Abstract
A display method for a low analytical dot matrix display of high color relativity is carried out by driving a dot matrix display with less picture elements by an image information matrix with more picture elements. An image information process method realizes the aim of high color relativity the lowest color image distortion and reducing picture degree of analytics so as to select the gray-level drive IC with smaller channels to replace the present high value color drive IC to reduce the cost.
Description
Technical field
The invention relates to the display packing of the high low-res dot-matrix display of a kind of color correlation, be meant especially a kind of by the image data processing method, with reach color correlation height, the chromatic image distortion factor is minimum and the display packing of the low-res dot-matrix display of the purpose that reduces the picture resolution.
Background technology
The display packing of known LCD, be computing or direct sample by complexity, with the process digital average computing of image document matrix or through after filter (Filter) processing, be stored in the matrix of another corresponding LCD picture element, utilize this treated matrix again, drive the liquid crystal display screen.But above-mentioned display method has following shortcoming:
(1) said method need be handled by complicated calculations, then need use complicated calculating software/hardware, could do this computing, therefore needs to drop into more resource and cost;
(2) if said method by direct calculation process, they must be in several pixel points, just can get the color message of a pixel points, therefore can lose too many pattern message, cause on the LCD linking drop between the diagram plots vegetarian refreshments too big, can produce the distortion of figure, the discontinuous or discontinuous figures of color of lines makes resolution too low.
Supervise in this, No. 377429 patent case (call in the following text and quote case as proof) announced in the display packing such as the Taiwan of dot-matrix display commonly used, and its main composition is characterized as: image data matrix that can picture element is more drives the less dot-matrix display of picture element.Arrange sampling mode by image data, have the purpose of calculating simply and reaching the reduction resolution; And the major defect on its formation is: the image sampling mode is too simple, will cause the image distortion significant disadvantages.
This shows that above-mentioned common method still has many defectives, and need be improved.
