所述第一透明电极层122和所述第二透明电极层124之间设置有多个所述液晶分子142，每个所述液晶分子142包括长轴L1和短轴L2，所述长轴L1和所述短轴L2相互垂直，当所述第一透明电极层122和所述第二透明电极层124之间未施加电压时，多个所述液晶分子142以原始状态自由排列。A plurality of the liquid crystal molecules 142 are arranged between the first transparent electrode layer 122 and the second transparent electrode layer 124, and each of the liquid crystal molecules 142 includes a long axis L1 and a short axis L2. The long axis L1 It is perpendicular to the short axis L2, and when no voltage is applied between the first transparent electrode layer 122 and the second transparent electrode layer 124, a plurality of the liquid crystal molecules 142 are freely arranged in the original state.
当所述第一透明电极层122和所述第二透明电极层124之间施加一定电压时，多个所述液晶分子142同时受到电场的影响而发生翻转，各个液晶分子142靠近电源正极的一端向正极偏转，靠近电源负极的一端向负极偏转，例如在未施加电压时，某个液晶分子142的长轴L1的延长线与所述第一透明电极层122的夹角为初始夹角，例如为45度，当施加电压时，液晶分子受到电场的作用发生偏转，液晶分子142的长轴L1的延长线与所述第一透明电极层122的夹角变大，例如变成60度，当施加的电压稳定时，液晶分子会保持一定的夹角不变。可以理解的是，随着所述第一透明电极层122和所述第二透明电极层124之间施加的电压逐渐增大，该夹角逐渐增大最终变成垂直于电极层的90度。从而多个所述液晶分子142在电极层12的控制下同时连续发生偏转从而持续改变偏振光的偏振方向，并且经由多个所述液晶分子142调整的偏振光的偏振方向为连续变化，所述显示面板的出光面出射的偏振光为线偏振光，多个所述液晶分子可以将线偏振光在椭圆偏振光及线偏振光之间调整。When a certain voltage is applied between the first transparent electrode layer 122 and the second transparent electrode layer 124, a plurality of the liquid crystal molecules 142 are simultaneously affected by the electric field and flipped, and each liquid crystal molecule 142 is close to one end of the positive electrode of the power supply. It is deflected toward the positive electrode, and the end close to the negative electrode of the power supply is deflected toward the negative electrode. For example, when no voltage is applied, the angle between the extension of the long axis L1 of a certain liquid crystal molecule 142 and the first transparent electrode layer 122 is the initial angle, for example, When a voltage is applied, the liquid crystal molecules are deflected under the action of the electric field, and the angle between the extension of the long axis L1 of the liquid crystal molecules 142 and the first transparent electrode layer 122 becomes larger, for example, 60 degrees. When the applied voltage is stable, the liquid crystal molecules will maintain a certain angle unchanged. It can be understood that as the voltage applied between the first transparent electrode layer 122 and the second transparent electrode layer 124 gradually increases, the included angle gradually increases and eventually becomes 90 degrees perpendicular to the electrode layer. Therefore, the plurality of liquid crystal molecules 142 are continuously deflected at the same time under the control of the electrode layer 12 to continuously change the polarization direction of the polarized light, and the polarization direction of the polarized light adjusted by the plurality of liquid crystal molecules 142 is continuously changed. The polarized light emitted from the light exit surface of the display panel is linearly polarized light, and a plurality of the liquid crystal molecules can adjust the linearly polarized light between elliptically polarized light and linearly polarized light.
对所述第一透明电极层122和所述第二透明电极层124施加不同的电压信号，使所述第一透明电极层122和所述第二透明电极层124之间产生变化的电场，然后利用所述液晶分子142的“电偶极矩”现象，使多个所述液晶分子142同时随着电场的变化而翻转，由于所述液晶分子142的长轴L1和短轴L2方向的光折射率不同，所述液晶分子142具有“旋光效应”，进而利用液晶分子142的“旋光效应”使入射光的偏振方向发生不断发生变化，由此使穿过多个所述液晶分子142的出射光更加接近自然光，不易使人眼产生干涩及疲劳等不良反应，保护人眼的健康。Different voltage signals are applied to the first transparent electrode layer 122 and the second transparent electrode layer 124 to generate a varying electric field between the first transparent electrode layer 122 and the second transparent electrode layer 124, and then Utilizing the "electric dipole moment" phenomenon of the liquid crystal molecules 142, a plurality of the liquid crystal molecules 142 are flipped simultaneously with the change of the electric field, due to the light refraction in the directions of the long axis L1 and the short axis L2 of the liquid crystal molecules 142 With different rates, the liquid crystal molecules 142 have an "optical rotation effect", and the "optical rotation effect" of the liquid crystal molecules 142 is used to continuously change the polarization direction of the incident light, thereby making the emitted light passing through the plurality of liquid crystal molecules 142 Closer to natural light, it is not easy to cause adverse reactions such as dryness and fatigue to the human eye, and protects the health of the human eye.
