Referring to fig. 1, an embodiment of the present disclosure provides a liquid crystal display panel, which includes a first substrate 1, a second substrate 2, a liquid crystal layer 3, a first nanograting 4, and a second nanograting 5. The first substrate 1 and the second substrate 2 are disposed opposite to each other, the liquid crystal layer 3 is disposed between the first substrate 1 and the second substrate 2, and the first substrate 1 and the second substrate 2 are transparent substrates, preferably glass substrates.
The first nanometer grating 4 and the second nanometer grating 5 are distributed on two sides of the liquid crystal layer 3 as a polarizing layer, the first nanometer grating 4 is arranged on the first substrate 1, and the second nanometer grating 5 is arranged on the second substrate 2. As shown in fig. 2, the first nanograting 4 and the second nanograting 5 are perpendicular to each other, so that a light polarization function is realized, the manufacturing cost is reduced, and the thickness of the display is reduced. The first nano-grating 4 and the second nano-grating 5 are both set as metal nano-gratings. The channels and the intervals of the metal nano-gratings are all in the nano-scale, and can be set based on the requirement of the polarization function, which is not specifically limited in this embodiment.
In addition, a part of the channels in the first nanograting 4 are set as touch transmitting electrodes 41(Tx), the touch transmitting electrodes 41 are used for connecting touch transmitting signals, a part of the channels in the second nanograting 5 are set as touch receiving electrodes 51(Rx), and the touch receiving electrodes 51 are used for connecting touch receiving signals. The touch electrodes only occupy few channels of all the nano-gratings of the first nano-grating 4 and the second nano-grating 5, and the touch electrodes include a touch transmitting electrode 41 and a touch receiving electrode 51. The nano-grating channel of the non-touch electrode for polarizing only performs a polarizing function and does not externally connect a signal; the touch electrode needs to be externally connected with a transmission and receiving signal, mainly has a touch function, is a conductive medium, and has a polarization effect. The touch electrode routing is generally set to be rhombic or can be set to be a straight line, the rhombic routing is the conventional external hanging design, but the width occupies space, and partial loss of polarization degree exists; and the linear wiring design can greatly improve the polarization degree. In this embodiment, the touch electrode trace is preferably a straight line.
In the embodiment, the polarization function is realized by replacing the polaroid with the nano-grating, the conventional polaroid is not needed, and meanwhile, part of the nano-grating is also a touch electrode and is externally connected with a transmission signal and a receiving signal, so that touch integration and structure simplification are realized.
In one embodiment, the channel spacing of the touch transmitting electrodes 41 and the touch receiving electrodes 51 is set based on signal transmission requirements such as signal-to-noise ratio, and therefore, the channel spacing may be set at uniform intervals or at non-uniform intervals.
In one embodiment, the channel spacing period of the touch transmitting electrode 41 is set to be an integer multiple of the grating period of the first nanograting 4, and the channel spacing period of the touch receiving electrode 51 is set to be an integer multiple of the grating period of the second nanograting 5. The channel interval period of the touch transmitting electrode 41 and the channel interval period of the touch receiving electrode 51 may be the same or different. The longer the channel interval period of the touch transmitting electrode 41 and the channel interval period of the touch receiving electrode 51, the better the signal transmission effect.
Taking the way of calculating the channel interval period of the touch receiving electrode 51 as an example, as shown in fig. 3, LRx=NL0,LRxIs the channel interval period of the touch receiving electrode 51, N is a positive integer, L0The grating period of the second nano-grating 5, for example, the Rx (touch control receiving electrode 51) channel interval period LRx6.5mm, the grating period L of the second nanograting 50250nm, then N26000. That is, the first nanograting 4 has one touch signal input (touch receiving electrode 51) every 26000 grating periods. Tx (touch transmission electrode 41) is the same as Rx.
In one embodiment, since the channels in the first nanograting 4 and the second nanograting 5 are on the nanometer scale, and the touch electrode is typically on the micrometer scale, the width of the channel set as the touch transmitting electrode 41 in the first nanograting 4 is greater than the width of the channel set as the non-touch transmitting electrode 41, the width of the channel set as the touch receiving electrode 51 in the second nanograting 5 is greater than the width of the channel set as the non-touch receiving electrode 51, and the width direction is the extending direction of the grating interval arrangement. In addition, in order to facilitate distinguishing the channels of the touch electrode and the non-touch electrode in the first nanograting 4 and the second nanograting 5, the height of the channel of the touch electrode may be set to be lower than the height of the channel of the non-touch electrode.
In one embodiment, the liquid crystal display panel further includes a first protective layer 6, and the first protective layer 6 plays a role of isolating and protecting external substances such as air, moisture, and the like at the outermost layer of the entire liquid crystal display panel. Since the first substrate 1 is a transparent glass substrate, the relative positions of the first substrate 1 and the first nanograting 4 have no influence. As shown in fig. 4 and 5, the first nanograting layer 4 is disposed between the first substrate 1 and the liquid crystal layer 3, and the first protective layer 6 is disposed on a side of the first substrate 1 away from the liquid crystal layer 3. Alternatively, as shown in fig. 6 and 7, the first nanograting 4 is disposed on the first substrate 1 on a side away from the liquid crystal layer 3, the first protective layer 6 is disposed on the first nanograting 4, and the first nanograting 4 is disposed between the first substrate 1 and the first protective layer 6.
Further, the first protective layer 6 is provided as a protective film or coating. The coating is generally a layer of material with higher stability, which is coated on the surface of the coating and used for isolating air, moisture and other external substances, and certainly has the function of protecting the damage. The coating material process is generally in a coating form, and this embodiment is not particularly limited. The protective film is added by attaching a layer of protective film, the protective film is generally made of PET (polyethylene terephthalate) or other applicable materials, the hardness can be matched according to application requirements, and the application is not limited.
In one embodiment, the liquid crystal display panel further includes a second protective layer 7, and the second protective layer 7 plays a role in isolating and protecting external substances such as air and moisture in the outermost layer of the entire liquid crystal display panel. Since the second substrate 2 is a transparent glass substrate, the relative position between the second substrate 2 and the second nanograting 5 has no influence. As shown in fig. 5 and 7, the second nanograting layer 5 is disposed between the second substrate 2 and the liquid crystal layer 3, and the second protective layer 7 is disposed on a side of the second substrate 2 away from the liquid crystal layer 3. Alternatively, as shown in fig. 4 and fig. 6, the second nanograting 5 is disposed on the second substrate 2 at a side away from the liquid crystal layer 3, the second protective layer 7 is disposed on the second nanograting 5, and the second nanograting 5 is disposed between the second substrate 2 and the second protective layer 7.
Furthermore, the second protective layer 7 is provided as a protective film or coating. The second coating is generally a two-layer material with higher stability, which is coated on the second coating and used for isolating air, moisture and other external substances, and certainly has the function of protecting the damage. The second protective layer 7 needs to have two levels of wear resistance and hardness because the touch screen can be touched by a human finger or a stylus. Without a coating or protective layer, the surface is easily scratched, causing problems of poor display effect or functional failure. The coating material process is generally in a coating form, and the coating form and the embodiment of the coating material are not particularly limited. The addition of the protective film is to attach two protective films, or other applicable materials, and the hardness can be matched according to application requirements, and is not particularly limited.
The polarizer in the embodiment realizes the polarization function by replacing the metal nano grating, the metal nano grating is also a touch electrode, the required number of channels is selected according to the touch precision, conventional polarizers and cover plates are not needed, only one layer of protective layer coating or protective film is needed, and then touch integration and structural simplification are realized, the added value of products is high, the cost advantage is obvious, and the benefit is improved.
