the desired row and column conductor patterns without reducing pixel aperture or introducing visible non-uniformities into the pixel structure.

  • the panel 3 comprises a pair of spaced transparent glass substrates, between which an aligned twisted nematic or other liquid crystal material is provided.

  • Each pixel of the display panel 3 is driven with information for one specific view.
  • the above described autostereoscopic display device produces a display having good levels of brightness. It is well known to slant the lenticular lenses at an acute angle relative to the column direction of the display pixel array. This enables an improved brightness uniformity and also brings the horizontal and vertical resolutions closer together.
  • Fig. 3 shows the native pixel layout of the 2D display panel as well as, on the same scale, the pixel layout in a 3D view obtained by putting a lenticular in front of the panel.
  • the 3D image has a repeating pattern of sub-pixels, and the colours of a few sub-pixels (R, G and B) are shown so that all colours in the pattern can be understood.

  • the resolution of the single 3D image of the pair is 1/9 of the resolution of the native display.
  • the slant angle of the lenticular as well as its pitch should be chosen such that a number of requirements are fulfilled as much as possible:
  • each of the 3D views the sub-pixels of each colour should be distributed in a pattern that is regular and having a resolution that is similar for the horizontal and vertical direction.
  • the horizontal distance between neighbouring green pixels (labelled A in Fig. 3) should be comparable to the vertical distance between neighbouring green pixels (labelled B). This should hold for the other colours as well.
  • Figs. 4 to 7 show various pixel layouts.
  • the sub-pixel colours for at least one pixel are identified with letter labels ("R", "G", "B” etc.).
  • the pixels are in repeating patterns. Where whole columns of pixels have the same colour, these are identified from above the columns. The colours of only enough pixels have been shown for the repeating pattern to be identified.
  • Fig. 4 shows a conventional pixel layout of a 2x2 matrix of RGB pixels. Each pixel has three sub-pixels, hence the subscript "3" in RGB 3 (the same notation is used for all pixel layouts).
  • Fig. 4 shows an RGBW 8 pixel arrangement having 4 primary colours and 8 sub-pixels per pixel.
  • RGB Red, Green, Blue
  • W white sub-pixels are provided. Comparing the layouts (occupying the same surface area), the perceived resolution of both layouts is similar whereas the RGBW layout results in a higher brightness (at least for LC panels): note that green and white are most important for generating a bright image (the human eye is more sensitive to green and white than it is to red and blue).
  • Multi- primary pixel layouts Pixel layouts using more than 3 primary colours will be termed "multi- primary" pixel layouts.
  • multi-primary layouts Several such multi-primary layouts have reached the market and are expected to become mainstream.
  • Fig. 5 shows several alternative RGB pixel layouts.
  • the left image is the conventional RGB 3 -sub-pixel layout.
  • the RGB 6 layout in the middle essentially spatially inverts two pairs of RGB pixels.
  • the RGB 8 layout on the right has made it to the market for 2D displays by Samsung.
  • the green sub-pixels are half as wide as the R and B sub-pixels.
  • the green sub-pixels are in columns, whereas the R and B sub-pixels alternate along the column direction.
  • Fig. 6 shows three RGBW pixel layouts
  • RGBW pixels with 4, 6 and 8 sub-pixels are shown.
  • the different proportions of different primary colours (and white) in the different pixel layouts give different brightness characteristics as well as different output colour gamut.
  • the white sub-pixels may be replaced by yellow sub-pixels, and this layout results in a larger colour gamut.
  • the invention provides an alternative approach to the problem of requiring a multiplicity of slanted lenticular designs, by providing a standardised non-slanted lenticular design and by adjusting the layout of the sub-pixels in a slanted manner to realise the benefits described above.
  • a new pixel structure can be matched to an (existing) slanted lenticular layout by providing both the lenticular and the sub-pixel structure with a slanted layout, whereby the effective slant angle is defined as the difference between the slant angle of the lenticular and the sub pixel structure.
  • the invention is based on the recognition that the sub-pixels do not necessarily have to be arranged on a rectangular grid.
  • the unit cell of such a grid can also be trapezoid- shaped.
  • Fig. 8 shows examples of a sheared pixel layout, namely one in which the rows or columns (the lines passing through the area centres of the pixel elements) are not orthogonal.
  • Fig. 8 shows RGB 3 and RGBW 8 pixel layouts (the sub-pixel colours are as identified in Figs. 4 and 6 respectively).
  • a sheared row structure is shown on the left and a sheared column structure is shown on the right.
