Description of the Invention (1) [Field of the Invention] The present invention relates to a method for screen refresh, which is applied to a screen for displaying electronic data, and in particular, a method for screen refresh which improves the refresh speed and can satisfy the requirements of multiple logical layers. . [Background of the Invention] Screen refresh (ref re sh) refers to updating and refreshing the content of the screen. Generally speaking, it generally occurs in two situations, one is the refresh of the screen setting timing, and the other is when the screen is inside. Changes, or refreshes that must occur when running programs. The conventional screen refreshing method mostly adopts the "painter" algorithm, that is, regardless of whether the screen content changes, all content needs to be redrawn to refresh all the screen content, so the speed is quite slow. At the same time, some other refreshing algorithms only provide refreshing at two logic levels, which cannot meet the screen refreshing requirements of multi-layer logic architectures, which may easily cause errors after screen refreshing. [Objective and Summary of the Invention] The present invention is to provide a method for screen refresh in order to solve the above problems, which can increase the speed of screen refresh and can be applied to a multi-logic architecture. According to the screen refreshing method disclosed in the present invention, it is first determined that a change in an object appears on the screen, that is, all entities on the screen are regarded as an object, and the change includes enlargement, reduction, displacement, distortion, or text content Wait for changes, then convert them into a variable according to the changes, and merge the variables of adjacent objects with each other to reduce the number of refresh areas, and the combined

After all the objects are calculated and stored, take them out-and add ^ Update. In addition, you can also design and combine the changes of objects in different logic layers to improve the refresh speed. In order to understand the objectives, structural features, and functions of the invention, the detailed description of the illustrations is as follows: [Detailed description of the embodiment] Figure root = Screen refresh method disclosed by the invention, please refer to "Parameters" Second: Γ — the content of the screen, first of all, when the objects in the screen are out of the object, they are in the screen; (step 101), the so-called when the object has changed, including: put a picture?-Law as-an object , Image changes, etc. At the same time, the largest area occupied by the flavor reduction, distortion, and object connection is Meijin. In the next paragraph, select the variable of the object before and after the change and record it in / for the supply. After processing, Relevant data is converted into Yili 1 ° green in an alternative linked list. Then handle the displacement of the object (step u figure), when an object!

And step 2 2) "and join the alternative linked list after conversion, Y For the logical layer, please Refer to "Figure 6", each object has a so-called "Z order": 3 thoughts represent the sequence relationship on the screen. Each "z order" value can be treated as a logical layer. The objects in the figure 6 6 6 6 6 64 The value relationship is that the object 64 is at the forefront and the object U is at the bottom. 'Simply said, the object 64 covers the object 63, the object 63 covers the object 6 2', and the object 6 2 covers the object 61. When processing, only the object is pulled out. The area involved in the change of the object is processed, and an example is given below for illustration. As shown in "Figure 7A", the "z-order" of the three objects is 73, 72, and 71 according to size. When the object 72 slides to the right (see the first few pictures), the part to be updated is object 7. The area of 2, 7 4 but the two are treated differently.
