摘要： A bitmap of a shape, such as a font, can be subpixel optimized by producing for each of a display's subpixels a coverage value representing the percent of its area covered by the shape being represented and by distributing, to prevent color imbalance, an amount of a given subpixel's coverage value to nearby subpixels of different colors as a function of the percent of the given subpixel's coverage value that causes color imbalance. Web pages can be displayed with scaled-down and subpixel optimized images. A given layout of a Web page can be displayed at each of at least two different selected scale factors, with the font bitmaps used to represent characters in the display at each scale factor having their shape and pixel alignment selected to improve readability for the particular pixel size at which they are displayed at each such scale factor.

摘要： A method for creating anti-aliased characters on a computer output device includes the steps of generating a call from a client process for a character to be rendered, selecting a best alignment grid from a set of alignment grids associated with the device grid, rendering the character at a high resolution, and aligning stems of the character with an alignment grid corresponding to the resolution of an output device. The step of aligning the high resolution rendered stems to the alignment grid provides for an anti-aliased output with balanced stems.

摘要： Character data to be displayed is obtained. The obtained character data is boldfaced by increasing a character line width of the obtained character data in a first direction by an amount corresponding to at least a width of a light-emitting element. A boldfaced character is displayed on a display screen in accordance with data derived from the boldfaced character data. In boldfacing the character data, a character line width-increasing pattern is selected in accordance with a degree to which the luminous intensity of the light-emitting elements contributes. In particular, the step of increasing the character line width in order to boldface the character data avoids a pattern in which a B-light (blue) emitting element is located at a next-to-endmost inner position of the increased character line width. A light-emitting pattern is selected in order to eliminate an isolated sub-pixel spot, which otherwise would objectionably be visible in the boldfaced character.
摘要翻译：获得要显示的字符数据。通过将获得的字符数据的第一方向的字符行宽度增加至少与发光元件的宽度相对应的量来将获得的字符数据粗体化。根据从粗体字符数据导出的数据，在显示屏幕上显示粗体字符。在以粗体显示字符数据的情况下，根据发光元件的发光强度的贡献度选择字符线宽度增加图案。特别地，增加字符行宽度以粗体字符数据的步骤避免了B型（蓝色）发射元件位于增加的字符行宽度的下一个最内侧位置的图案。选择发光图案以消除孤立的子像素点，否则将在粗体字符中令人反感地看到。

摘要： The invention is related to a new kind of dithering method for plasma display panels. In a former Europena Patent Application a dithering method for the plasma display technology has been presented that utilizes a 3-dimensional dither pattern for the repeated use in a video sequence. A first dimension corresponds to a number of video frames, a second dimension corresponds to a number of video lines, and a third dimension corresponds to a number of cells or pixels in a video line. It has been found that this dither pattern has for some video levels the drawback of a generating a noticeable pattern in homogenous surfaces on the screen that reduces the picture quality. In order to overcome this drawback the invention proposes a new degree of freedom for the dither pattern. Different dither patterns are provided for different entries in a number of least significant bits of the data word representing the input video level. The invention makes it possible to suppress the disturbing patterns occurring on the plasma screen when using the conventional dither patterns.
摘要翻译：本发明涉及一种用于等离子体显示面板的新型抖动方法。在前欧洲专利申请中，已经提出了一种用于等离子体显示技术的抖动方法，其利用三维抖动图案在视频序列中重复使用。第一尺寸对应于视频帧的数量，第二维度对应于视频行的数量，第三维度对应于视频行中的单元或像素的数量。已经发现，这种抖动图案对于一些视频级别而言，在屏幕上的均匀表面中产生显着图案的缺点在于降低了图像质量。为了克服这个缺陷，本发明提出了一种抖动图案的新的自由度。为表示输入视频电平的数据字的多个最低有效位中的不同条目提供不同的抖动模式。本发明可以抑制当使用常规抖动图案时在等离子体屏幕上发生的干扰模式。

摘要： A plasma display device (10) is provided with circuitry (50) which modifies at least the R and B color component signals so as to compensate for the displacement of the display elements or sub-pixels for each color component relative to each other in the array. Surprisingly, this increases the ratio of wanted signal to alias spectrum. The modification is effected by an interpolator comprising transversal filters (31R, 31B). The circuitry can be combined with down-converters (52) when a high definition source is used. In this case a transversal filter (31G) is also included for the G color component signal.

