Description

How to make an LCD panel

technical field

The invention relates to a method for making a liquid crystal panel, in particular to a method for making a liquid crystal panel by utilizing polymer stable alignment technology.

Background technique

With the advancement of display technology, compared with traditional CRT displays, liquid crystal display (TFT-LCD) has become the main force in the display market due to its advantages of lightness, thinness, low radiation, and small size without occupying space. At the same time, it is widely used in various electronic products such as calculators, personal digital assistants (PDA), notebook computers, digital cameras, and mobile phones.

In response to the rapid development of liquid crystal display products, the competition among liquid crystal panel manufacturers is increasing day by day. The industry's active investment in research and development and the adoption of more advanced production equipment have led to a continuous reduction in the production cost of liquid crystal displays, which has further increased the demand for liquid crystal displays. In order to further expand the application fields and quality of liquid crystal displays, the current research focus of liquid crystal displays is mainly on how to increase the viewing angle and shorten the response time of the screen.

In order to meet the above requirements, the industry has developed a method for manufacturing liquid crystal panels using polymer stabilized alignment (PSA) technology.

This method is mainly to produce a high molecular polymer in the liquid crystal panel, so that the liquid crystal molecules have a pretilt angle under the influence of the high molecular polymer. Therefore, when the liquid crystal molecules are driven by the electric field, the liquid crystal molecules can be quickly deflected to an appropriate orientation, thereby shortening the response time of the liquid crystal panel. For a detailed description of this method, the basic structure of the liquid crystal panel can be introduced first.

The liquid crystal panel includes an upper substrate, a layer of liquid crystal molecules, and a lower substrate. The liquid crystal molecule layer is formed between the upper substrate and the lower substrate. A shared electrode is arranged between the liquid crystal molecule layer and the upper substrate.

Please refer to FIG. 1 . FIG. 1 is a top view of a unit pixel structure in a conventional polymer stabilized alignment liquid crystal panel. The pixel structure is mainly formed on the surface of the lower substrate. For each unit pixel 10 , its main components include a scan line 101 , a data line 102 , a thin film transistor 103 , a storage capacitor C _st and a pixel electrode 105 . The operation procedure of the unit pixel 10 is to input a scan signal through the scan line 101 to turn on the thin film transistor 103 , so that the voltage signal on the data line 102 is transmitted to the pixel electrode 105 . At the same time, the voltage signal input by the data line 102 will be retained in the storage capacitor 104 so as to keep the unit pixel 10 at a certain gray scale level during the interval of image data supply.

As shown in FIG. 1 , the shape of the pixel electrode 105 includes a plurality of strip patterns parallel to each other, and these strip patterns respectively extend toward four azimuth angles (ie, the fishbone pattern in the figure). When the unit pixel 10 works, the electric field generated between the pixel electrode 105 and the common electrode will make the liquid crystal molecules in the liquid crystal molecule layer deflect correspondingly according to the electric field. Due to the shape of the pixel electrode 105 , the liquid crystal molecules will respectively deflect toward the four azimuth angles, thereby forming the effect of four domains.

In order to shorten the response time of the liquid crystal panel, after the above-mentioned pixel electrodes 105 are manufactured, polymer stabilized alignment technology can be used, and a curing process can be performed to make the liquid crystal molecules have a fixed pretilt angle. Please refer to FIG. 2 . FIG. 2 is a schematic circuit diagram of the existing unit pixel 10 when performing a curing process, which includes the above-mentioned storage capacitor C _st and liquid crystal capacitor C _lc . Wherein, the liquid crystal capacitor _Clc is formed by the pixel electrode 105 and the common electrode. During the curing process, the common electrode is maintained at a certain potential level. In a preferred embodiment, the common electrode is maintained at a ground potential (V _ground ).

The curing procedure is to apply a curing voltage (V _curing ) to an electrode of the storage capacitor C _st after adding a monomer for polymer alignment to the liquid crystal molecular layer during the process of making the liquid crystal panel. At this time, the pixel electrode 105 has a coupling voltage (V _couple ) applied to the pixel electrode 105 due to capacitive coupling, so that each liquid crystal molecule is deflected to a predetermined angle, and at the same time, the above-mentioned monomers also follow the alignment direction of the liquid crystal molecule And arrange. Then, by using an ultraviolet light, the above monomers are polymerized into high molecular polymers, which are obliquely formed in the liquid crystal panel.

With this polymer stabilized alignment technology, the high molecular polymer can make the liquid crystal molecules have a pre-tilt angle, that is, the liquid crystal molecules will be tilted and arranged under the influence of the high molecular polymer when they are not driven by an electric field. Therefore, when the liquid crystal molecules are driven by the electric field, the liquid crystal molecules can be quickly deflected to an appropriate orientation, thereby shortening the response time of the liquid crystal panel.

