Abstract

一种至少包括两个明显不同区的显示器。一个彩色子象素区域分组以形成全色象素以及至少另一区域用于显示字符,此区的全色区中单色象素的子象素具有相同的间隔。由此至少沿一个方向导致显示器的单色区的象素分辨率大于全色区的象素分辨率。

Description

具有间隔分区的发光显示器
技术领域
一般说来，本发明涉及显示器，这种显示器至少有两个区：一个显示图像和另一个显示字符。
背景技术
全色显示器的应用经常要求在全色图像中或者全色图像附近显示字符。在通常情况下，字符的可接受的分辨率大于相伴的全色图像需要的可接受的分辨率。于是在整个显示器区减少象素至象素的距离以便提高字符的分辨率或者对字符数据采用分立的较高分辨率的显示器。这种显示器的实例是在图像下面显示字符的图象电话、在屏幕下方有存储或信息数据的电视、和在图像周围显示字符的摄像机取景器或显示器。
这些全色显示器的许多优选技术如液晶显示器(LCDs)、发光二极管(LED)显示器、以及有机发光二极管(0LED)显示器都使用附加的彩色子象素。这种显示器的制造包括使用增加成本和难度的光刻工艺，这是因为减小了子象素到子象素的间隔。于是，因为提高了整个显示器的分辨率或在分立的较高分辨率显示器上显示字符，所以提高了充分地显示字符和图像的成本。
发明内容
本发明的一个目的是在全色显示器上提供能够显示比全色区有更高分辨率的单色字符的区域。
此目的用一种显示器来实现，它包括：
A)单独可寻址的及可电场激活的子象素阵列；
B)该阵列的至少一个区，其中子象素有不同的颜色同时分组以制造形成全色显示图像的象素；以及
C)该阵列的至少另一个区，其中子象素全都是单色的由此提高此区的分辨率。
本发明的优点在于可以实现局部提高分辨率而并不降低用于产生完全显示的光刻工艺的线分辨率。制造子象素的步骤和重复图模(artwork)对显示器的全色区和单色区可以是相同的。单一的显示器比分立的帧显示器占据较少的空间，而且在单一显示器中降低了单独可寻址的象素的驱动电路数目。
附图说明
图1是具有全色和单色区剖面的显示器，这些区被放大以显示子象素颜色。
图2示出象素与子象素的间距，这些间距是针对图1全色区的放大剖面的。
图3示出象素和子象素的间距，这些间距是针对图1全色区的放大剖面的。
图4示出图1中显示器的全色部分的另一种象素阵列。以及
图5示出图1中显示器的单色部分对应的另一种象素阵列。
具体实施方案
现在参照图1，它展示根据本发明的一种显示器20，它有两个分立区，一个是全色显示区22，一个是单色字符显示区24。人们将了解，为了实施本发明，必须至少有两个分立的显示区：一个是全色显示区22，一个是单色字符显示区24。图1中包括的是：显示器20的全色区22的一部分被放大的视图，其中有不同颜色的子象素；红色R、绿色G、蓝色B，以及一种未定义的子象素区U，这些子象素分组形成全色图像显示的象素40。该未定义的子象素区U可以搁置不用或可以包括第二红色R，绿色G，或蓝色子象素。图1也示出了用于字符显示的单色区24的部分的放大视图，其中子象素S都是同样的颜色，图1所示优选的实施方案中的二个区的子象素的间隔均相同，这如图2和图3清楚所示，在图2和图3中，沿x方向的子象素到子象素的间隔28与沿y方向的子象素到子象素的的间隔32均相同。在该实施方案中，单色区的子象素S变成象素40并且根据同全色区的象素40的比较具有针对沿x方向和y方向的每一个全色象素40的两个象素40。因此，例如在字符显示区的全色分辨率，从(800×600)的象素显示提高到(1600×800)的象素显示。这在视频显示中可能是特别重要的，此时，较低的分辨率对稳定变化的图像是足够的，但较高的分辨率对慢速更新的字符则是需要的。
现在转到图4，图4示出了另一种实施方案，其中在显示器20的全色部分形成全色象素40的红色R、绿色G、和蓝色B子象素，它们沿x方向以象素间隔26和子象素间隔28以及沿y方向以相等的象素30和子象素间隔32排成一线。其次图5展示出显示器20的单色区24沿x方向相等的子象素28和象素间隔26以及沿y方向相等的子象素32和象素间隔30。在此情况下，x方向的单色区24的分辨率比全色区22的分辨率大三(3)倍。然而，沿两个区y方向象素的分辨率是相同的。
其它的实施方案也是可能的，即当比较单色区的象素间距和全色区的象素间距时，通过重排子象素的位置x和y方向的分辨率能得到不同的提高。
