Display modules are available in a number of configurations, including LED, organic LED (OLED), quantum dot LED (QLED), and the ever-popular liquid crystal display ( https://www.szmaclight.com/Round-tft-lcd-display-module.html round lcd display). We#39;ve come a long way since the introduction of the 7-segment display, and new product designers now have a plethora of options to choose from when adding a display to their system. Here#39;s everything you need to know about OLED display modules for your next product.LED vs. OLED Display Modules: Which is Better?When compared to LED displays, OLEDs provide comparable resolution, dynamic range, and color depth; however, OLEDs provide higher contrast without the need for backlighting with an array of white LEDs. Because there is no need for backlighting in an OLED display, they consume less power than an https://www.szmaclight.com/Round-tft-lcd-display-module.html round lcd display. This allows the brightness of an OLED display to be tuned to produce the desired contrast. Some LED or OLED displays can also be used to provide touchscreen functionality for human machine interfaces, either as a capacitive or a resistive touch screenIf you#39;re looking for an OLED display module for an Internet of Things device, an infotainment product, or another system that requires human machine interface (HMI), here are some things to keep in mind:Consumption of electrical powerAn Internet of Things (IoT) or mobile device may operate on battery power, and you should consider the power consumption and determine how long the device can operate between recharges.Touchscreen capabilities are included. As previously stated, your https://www.szmaclight.com/new/OLED-display-technology.html small oled display module may require touch screen capabilities in order to allow for user interaction. The use of a touchscreen OLED display module eliminates the need for a keypad.Bit depth is the number of bits in a given string. The bit depth indicates the number of different color levels that the module can display for each color channel. Consider the number of different color shades that the device is capable of displaying. As an illustration, an 8-bit RGB display has the capability of producing (28)3 = 16,777,216 different colors.Resolve. The number of pixels in the display determines the resolution (i. e., the fineness of the image on the screen). More pixels in each direction generally equates to higher resolution and finer images. It is important to remember that there is a tradeoff between size and resolution; if a large and small display both have the same number of pixels, the smaller display will produce a finer image. This is why pixels per inch (PPI) or pixel pitch is a better indicator of image quality than simply counting the number of pixels.Matrix with an active versus a passive component. An array of perpendicular cathode and anode electrodes is used to provide addressing and illumination in a passive matrix OLED display module. In contrast, each pixel in an active matrix OLED display module is controlled by a thin-film transistor (TFT) that turns it on or off. Because the TFTs in an active matrix display consume less power, they are a better choice for larger displays.The display#39;s size. This is typically measured diagonally across the display area.