摘要： A method of displaying an image, wherein a first density of image pixels, each comprising a sub-pixel is displayed on a display having a second density of display pixels. Each display pixel has at least two spatially offset display sub-pixels. The display sub-pixels are able to display a first color and a second color, respectively. According to the invention, the image is resized to an intermediate image having a third density of intermediate image pixels, each comprising an intermediate image sub-pixel, and the display sub-pixels are displayed with a respective intensity which is determined from the corresponding intermediate image sub-pixels. This reduces the image artifacts when the display screen is used with different image standards.

摘要： The present invention provides a pixel driving module of a liquid crystal display, wherein a display panel thereof is formed by uniformly and alternately arranging a plurality of sub-pixels selected from the three primary colors of red, blue, and green in mosaic, turtleback, or checker form. The pixel driving module connects each transversal row of sub-pixels together with a parallel signal scan line. Each of the data transmission lines forms an indent strike to longitudinally connect in order a sub-pixel in every two adjacent transversal rows together. The present invention has the advantages of shrinking the pitch of sub-pixels, increasing the area and window ratio of display pixels, enhancing the resolution of the display, and reducing the impedance of the driving module.

摘要： When a sub-pixel of B having a small contribution to luminance emits light in isolation, a sub-pixel of R is caused to emit light or sub-pixels of B and R are caused to emit light. As a result, a sub-pixel of R having, a larger contribution to luminance than the sub-pixel of B, is caused to emit light. When an adjacent set of sub-pixels B and R having a small contribution to luminance emits light in isolation, a set of sub-pixels R and G is caused to emit light. As a result, a set of sub-pixels R and G having a higher degree of contribution to luminance than the set of sub-pixels B and R is caused to emit light. Therefore, contrast degradation from any allocation of light-emitting patterns to sub-pixels having poor luminance is eliminated and a high quality display is achieved.
摘要翻译：当具有对亮度贡献小的B的子像素分离发光时，使R的子像素发光，或使B和R的子像素发光。结果，导致对亮度比对于B的子像素更大的贡献的R的子像素发光。当对亮度贡献小的相邻的一组子像素B和R分离发光时，使一组子像素R和G发光。结果，使得对于亮度比对子像素B和R的集合具有更高的贡献度的一组子像素R和G被发光。因此，消除了从发光图案的任何分配到亮度不良的子像素的对比度劣化，并且实现了高质量的显示。

摘要： Display apparatus, and methods for displaying images, e.g., text, on gray scale and color monitors where each pixel includes multiple pixel sub-components are described. Filtering and/or displaced sampling is used to generate pixel sub-component luminous intensity values. As a result of treating pixel sub-components as distinct light emitters corresponding to different image portions, resolution is enhanced but color errors may be introduced into the image being displayed. Various techniques for detecting noticeable and/or distracting color errors are described. In addition, various techniques for correcting, compensating for, or reducing color errors are described. In one particular embodiment, red, green and blue pixel sub-component luminous intensity values are examined and compared to a range of luminous intensity values which is determined as a function of utilized foreground and background pixel colors. Pixel sub-component luminous intensity values which are determined to be outside the range of acceptable values are adjusted to fall within the range of acceptable values. In one particular embodiment, individual pixel sub-component luminous intensity values outside the range of acceptable values are clamped to the nearer of the foreground or background pixel sub-component luminous intensity value of the correspondingly colored pixel sub-component. In another embodiment sequential red and blue filters are used to reduce or compensate for color distortions.

摘要： Techniques for improving the resolution of images (either analog images, analytic images, or images having a higher resolution than that of a display device) to be rendered on patterned displays. In one aspect of the present invention, an overscaling or oversampling process may accept analytic character information, such as contours for example, and a scale factor or grid and overscale or oversample the analytic character information to produce an overscaled or oversampled image. The overscaled or oversampled image generated has a higher resolution than the display upon which the character is to be rendered. Displaced samples of the overscaled or oversampled image are then combined (or filtered). An analytic image, such as a line drawing for example, may be applied to the oversampling/overscaling process as was the case with the character analytic image. However, since the analytic image may have different units than that of the character analytic image, the scale factor applied may be different. Since an ultra resolution image is already “digitized”, that is, not merely mathematically expressed contours or lines between points, it may be applied directly to a process for combining displaced samples of the ultra-resolution image to generate another ultra-resolution image (or an image with sub-pixel information). The functionality of the overscaling/oversampling process and the processes for combining displaced samples may be combined into a single step analytic to digital sub-pixel resolution conversion process.