  • the dotted line 80 represents the direction of the sub-pixel columns, i.e. the line passing through the area centres (centroids) of the column of sub-pixels.
  • the sub-pixels themselves do not necessarily need to have the rectangular shape shown in Fig. 8, and they can have a trapezoidal shape.
  • This slanted layout of pixels is possible in any matrix-based display (such as an LCD, Plasma display, OLED).
  • the invention is however particularly suitable for an active matrix OLED display, and more specifically for a top emitting OLED display, as in this type of display it is possible to laterally displace the emission area of the sub-pixel from its associated drive electronics. Why this is important is explained below.
  • OLED organic light emitting diode
  • the most logical approach would be to connect all pixels of the slanted columns to a data driver IC and all horizontal rows to a select driver IC.
  • this will result in a portion on the top right hand side of the display where the data driver IC's connect to progressively shorter columns, which may cause some image uniformity problems.
  • the data driver IC's connect to progressively shorter columns, which may cause some image uniformity problems.
  • it will be necessary to connect these columns from the other side (bottom) of the display which is particularly unsuitable.
  • the stepped arrangement of sub-pixels (as shown in Fig. 8) is interfaced with the traditional row and column connections to the driver ICs. To enable this, it is necessary to either:
  • row and/or column lines which meander along the stepped sub pixels and periodically step back as the sub-pixels shift position by either a row or a column spacing, or maintain the traditional straight row and/or column lines but to arrange the sub-pixels such that the sub-pixel emission areas are laterally displaced from the sub-pixel drive electronics.
  • Fig. 9 illustrates a meandering column conductor 90. Every third sub-pixel along the column direction, the column conductor 90 becomes associated with a sub-pixel from an adjacent column of pixels.
  • the column line is associated with a group of columns of sub-pixels, with a number (3 in this example) of sub-pixels of each column in the group associated with the column conductor.
  • the number (3 in this example) is of course a function of the slant of the sub-pixel columns.
  • the meandering column conductor has a stepped sawtooth shape. This sawtooth shape steps around the pixel elements but follows the direction of the column until the next sawtooth. Instead of a sawtooth shape, a chevron arrangement could be considered which first steps to the right from the vertical column direction and then symmetrically steps back to the column direction and then repeat this chevron structure.
  • the sub-pixel emission area is laterally displaced from the sub-pixel drive electronics.
  • the columns conductors 100 and in particular the position at which they connect using spurs to the sub-pixels, are shown are vertically displaced for visualisation reasons. In practice, all columns may be positioned at identical vertical positions. The positions of the spurs may need to be offset due to the space required for vias to connect the underlying electronics to the top layer conductors, and in some cases to avoid longer spurs short circuiting.
  • the main column conductor 100 is vertical, and horizontal spurs extend from the main conductor 100 to the sub-pixels.
  • the column conductor 100 becomes associated with a sub-pixel from an adjacent column of pixels.
  • the column line is associated with a group of columns of sub-pixels, with a number (3 in this example) of sub-pixels of each column in the group associated with the column conductor.
  • the number (3 in this example) is of course a function of the slant of the sub-pixel columns.
  • the spurs only need to extend to a maximum of one column width.
  • Fig. 10 also shows the arrangement of the electronics (for one pixel) in cross section.
  • the driver electronics 102 is connected to the OLED sub-pixel 103 by a wire 104.
  • Short circuits are avoided as the horizontal connecting wire 104 is at a higher level than the columns and other electronics.
  • the electronics is shown spaced from the pixel emission area. This means the separation distance between the centroid of the pixel emission area and the location (e.g. the centroid) of the drive electronics for the pixel is not equal for all pixels.
  • This separation distance corresponds to the length of the spur.
  • the drive electronics and the row and column conductors can be formed in a regular orthogonal grid, and the slanted columns (or rows) of pixel emission areas connect to the associated drive electronics by the spurs.
  • the electronics of the pixel can be located at the pixel emission area.
  • the separation distance between the location (e.g. the centroid) of the drive electronics for a pixel and the associated crossing point of the rows and columns is not equal for all pixels.
  • Fig. 11(a) shows a ingle pixel consisting of 4 sub-pixels
  • Fig. 11(b) shows a 3x3 array of such pixels
