Description
Technical Field
The invention relates to the field of 3D display devices, in particular to a substrate assembly, a 2D/3D switchable display panel and a 2D/3D switchable display device.
Background
At present, the glass substrate used by the 3D Switch Cell (2D and 3D switching unit) is an ITO glass substrate, after the upper and lower layers of ITO glass substrates are pressed into a box, the ITO glass substrate between the upper and lower substrates will form a similar conductive capacitor, when the power is on, the upper and lower substrates will have a potential difference to form an electric field required by the design, so as to control the liquid crystal molecules between the upper and lower substrates to turn over, which is a necessary item for the design.
However, the upper and lower substrates of the similar capacitor are coated on the whole surface of ITO, and because the existing box cannot be completely sealed after being pressed (the step edge cannot be Cut on Seal), the area inside the sealing frame (AA area) is a design effective area, and meanwhile, the area outside the sealing frame is exposed in air, when a reliability test is performed on a THB project, the 'ineffective area' outside the sealing area has two factors: ITO (conductive film) is in contact with air (with water vapor); when the upper substrate and the lower substrate are electrified, the upper substrate and the lower substrate on the outer edge of the sealing frame have potential difference (alternating current electric field), the upper substrate and the lower substrate are influenced by the electric field and water vapor, electrochemical corrosion occurs, electric signal transmission is influenced, and even liquid crystal molecules are abnormally overturned.
The existing solutions at present are: before the single-side substrate on the Spacer side is formed into a box, an isolation frame is arranged in a Laser (Laser) mode to isolate an invalid region and an effective region outside an AA region, the design scheme can completely improve the ITO corrosion phenomenon at the edge position of a non-step edge of a product, and after the Laser frame is isolated, the upper substrate and the lower substrate at the position of the invalid region outside the Laser frame at the edge of the substrate have no potential difference, so that the electrochemical corrosion reaction is avoided.
However, in the above improved design, the electrochemical corrosion phenomenon still occurs during the actual use, because when the FPC is soldered at one side, it is required to input voltages with different magnitudes and directions to form the potential difference between the upper and lower substrates, and the design requires that the a contact 11 ' and the B contact 12 ' of the lower substrate 10 ' are soldered separately and different electrical signals are input separately at both ends (as shown in fig. 1 and 2): the A connection point 11 'inputs PMW signal, and is conducted with the upper substrate 20' side through the metal conductive part, the B connection point 12 'directly inputs GND signal, and is directly input into the AA area (effective area in the isolation frame) on the lower substrate 10' side through the 'opening' of the isolation frame 13 ', thus the AA area has PMW and GND signals respectively input from the A connection point 11' and the B connection point 12 'on the two sides of the isolation frame 13', then the difference of PMW and GND signals is controlled to realize that the 'effective area' of the upper and lower substrates has artificial control potential difference, a controllable electric field is formed, whether the liquid crystal molecules are turned over or not (electrified or not) is controlled according to the artificial will, the absolute isolation frame 13 'on the lower substrate side can not completely seal the opening is realized by switching between 2D and 3D modes, namely when the voltage is input by FPC, when the metal conductive part is normally conducted, the A connection point 21' on the upper, because the a contact 21 ' and the B contact 22 ' on the upper substrate 20 ' side are at the same potential, the B contact 22 ' on the upper substrate 20 ' side and the a contact 11 ' on the lower substrate 10 ' side are at the same potential, and because a voltage difference exists between the a contact 11 ' and the B contact 12 ', a voltage difference exists between the B contact 12 ' and the B contact 22 ', and when moisture exists, the B contact is directly exposed in the external environment, so that the electrochemical corrosion phenomenon occurs.