请一并参阅图2和图3，本申请一些实施例提供的液晶薄膜100a与图1所示的液晶薄膜100基本相同，区别在于所述液晶薄膜100a包括基 板18、电极层12a和液晶分子142a，所述电极层12a为一层透明电极层，所述基板18作为所述电极层12a和所述液晶分子142a的承载体，所述基板18上层叠有所述电极层12a，多个液晶分子142a设置于所述基板18和所述电极层12a之间，所述电极层12a分割为若干长条形透明电极层区块121，所述若干所述透明电极层区块121相互平行且间隔一定距离，每两个相邻的所述透明电极层区块121中，一个所述透明电极层区块121电连接于所述电源16的正极，另一个所述透明电极层区块121电连接于所述电源16的负极。2 and 3 together, the liquid crystal film 100a provided by some embodiments of the present application is basically the same as the liquid crystal film 100 shown in FIG. 1, except that the liquid crystal film 100a includes a substrate 18, an electrode layer 12a and liquid crystal molecules 142a The electrode layer 12a is a transparent electrode layer, the substrate 18 serves as a carrier for the electrode layer 12a and the liquid crystal molecules 142a, the electrode layer 12a is laminated on the substrate 18, and a plurality of liquid crystal molecules 142a is disposed between the substrate 18 and the electrode layer 12a. The electrode layer 12a is divided into a plurality of elongated transparent electrode layer sections 121, and the plurality of transparent electrode layer sections 121 are parallel to each other with a certain interval. For every two adjacent transparent electrode layer sections 121, one of the transparent electrode layer sections 121 is electrically connected to the positive electrode of the power supply 16, and the other transparent electrode layer section 121 is electrically connected to The negative pole of the power supply 16.
每个所述液晶分子142a包括长轴L1和短轴L2，所述长轴L1和所述短轴L2相互垂直，当所述第一透明电极层122和所述第二透明电极层124之间未施加电压时，每个所述液晶分子142a以原始状态自由排列，当每两个相邻所述透明电极层区块121之间施加一定电压时，多个所述液晶分子142a发生水平旋转，即每个所述液晶分子142a的长轴L1的一端被正极吸引而向正极方向偏转，另一方被负极吸引而向负极方向偏转。当施加的电压稳定时，每个所述液晶分子142a相对于电极方向的偏转趋于一致，且随着每两个相邻所述透明电极层区块121之间施加的电压逐渐增大，所述偏转角度逐渐增大，最终液晶分子的长轴方向与电极层垂直，此时，每两个相邻所述透明电极层区块121之间施加的电压继续增大也不再偏转，可以理解的是，此时，将每两个相邻所述透明电极层区块121之间施加的电压逐渐变小，所述液晶分子相对于电极方向的偏转也会逐渐变小。Each of the liquid crystal molecules 142a includes a long axis L1 and a short axis L2. The long axis L1 and the short axis L2 are perpendicular to each other. When the first transparent electrode layer 122 and the second transparent electrode layer 124 are between the When no voltage is applied, each liquid crystal molecule 142a is freely arranged in its original state. When a certain voltage is applied between two adjacent transparent electrode layer sections 121, a plurality of liquid crystal molecules 142a rotate horizontally. That is, one end of the long axis L1 of each of the liquid crystal molecules 142a is attracted by the positive electrode and deflected toward the positive electrode, and the other is attracted by the negative electrode and deflected toward the negative electrode. When the applied voltage is stable, the deflection of each liquid crystal molecule 142a with respect to the electrode direction tends to be uniform, and as the voltage applied between every two adjacent transparent electrode layer sections 121 gradually increases, The deflection angle gradually increases, and finally the long axis direction of the liquid crystal molecules is perpendicular to the electrode layer. At this time, the voltage applied between every two adjacent transparent electrode layer sections 121 continues to increase and no longer deflects. It is understandable However, at this time, the voltage applied between every two adjacent transparent electrode layer sections 121 gradually decreases, and the deflection of the liquid crystal molecules with respect to the electrode direction will gradually decrease.
对每两个相邻的所述透明电极层区块121之间施加不同的电压信号，使所述每两个相邻的所述透明电极层区块121之间产生的变化的电场，利用所述液晶分子142a的“电偶极矩”现象，使所述液晶分子142a随着电场的变化而水平翻转，由于所述液晶分子142a的长轴L1和短轴 L2方向的光折射率不同，所述液晶分子142a具有“旋光效应”，进而利用液晶分子142a的“旋光效应”使入射光的偏振方向发生不断发生变化，由此使穿过所述液晶分子142a的出射光更加接近自然光，不易使人眼产生干涩及疲劳等不良反应，保护人眼的健康。A different voltage signal is applied between each two adjacent transparent electrode layer sections 121, so that the changing electric field generated between each two adjacent transparent electrode layer sections 121 utilizes all The "electric dipole moment" phenomenon of the liquid crystal molecule 142a causes the liquid crystal molecule 142a to flip horizontally with the change of the electric field. Because the long axis L1 and the short axis L2 of the liquid crystal molecule 142a have different light refractive indexes, The liquid crystal molecules 142a have an "optical rotation effect", and the "optical rotation effect" of the liquid crystal molecules 142a is used to continuously change the polarization direction of the incident light, thereby making the emitted light passing through the liquid crystal molecules 142a closer to natural light, which is not easy to cause Human eyes produce adverse reactions such as dryness and fatigue, which protect the health of human eyes.
