A projector LCD board is a special type of projection. The imaging component of a projector LCD board is the LCD board, and the projector LCD board usually uses external light for projection. The signal transmission method of the projector LCD board is mainly through digital to analog data conversion. The advantage of a projector LCD board is that it is very light in weight and very portable. The following is a small introduction to what a projector LCD board is and the size of a projector LCD board.
lcd display manufacturers, specializing in the development and production of LCD monitors. High-quality products, low power consumption, fast delivery, and reasonable price.
The imaging device of the projector LCD board is a liquid crystal board, which is also a passive projection method. The use of external light source metal halide lamp or UHP (cold light source), if the design of three LCD board is strong light through the beamsplitter to form RGB three beams of light, respectively, through the RGB three color LCD board transmission; signal source after analog-to-digital conversion, modulation added to the LCD board, control the LCD unit open, close, so as to control the light path interruption, and then by the mirror combined light, magnified by the optical lens, displayed on the large screen. The common LCD projector on the market today is the more popular single-chip design (LCD single board, light does not need to be separated), this projector is small in size, light in weight, extremely convenient to operate and carry, and relatively low in price. However, its light source life is short, its color is not very uniform, and its resolution is low, with a maximum resolution of 1024 x 768, and it is mostly used for temporary presentations or small meetings. Although these projectors also achieve digital modulation of the signal, the physical characteristics of the liquid crystal itself determine its slow response time and performance declines over time.
Projector LCD board burn causes and solutions: projector LCD board burn is mostly caused by high temperature or unstable power supply, where the projector power supply board is prone to capacitance problems after a few years of use, when the LCD screen will appear snow, noise, etc. In addition, the projector should be regularly maintained, clean up the internal dust, check whether the fan and other components are faulty, to prevent fan failure when the heat can not be effectively distributed, accelerating the damage to the LCD board.
Projector LCD board size: 0.9-inch and 0.7-inch panel production is currently the largest, the proportion of more than 70%, 1.3-inch products proportion of about 15%, 0.5-inch, 0.79-inch, 0.99-inch and 1.0-inch panels also began to be used for projector products. In the number of LCD panels, due to the single-chip structure in the performance and color defects, has now been largely eliminated. The current mainstream is the 3-chip LCD projector, which has represented the most mature level of projector product development for a long time due to its excellent performance and color. With the same brightness and resolution, the smaller the projector, the higher the price.