In current polymer stabilized alignment (PSA) liquid crystal panels, the pixel electrode 105 is made of ITO material, and a fishbone pattern is produced by a lithography process, which can divide a single pixel into four domains. Although this design can greatly increase the contrast value and brightness value of the liquid crystal panel, and effectively shorten the response time. However, as the size of the liquid crystal panel increases, this design still cannot solve the problem of large viewing angle deviation, and cannot further reduce the phenomenon of insufficient color washout (color washout).

Please refer to FIG. 5 . FIG. 5 is a schematic circuit diagram of a unit pixel performing a curing procedure. From the schematic diagram of the circuit, the relational expressions of V ₁ =C _st1 /(C _st1 +C _lc1 )*V _curing1 and V ₂ =C _st2 /(C _st2 +C _lc2 )*V _curing2 can be deduced.

Before performing the curing process, in addition to first determining the first curing voltage _Vcuring1 applied to the second common electrode 324 and the second curing voltage _Vcuring2 applied to the third common electrode 334, it is also necessary to determine the voltage applied to the first common electrode 314. The magnitude of the voltage on it. Generally speaking, the voltage level of the first common electrode 314 can be maintained at the potential level (V _ground ) of the ground state.

first embodiment

When the ratio of the first storage capacitor _Cst1 to the first liquid crystal capacitor _Clc1 is not equal to the ratio of the second storage capacitor _Cst2 to the second liquid crystal capacitor _Clc2 , the method for manufacturing the liquid crystal panel further includes the following steps.

First, according to the relational formula of V ₁ =C _st1 /(C _st1 +C _lc1 )*V _curing1 , when the voltage V ₁ of the first pixel electrode 311 is to be equal to a coupling voltage V, it needs to be applied to the second shared electrode 324 The first curing voltage V _curing1 .

Next, according to the relational formula of V ₂ =C _st2 /(C _st2 +C _lc2 )*V _curing2 , when the voltage V ₂ of the second pixel electrode 321 is to be equal to the coupling voltage V, the voltage required to be applied to the third shared electrode 334 is generated. The second curing voltage V _curing2 .

That is to say, in the process of curing the alignment of liquid crystal molecules, the first curing voltage _Vcuring1 and the second curing voltage _Vcuring2 can be changed to appropriate voltage levels according to the above two relational expressions, and respectively applied to the second common electrode 324 and the third shared electrode 334, so that the ratio of the voltage V ₁ of the first pixel electrode 311 to the voltage V ₂ of the second pixel electrode 321 is approximately between 0.9 and 1.1, and more preferably, both are equal to a coupling voltage V (V ₁ =V ₂ =V).

In an embodiment, the capacitance values are as follows: C _st1 =0.1312pF, C _st2 =0.087pF, C _lc1 =C _lc2 =0.0396. When the first curing voltage V _curing1 =60V (volts) and the second curing voltage V _curing2 =44.5V (volts), the voltages of the two pixel electrodes V ₁ =V ₂ =14V (volts). In this way, by inputting two kinds of curing voltages, the voltages of the two pixel electrodes are approximately the same, and the occurrence of irregular liquid crystal alignment can be avoided.

Therefore, the ratio of the first storage capacitor _Cst1 to the first liquid crystal capacitor _Clc1 is not equal to the ratio of the second storage capacitor _Cst2 to the second liquid crystal capacitor _Clc2 . When the first curing voltage _Vcuring1 and the second curing voltage _Vcuring2 of different voltage levels are respectively applied to the second shared electrode 324 and the third shared electrode 334, the voltage _V1 of the first pixel electrode 311 and the second pixel electrode 311 can be The ratio of the voltage V ₂ of the electrode 321 is approximately between 0.9 and 1.1. More preferably, the voltage V ₁ of the first pixel electrode 311 is equal to the voltage V ₂ of the second pixel electrode 321 .

The advantage of this method is that it can flexibly adjust the curing voltage with different capacitance ratios. However, in the process of manufacturing the liquid crystal panel, since it is necessary to control the voltage application procedures of two different voltages, the manufacturing process becomes more complicated.

second embodiment

Considering the manufacturing process, in order to use the same curing voltage (V _curing1 =V _curing2 ) to achieve the same voltage of the two pixel electrodes (V ₁ =V ₂ ), it is necessary to adjust the first liquid crystal capacitor C _lc1 and the first liquid crystal capacitor. The proportional relationship among the storage capacitor C _st1 , the second liquid crystal capacitor C _lc2 and the second storage capacitor C _st2 .

