Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, the novel electronic transparent screen of the present invention includes a frame 1, and a TFT2, an ink plate 3 and a driving device respectively fixed in the frame 1, where the TFT2 is transparent, the ink plate 3 includes a glass clamping plate 31 and a charged ink 32 encapsulated in the glass clamping plate 31, and the driving device is disposed at a position of the frame 1. The charged ink 32 itself has positive or negative charges, and the driving device supplies power to the TFT2 to make the TFT2 generate current, so that the charged ink 32 moves to a desired position under the action of the TFT2 according to the principle of opposite attraction and like repulsion. For example, when the novel electronic transparent screen needs to show a light-transmitting state, the TFT2 generates charges with the same polarity as that of the charges of the charged ink 32, so that the charged ink 32 moves to the edge (BM area) of the glass clamping plate 31 under the action of the TFT2, and light passes through the TFT2 and the glass clamping plate 31, so that the novel electronic transparent screen shows a light-transmitting state; when the novel electronic transparent screen needs to present an opaque state, the TFT2 generates charges with a polarity opposite to that of the charges of the charged ink 32, so that the charged ink 32 moves to the cover glass clamp plate 31 (non-BM area) under the action of the TFT2, and the charged ink 32 blocks light, thereby presenting the opaque state to the novel electronic transparent screen.
The opaque state of the novel electronic transparent screen may be, for example, a completely opaque state, or may be, for example, a semi-opaque state. The amount of the charged ink 32 in the cover glass clamp plate 31 can be adjusted according to the voltage of the TFT2, so that the novel electronic transparent screen can be in a completely opaque state or a semi-opaque state. In addition, the position of the charged ink 32 of the cover glass clamp plate 31 can be adjusted according to the power supply position of the TFT2, so that the novel electronic transparent screen can present a pattern state (black or white pattern), and the novel electronic transparent screen can be applied to a vehicle head-up display and the like.
In the novel electronic transparent screen, the TFT2 drives the charged ink 32, the power supply position and the voltage distribution of the TFT2 are uniform, and the free movement of the charged ink 32 can be realized; the electric quantity required by the TFT2 when driving the charged ink 32 to move is extremely small, and compared with a transparent liquid crystal display screen, the electric-powered ink-jet display screen is ultra-electricity-saving, and the use environment of the charged ink 32 is less limited, and the electric-powered ink-jet display screen is long in service life and simple in structure. The novel electronic transparent screen can be applied to vehicle-mounted head-up displays, intelligent vehicle windows, household window glass, glass doors of household appliances and the like. As shown in fig. 2, when the novel electronic transparent screen is used as, for example, a household window glass, the whole glass is in a grid structure enclosed by a plurality of frames 1, an ink plate 3 and a TFT2 are respectively arranged in each grid, and each TFT2 is controlled by the same driving device, so that the migration length of the charged ink 32 in each novel electronic transparent screen is reduced, and the novel electronic transparent screen can smoothly realize the switching between the transparent state and the non-transparent state.
Frame 1 can be white or black opaque plastics frame 1, and the limit portion of glass splint 31 inlays and establishes in frame 1, when electrified printing ink 32 removes the limit portion to glass splint 31, shelters from electrified printing ink 32 by frame 1, improves the aesthetic property of novel electron transparent screen. The material of the charged ink 32 may be, for example, graphene, and the color may be black or white opaque. The thickness of the gap between the glass clamping plates 31 of the ink plate 3 can be specifically set according to requirements.
The TFT2 includes a substrate fixed in the frame 1, and a transparent gate layer and a source drain layer formed on the glass substrate in sequence, in which the gate layer constitutes a gate line and the source drain layer constitutes a data line. The driving device includes a gate driver connected to the gate line of the TFT2, a data driver connected to the data line of the TFT2, and a clock controller connected to the gate driver and the data driver. The clock controller controls the power supply voltage and the power supply duration of the gate driver and the data driver, so that the charged ink 32 moves to the glass clamping plate 31 under the action of the voltage to block at least part of light passing through the glass clamping plate 31 or moves to the edge of the glass clamping plate 31 to enable all the light to pass through the glass clamping plate 31.
Further, the polarity of the power supply voltage provided by the gate driver is opposite to the polarity of the power supply voltage provided by the data driver, and during the start time of the charged ink 32, the gate driver and the data driver operate alternately, that is, the driving device first provides the charged ink 32 with the start voltage with the opposite polarity and alternately. With such an arrangement, the gate driver provides the on-voltage for the charged ink 32, so as to reduce the problem that the charged ink 32 is polarized under the action of the same polarity voltage for a long time, that is, when the novel electronic transparent screen is in the non-transparent state for a long time and is switched from the non-transparent state to the transparent state, if only the polarity of the power supply voltage is switched, the charged ink 32 cannot be smoothly moved to the edge of the glass clamping plate 31 due to the polarization problem.
It should be noted that the starting time of the charged ink 32 can be specifically set according to the requirement, for example, 1s or 2s, and the specific starting time can be specifically set according to the quantity of the charged ink 32 or other parameters.
Further, as shown in fig. 3, where G0-G241 denote gate lines, D1-D14 denote data lines, the voltage value of the power supply voltage supplied by the gate driver is greater than that of the power supply voltage supplied by the data driver, and the polarity of the charge generated by the power supply voltage supplied by the gate driver is the same as that of the charged ink 32. The ratio of the voltage value of the supply voltage of the gate driver to the voltage value of the supply voltage of the data driver is 1.5-2: 1. The single power supply time length of the gate driver is shorter than that of the data driver, i.e. in one time sequence T generated by the clock controller, the power supply time length Ta of the gate driver is shorter than that of the data driver Tb. In one example, the ratio of the single power-on period of the gate driver to the single power-on period of the data driver is 1:3-5, and further, the power-on period Ta of the gate driver is 0.2-0.3s in a single timing. So set up, the problem that electrified printing ink 32 is by the polarization can furthest's solution improves the use experience of novel electron transparent screen.
While the present invention has been described with reference to the embodiments shown in the drawings, the present invention is not limited to the embodiments, which are illustrative and not restrictive, and it will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
