Description
Technical Field
The invention relates to the field of display devices, in particular to a liquid crystal box and a 2D and 3D switchable display device.
Background
Naked eye 3D is a novel stereoscopic display technology, and a viewer can enjoy a good stereoscopic display effect without wearing any auxiliary glasses or helmet and other equipment. The naked eye 3D has the characteristics of simple structure, low manufacturing cost, good performance and the like. According to different adopted gratings, naked-eye 3D display can be divided into slit grating 3D display and cylindrical lenticular grating 3D display.
The 3D display principle of the cylindrical lens is that a layer of cylindrical lens is added in front of a liquid crystal display screen, so that the image plane of the liquid crystal display screen is positioned on the focal plane of the lens, and thus, the pixel of an image below each cylindrical lens is divided into a plurality of sub-pixels, so that the lens can project each sub-pixel in different directions, and a viewer can view a stereoscopic image when the viewer is positioned at a proper viewing position.
The principle applied by Switch Cell (2D and 3D switching unit) is to use the cylindrical lens 3D display technology and the rotation of liquid crystal to display the 2D and 3D transitions. A layer of columnar lens is added between two glass substrates with transparent electrodes, then liquid crystal is filled, and the rotation of the liquid crystal is controlled through external voltage, so that the conversion between 2D and 3D is realized.
In the existing product design, a glass substrate is provided with a comprehensive ITO layer, PI liquid coating (alignment liquid coating), sealant coating, liquid crystal dropping and other Switch cell box forming actions are carried out on the ITO layer, wherein electrode layers of an upper substrate and a lower substrate are all full-face ITO layers, part of the ITO layers are located outside a sealant frame, and liquid crystal molecules are located in a closed space formed by the sealant frame and the upper electrode layer and the lower electrode layer. In a high-humidity environment, the ITO layer outside the sealant frame absorbs water vapor to form a water film containing a small amount of hydrogen ions and hydroxyl ions, and also dissolves oxygen and other gases, thereby forming an electrolyte layer on the ITO layer. When the upper and lower substrates are energized, a potential difference is generated, which causes electrochemical corrosion of ITO and extends to the display area, resulting in reliability failure.
Specifically, in the use process of the ITO, the voltage difference between the electrodes can cause electrochemical corrosion due to the influence of water, oxygen, impurities (such as chloride ions) and the like in the air. The ITO film is subjected to cathode polarization and anode polarization respectively, and the phenomenon that the ITO does not corrode when serving as an anode and obvious electrochemical corrosion phenomenon occurs when serving as a cathode is found.
And the ITO cathode corrosion has a critical voltage, ITO is not basically corroded below the critical voltage, electrochemical corrosion can occur after the voltage is exceeded, and the corrosion current density is increased along with the increase of the cathode voltage. In addition, the ITO thin film is more susceptible to electrochemical corrosion under acidic conditions, the corrosion current density increases with increasing acidity, and the corrosion of ITO increases with increasing basicity under basic conditions. The larger the ITO etching rate, the larger the square resistance of the sample after the etching reaction. According to the calculation formula of the resistance: r ═ Rs (sheet resistance) × L (length)/W (width), it can be seen that the resistance of the corresponding block also increases, and the multimeter found the non-conduction phenomenon when measuring the resistance between the abnormal region and the normal region.
And the surface of the ITO becomes uneven after cathode corrosion (the measurement result of a step profiler shows that an abnormal area is higher than a normal area by hundreds of nanometers with unequal heights) and is irregularly attached with white particles, the white particles are indium simple substances, trivalent indium in the ITO is reduced into indium of the simple substances and oxygen is oxidized into oxygen to be released in the corrosion process, and compared with the previous EDX detection result, the content of indium elements in the abnormal area is increased and the content of oxygen elements is reduced.
