Problems solved by technology

[0004] However, this approach has its disadvantages. When the distance between the user and the display screen is very close, or when the area to be displayed is very small, these halftone patterns can be clearly distinguished from black and white interlaced patterns or Lines; in this way, the visual effect to be achieved above cannot be achieved
For the display screen of a portable device, such as the LCD screen of a mobile phone, the visual effect achieved by the above-mentioned method of increasing the number of gray scales is very limited.
Therefore, the above-mentioned method of increasing the number of gray scales is only suitable for displaying the same color on a large display screen, and is not suitable for a small display screen.

example 1

[0032] In the first stage of Example 1, by sending data to the LCD (for example, the application program issues a drawing command, and then conveys it to the LCD through the operating system), to stimulate the pixels (or at least a certain pixel) in a certain area of ​​​​the LCD to display the color X and wait It is approximately equal to this response time T=300ms. At this time, the specified pixels on the screen display the color X, which is the color represented by 11000000. Please refer to figure 2 , the arrow representing the arrow 230 of the first stage corresponds to 11000000 of the axis 200, indicating that the colors displayed by these pixels have changed to color X.

[0033] After that, enter the second stage, by sending data to the LCD, to excite these pixels to display the color Z and wait substantially equal to the display completion time T XY Time T summed with a delay time S XY +S. As shown by arrow 240 representing the second stage, the color of those pixel...

example 2

[0037] In the first stage of Example 2, by sending data to the LCD, the pixels (or at least a certain pixel) in a certain area of ​​the LCD are excited to display the color X and the waiting time is approximately equal to the response time T=300ms. At this time, the designated pixels on the screen display the color X, which is the color represented by 11100000. Afterwards, by sending data to the LCD, to activate these pixels to display the color Z and wait substantially equal to the display completion time T XY time T with a sum of delay time S XY +S. At this time, the colors of these pixels designated to display color Y continue to change, from color X to color Z, that is, the opposite process of the relative process of example 1 is changed, from 11100000 to the color represented by 11000000. Let S=5ms be a period sufficiently less than T=300ms, then T XY +S=95ms. After a time of 95ms, the colors displayed by these pixels have approached the color Y level. At this time, ...

Abstract

The invention is a display method for adding colors, making flat display screen use first and second displayable colors to display a desired color undisplayable based on the hardware design itself, where this color is between the first and second displayable colors. A least one pixel of the screen is excited to display the first color and waits for a response time of the screen. Successively, this pixel is excited to display the second color and waits for a display achieving time which is based on the numerical values of the first color and the desired color and determined according to the difference of the numerical values of the first and second colors as well as the response time. Finally, just exciting this pixel to make the displayed color by it change slightly and alternatively nearby the order of the desired color can achieve the purpose of displaying the desired color.

Description

technical field [0001] The present invention relates to a color increasing method, and in particular to a color increasing display method for a flat display screen. Background technique [0002] The display screens of portable devices currently on the market, such as mobile phones, personal digital assistants (Digital Personal Assistant, PDA), electronic dictionaries, etc., generally adopt flat display screens such as liquid crystal display screens, which are divided into black and white, gray scale, color, etc. There are different grades of color such as 256 colors, 4096 colors and 65536 colors. Each level of LCD screen is limited by hardware, and the number of colors that can be displayed by each point (pixel) on the screen can only be within a predetermined range. And this limitation of the number of colors is reflected in the amount of data required for one pixel; for example, each pixel of a black and white screen requires only 1 bit, and each pixel of a grayscale scre...