It can be known from the aforementioned relational formula that, when the voltages of the two pixel electrodes are the same (V ₁ =V ₂ ) and the two curing voltages are the same (V _curing1 =V _curing2 ), the first storage capacitor C _st1 and the first liquid crystal capacitor C The ratio of _lc1 (C _st1 /C _lc1 ) must be equal to the ratio of the second storage capacitor C _st2 to the second liquid crystal capacitor C _lc2 (C _st2 /C _lc2 ), that is, satisfy C _st1 /C _lc1 = C _st2 /C _lc2 relation.

That is to say, when the ratio (C _st1 /C _lc1 ) of the first storage capacitor C _st1 to the first liquid crystal capacitor C _lc1 is equal to the ratio (C _st2 /C _lc2 ) of the second storage capacitor C _st2 to the second liquid crystal capacitor C _lc2 ), as long as the same curing voltage is applied to the second common electrode 324 and the third common electrode 334, that is, even if the first curing voltage _Vcuring1 is equal to the second curing voltage _Vcuring2 ( _Vcuring1 = _Vcuring2 ), the first pixel electrode The voltage V ₁ of 311 is still equal to the voltage V ₂ of the second pixel electrode (V ₁ =V ₂ ).

Therefore, in the process of making a liquid crystal panel, it is necessary to make the ratio of the first storage capacitor C _st1 to the first liquid crystal capacitor _Clc1 (C _st1 /C _lc1 ) equal to the ratio of the second storage capacitor C _st2 to the second liquid crystal capacitor _Clc2 (C _st2 /C _lc2 ). This effect can be achieved by the following steps.

For example, the size of the first capacitor electrode 323 and the second capacitor electrode 333 can be selected to be adjusted so that the first capacitor electrode 323 and the second capacitor electrode 333 have different areas respectively.

Alternatively, the size of the first pixel electrode 311 and the second pixel electrode 321 can be chosen to be changed so that the first pixel electrode 311 and the second pixel electrode 321 have different areas respectively. In addition, the size of the second shared electrode 324 and the third shared electrode 334 can also be selected to be changed so that the second shared electrode 324 and the third shared electrode 334 have different areas respectively.

By adjusting the area of the electrodes, the ratio of the first storage capacitor C _st1 to the first liquid crystal capacitor _Clc1 can be equal to the ratio of the second storage capacitor C _st2 to the second liquid crystal capacitor _Clc2 . In this case, the first curing voltage _Vcuring1 and the second curing voltage _Vcuring2 of the same voltage level can be applied to the second common electrode 324 and the third common electrode 334, and make the voltage V of the first pixel electrode 311 The ratio of ₁ to the voltage V ₂ of the second pixel electrode 321 is approximately between 0.9 and 1.1. More preferably, the voltage V ₁ of the first pixel electrode 311 is equal to the voltage V ₂ of the second pixel electrode 321 .

As mentioned above, each unit pixel 30 of the liquid crystal panel of the present invention has a first pixel electrode 311 and a second pixel electrode 321 that are independent from each other. Please refer to FIG. 3 , wherein the first pixel electrode 311 has four subregions, and part of the first pixel electrode 311 in each subregion is composed of a plurality of strip patterns parallel to each other, and these strip patterns are along the same direction. Extended distribution.

The second pixel electrode 321 may also have four sub-regions, and part of the second pixel electrode 321 in each sub-region is composed of a plurality of strip patterns parallel to each other, and these strip patterns extend along the same direction.

In a preferred embodiment, the azimuth angles of the extension directions of the elongated patterns located in the above four divisions are approximately 40-50 degrees, 130-140 degrees, 220-230 degrees, and 310-320 degrees respectively. . Therefore, the pattern distribution presented by the first pixel electrode 311 and the second pixel electrode 321 is similar to a fishbone pattern.

Please refer to FIG. 6 . FIG. 6 is a representation diagram of a unit pixel image in the present invention. As shown in the figure, no matter whether the method of the first embodiment or the second embodiment is applied, the ratio of the voltage V ₁ of the first pixel electrode 311 to the voltage V ₂ of the second pixel electrode 321 can be between about 0.9 and 1.1, more preferably, the voltage V ₁ of the first pixel electrode 311 is equal to the voltage V ₂ of the second pixel electrode 321 . In this way, after the curing process, the alignment of the liquid crystal molecules will be more uniform and orderly. There will be no disclination lines in a unit pixel, so that the liquid crystal panel has better imaging quality.

Although the present invention is described above with preferred embodiments, it is not intended to limit the spirit and entity of the creation, but only the above embodiments. Therefore, any modifications made without departing from the spirit and scope of the creation should be included within the scope of the patent application for the present invention.
