Matters needing attention in the design of thin film panel

The design of membrane panel should pay attention to the problems, because the membrane switch structure is simple, easy to install and connect, novel shape, and with small volume, light weight, dustproof, waterproof, explosion-proof, anti-harmful gas, long service life and so on a series of characteristics, at present in the application of electronic machinery aroused great interest, and gradually made progress. Especially for multi-functional, intensive, intelligent electronic products, membrane switch has become the first choice of product design. In our country, membrane switch used to be very common, but there are still some gaps in the design. The following and the United States membrane switch design considerations have 5 points: Membrane switch panel design needs to pay attention to what? Membrane switch is a control system which integrates function keys, indicator elements and instrument panel. Its panels are the reflective surfaces of the membrane. The external component of the switch feature has dual functions of control function and appearance decoration.

, Color Film switch panel using surface polycarbonate (PC) , through the screen leakage printing method, the picture and text printed on the back of the film. It has the ability to arbitrarily select the desired color, which is difficult to compare to the appearance of traditional metal plates. Therefore, in the panel design, we can choose the color according to the product characteristics and application, embody the function of color, embody the advanced, scientific design concept. The application of color, although in the manufacturing process can be generally completed, but in the case of application theory, handle with care, maximize the role of color. For example, text and patterns should have greater contrast with the blocks of color they set off, and parts of key functional groups with corresponding positional relationships and interdependencies should be printed in the same color on the same page, to prevent the tendency to overprint; functional tools should be elegant and dignified; appliances can be a more beautiful decorative environment. The colors should be three or four colors. Too many colors, not only make people dazzled, but also increase the difficulty and cost of manufacturing.Text is the intermediary function of the operation, pointing directly to the operator’s function, or the performance of the instrument. When using discrete elements, panels typically use text tags near discrete elements. Membrane switch panels usually have no external components and are blocks of color that mimic a keyboard or component. To this end, text can be marked directly on the keyboard on the functional color block, making it more convenient and intuitive. In addition to the specific role of the above-mentioned text, to a certain extent, the appearance of the product, it should pay attention to the standardization of text. In addition, the choice of text form should also be integrated into the screen printing process characteristics. Therefore, the common style, such as song style, due to its weak brush strokes, thin handwriting difficult to show, color block strength does not match, Song Style and regular script, primitive simplicity, lack of creativity, fashion design style is difficult to reconcile. We recommend the use of phototypesetting text, and the use of black and thin lines of the circular body. Font stroke horizontal, vertical, width equal, font neat, easy to identify, the overall design adaptability, good reproducibility.“Graphic Design”refers to a group of specific graphic symbols, in addition to the statutory local symbols, but also according to certain operating characteristics, carefully designed to replace writing, in recent years, graphic design has been gradually applied to the design of the appearance of products, as a means of illustration. Because of the unique condition of the membrane switch panel, it can give full play to the effect of shape design, thus making the appearance more modern. Graphic design with attributes images implicit, concise, strong performance, enhance memory, can play a text notes difficult to achieve the effect. To this end in the design should also meet these standards, the pattern is not far-fetched, make people puzzled, it will affect the use of the instrument. At the beginning of the use of shape design, should be supplemented with functional text, so that people accept, develop habits, and then used alone.

The keypad shape of the keypad membrane switch is not limited by the available element shape as a discrete switch element. It can be round or rectangular, depending on the overall design. This has greater strain and sensitivity than discrete components. Generally appropriate to use rectangular, so with the appearance of the whole machine more harmonious. Although the size of the keys have not yet unified specifications, but should be suitable for use, symmetry, aesthetic standards. Especially for the key group with intensive operation function, we should pay attention to whether its size and distance accord with the Operation Habit and ergonomics relation. From the General Relationship Between Ergonomics and die manufacturing, this paper discusses the relationship between Ergonomics and die manufacturing. For transparent windows, because the membrane switch panel is made of transparent polycarbonate (PC) by special surface treatment data, so in the display part of the instrument can be integrated with the panel, there is no need to dig holes to open the window. That’s something a metal plate can’t do. There are two types of transparent window holes: a parameter that represents a display element, called a display window, and a light-emitting diode that represents an element, called a display window. Each transparent window should be designed to be transparent and colored so as to obscure the elements at the bottom, lifelike panel atmosphere, and distinguish the action functions. Choose a suitable transparent color, you can also light the digital display components filter color enhancement, so that the digital display more clearly.
