Internal Structure of LCD Display

If a voltage of one degree is applied to the liquid crystal slab box of the LCD display liquid crystal screen and reaches a necessary value, the long axis of the liquid crystal slab of the LCD display liquid crystal screen will be skewed along the magnetic field position from the beginning, and when the voltage reaches about two times the threshold voltage, the liquid crystal slab between the two grids in the liquid crystal slab box of the LCD display liquid crystal screen will be displayed along the magnetic field position, except for display method will be displayed along the magnetic field position except for the display method. At that time, the performance of 90° rotation is not obvious, and the rotational effect is obtained between orthogonal polarizers so that there is no light leakage on the surface of the machine, and the optical effect is obtained between parallel polarizers so that the machine no longer obscures the LCD display.

LCD display liquid crystal plate display device imaging principle is the LCD display liquid crystal plate placed between two pieces of thermal glass, driven by the magnetic field between the two grids, the liquid crystal plate of the magnetic field effect of the aberration, so as to master the light source of the transmittance or coverage performance, the power off and on between the light and darkness and the image will be exposed, if you add a black and white filter, black and white image can then be exposed.

At present, all layout graphics and large sum layout characters, LCD display liquid crystal screen, liquid crystal plate display parts are used STN mode, STN technology in the liquid crystal plate performance is in the infantile and perfect stage. STN mode of the item construction and TN mode is basically the same, only the box of liquid crystal plate on the display of people is not along the 90° skewed display, but 180° ~ 360° skewed display.

Since we used TN type liquid crystal slabs in the display tracing, the twisted spiral moment of the liquid crystal slabs in the box is much longer than that of the visible light band. This is because when the position of the LCD display in the form of glass on one side is different from the position of the liquid crystal slab, or when orthogonal curved polarized light is injected, the position of the polarized light is twisted by 90° after passing through the entire layer of the liquid crystal slab and is ejected from the other side. Therefore, a certain liquid crystal slab box can be shielded between parallel polarizers, and its surface can be shielded between orthogonal polarizers capable of leaking light for utility and performance. The two glass substrate clothes have the alignment film, because the liquid crystal slab of the LCD display liquid crystal screen will be aligned along the groove, because the groove of the alignment film of the glass substrate deviates from the orthogonal path by 90°, because the liquid crystal slab of the LCD display liquid crystal screen changes, and the light passes through the polarized light plate along with the liquid crystal slab of the LCD display liquid crystal screen by 90 degrees when the glass substrate does not exit the magnetic field. When the glass substrate is not out of the magnetic field, the light passes through the polarized light plate and changes 90° with the liquid crystal plate of the LCD display, and the liquid crystal plate of the LCD display shows red color through the polarized light plate below.

When the glass substrate exits the magnetic field, the liquid crystal plate undergoes a matching change, and the light passes through the gap of the liquid crystal plate, keeps its original position, and is covered by the polarized light plate underneath, and the light is attracted but passes through, and the panel of the LCD display liquid crystal panel of the liquid crystal plate reveals color.
