The purpose of high-quality display cabinet is to make the audience receive the information most effectively in the limited time and space. Therefore, counter production is around how to effectively improve the efficiency and quality of display activities. In addition to the design of the display environment itself, the design of the display form of the display object is also an important content of a good display case production. Therefore, in addition to the study of the basic principles of general space design, the study of the visual physiological and psychological process of people when viewing display objects is the basic premise of counter making. 
The collection of high-quality exhibits will form a variety of visual factors, which will affect the vision in different degrees. There are certain commonalities in the way human beings observe things, and the study of these commonalities is the basic starting point for us to study the law of vision.
Great progress has been made in the research of visual psychology and artistic psychology in modern times, and the results of these aspects have been widely used in the design of modern display. Based on the commonality of visual behavior, many principles of plane composition, three-dimensional composition and color composition are introduced in the production of good display counters, and a relatively complete design principle and law is formed in the practice of counter production. 
The use of lines, curves, circles, triangles and rectangles is the most basic visual element of design. Straight line is the most common phenomenon in the vision, but also one of the most widely used visual elements in the production of good counters. The straight line used properly will have clear visual effects. Properly applied curves in the display can enrich the overall effect, create a change effect full of rhythm and rhythm, and change the cold and stern atmosphere caused by simple straight lines. Geometrically speaking, a circle is a shape surrounded by a continuous curve whose points are equidistant from the center of the shape. A circle is a very useful shape for counter making. It can be either a solid disc or a hollow ring. The original form should be used so that all parts of the whole can be effectively in harmony. The use of triangle or rhombic shape can produce richer visual imagination and contrast effect in the counter production; In the composition, a group of triangles in different positions is usually arranged as an asymmetric triangle group to produce rich and meaningful changes. The rectangle in the display is actually two forms, namely rectangle and square. The organic combination of rectangles and cubes with different areas and volumes can result in countless variations. This is also one of the most common ways to show reality. This can make the high-quality display cabinet more efficient presentation of products
