The movement of the stars and the peach blossoms, the screen of the display has changed from convex to straight, and now it has gradually become popular. People can't help but feel that there is no subversive technology display for many years, and it really has to be "changing the sky." After solving the problems of surface technology barriers, panel yield and productivity, curved display has become a signature dish in the display market. It is not popular, but it is a household name.
The rise of curved displays naturally has its advantages. Especially in the case of large-size screen display, the image formed in the human eye in the edge area picture is optimized, and the screen curved inward makes the distance between the points of the image and the eyeball the same, so the edge quality is clearer than the flat display. And effectively increase the sense of presence and immersion.
Curved TV has attracted much attention because its display has been transformed from a traditional rigid flat design to a smooth and soft curve design. In addition, the difference between curved TV and traditional TV has attracted consumers' attention. Curved TV enables each point on the screen to reach the eye at the same distance, whether it is the center or edge of the screen. At the same time, the viewer can get the best viewing effect even from the edge of the screen, and the viewing angle is wider. You can experience the feeling of being shocked and the ultimate sense of immersion when you are not in the house. This means that the curved TV provides a more visible viewing value based on the change of the traditional flat-panel TV design.
Curved TV is by no means simply bending the flat display by changing the physical properties. The precise calculation of the curvature gives the viewer a more perfect picture quality. In the eyes of consumers, behind the display screen, which is just a piece of glass, there are hidden series of ultra-thin circuit boards and driving devices that display color and evenly distribute photoelectricity.
First, let’s take a look at the most important component of curved TV – LCD.
Principle of LCD imaging: By supplying power to a liquid crystal material that is regularly arranged in a certain direction, the alignment direction of the liquid crystal material is changed, thereby controlling the passage of light or blocking the light source to achieve final imaging.
The LCD is constructed by placing a liquid crystal cell in two parallel glass substrates, a TFT (thin film transistor) on the upper substrate glass, and red, yellow and green color filters on the lower substrate glass, and loading the backlight ( Backlight) and polarizing plate.
Whether the quality of the curved TV picture is clear or not depends mainly on whether the internal layer structure can work normally when the LCDpanel is bent. LCDpanel technology is therefore an extremely important part of curved TV.
Push Button Switches
The Push Button Switches, also known as the control button (referred to as the button), is a low-voltage electrical appliance that is manually and generally can be automatically reset. The Push Button Starter Switch is usually used to issue a start or stop command in the circuit to control the turning on and off of electrical coil currents such as electromagnetic starters, connectors, and relays.
The On Off Push Button Switches refers to a switch that pushes the transmission mechanism with a button to make the movable contact and the static contact open or close and realize circuit switching. It is a master control device with a simple structure and a wide range of applications. In the electrical automatic control circuit, used to manually send control signals to control connectors, relays, electromagnetic starters, etc.
This Pushbutton Switches is a kind of electric device that is used to switch on and off the small current circuit when the action is released. Generally used in AC and DC voltage below 440V, the current is less than 5A in the control circuit, generally do not directly manipulate the main circuit can also be used in the interconnection circuit. In actual use, in order to prevent desperation, different marks are usually made on the buttons or painted with different colors, and the colors are red, yellow, blue, white, black, green, and the like.
The Momentary Push Button Switch could be divided into metal push button switches and LED Light Switches and ordinary snap button type, mushroom head type, self-locking type, self-resetting type, rotary handle type, with indicator light type, lighted symbol type and key type, etc., with single button and double Buttons. Generally, it adopts a water-storage structure, which consists of a button cap, a return spring, a static contact, a moving contact and a casing. It is usually made into a composite type, and has a pair of normally closed contacts and normally open contacts, and some products can pass. The series connection of multiple elements increases the number of contact pairs. There is also a self-contained button that automatically holds the closed position when pressed, and can be turned on only after the power is turned off.
When the Metal Switches is not pressed, the movable contact is connected with the upper stationary contact. The pair of contacts is called a normally closed contact. At this point, the movable contact is disconnected from the following static contact. The pair of contacts is called a normally open contact: the button is pressed, the normally closed contact is open, the normally open contact is closed, and the button is released. Restore the original working state under the action of the return spring
