  For Photoshop beginners, learning Photoshop is equivalent to learning Photoshop basic tools. Skills and methods for using commonly used tools need to be mastered. Regarding the learning of Photoshop tools, JRPanel recommends that you combine the learning of examples to quickly grasp it, and deepen the memory and learning effect of learning. Let me share with you the basic examples of Photoshop graphic tutorials, and teach you 5 quick selection tool skills commonly used in Photoshop. 1. Magic Wand Tool This is the easiest way to create a selection, but it is only effective when the background color is a solid color.   Therefore, when the background of the object to be selected is a blank background, you can use the magic wand tool, such as a product shot.   When creating a selection, first of all, to ensure that the picture is in a layer, just right-click the background layer and choose ‘Layer from Background’. Then, select the magic wand tool and click on the background. In this way,

  The intelligent digital measuring and controlling instrument is a kind of intelligent instrument, which adopts single-chip technology, which integrates display, measurement, calculation, control and remote transmission. It is widely used in industrial control, electrical measurement control and other fields.   The picture shows the appearance of the membrane switch panel of the intelligent digital measurement and control instrument.   There are four colors: light gray, dark gray, blue, and white. Light gray is used for decoration, dark gray is used as the main background, blue is used as the button area, and white is used as the color of text and instructions. So there are 4 colors in total.In the middle is a rectangular transparent window, and there is a small rectangular transparent window at the bottom right of the rectangular transparent window. Below the rectangular transparent window is a line of white text, which is the English of Smart Digital Display Control Instrument. Cont

  Membrane switch is a new type of high-tech switch with decorative function and marking function; besides the switch and manipulation function of switch element, membrane switch also has switch connection and lead wire (that is, Switch circuit) function, with transparent window for reading display and transparent window for indicator light. Because the membrane switch has the characteristics of simple structure, beautiful appearance, excellent environmental resistance, long service life, light, thin, short, small, etc., it conforms to the development direction of modern electronic instruments with high integration and high intelligence, therefore favored by high technology products.   The membrane switch uses screen printing as the main process method. The main production process is as follows:   Engineering drawing--color separation/ film production--material cutting--color matching/ink adjustment--silk print screen making--screen printing--drying-positioning holes/metal shrapnel, LE

  Since the birth of the membrane switch, it has experienced several technological innovations. JRPanel would like to talk about the development trend of membrane switch technology today . Multifunctional integrated membrane switch  The traditional membrane switch only has the function of switching on and off, and has a single function. According to the needs of instruments and meters, electronic components (including RC components, inductance components, light-emitting devices, sound-emitting devices, etc.) have been installed into membrane switches, and new light storage and fluorescent inks have been applied. The membrane switch integrates multiple functions such as switches, decorations, regular panel notes, luminous displays, and sound prompts, and realizes part of the circuit board functions.   Screen printing isolation layer   The structure of the membrane switch requires that the two circuits must have an isolation layer, which plays the role of separating the circuit, controll

  Today JRPanel would like to discuss with you about the necessity and importance of membrane switches prototype.   Prototypes are an important basis for the quality control of JRPanel membrane switches and a tool for communication with customers. Its functions are mainly reflected in the following two aspects.   First, the prototype can help customers check the various information contained in the document so that they can be modified in time, such as fonts, patterns, colors, etc. Color is the most difficult to control in prototype, because different panel materials and ink thinness will cause the color of the prototype to change.   Second, the prototype can be used as a contract between the customer and the membrane switch factory. The contract prototypes should accurately provide the same color as the final membrane switch, and the contract prototypes should be printed out shortly before mass production to avoid fading and distortion of the prototypes due to long storage time.   pro

When designing a membrane switch panel, we usually need to decide whether to design a window based on whether the machine uses LED or LCD. Today we will talk about some design suggestions for this process.   What is a membrane switch window?   The membrane switch window is a transparent or semi-transparent area on the panel for the user to observe the display of the LED or LCD behind the panel.   The options of the membrane switch window are as follows:   1. Transparent window: a transparent area without any color. 2. Filter window: The area printed with translucent ink, usually red, green or yellow, in order to distinguish the color of light-emitting diodes. 3. Opaque window: The area printed with multiple background colors. Unless the indicator light on the back is illuminated, they are invisible. It is used for indicating legends and graphics. 4. Printed window: The bottom of the window is relatively rough, and the surface is printed with special ink to form a transparent area for t

  The COVID-19 corona virus epidemic has been tossing for more than half a year, and so far there is no sign of its death. The epidemic situation in many places in the world is still in a stalemate, and other places where epidemic prevention has achieved initial results are afraid to be careless, and are ready to wait for the corona virus virus that may come back in autumn and winter. Although there is no answer to when the epidemic will end, it is certain that the corona virus epidemic has completely activated the medical electronics market.   It is generally recognized that the medical electronics market is a tepid and continuous growth "slow cow". Everyone knows that after the outbreak of the corona virus epidemic, the demand for ventilators has surged-in 2019, the global market demand for ventilators is about 77,000, and in April 2020, New York, USA alone will need 33,000 ventilators. The same example is the forehead gun around us. The price soared in the first few months
