Description

monitor

This invention relates to a display, and more particularly to a highly reliable display.

In recent years, with the maturity of optoelectronic technology and semiconductor manufacturing technology, the flat panel display has been booming. Among them, liquid crystal displays are based on their low voltage operation, no radiation scattering, light weight and small size. Replacing the traditional cathode ray tube display has become the mainstream of display products in recent years. A conventional liquid crystal display is, for example, a liquid crystal display using a germanium-based liquid crystal panel (hereinafter referred to as an LCOS panel).

In the LCOS panel, it is mainly composed of a substrate made of a germanium wafer and a counter substrate made of a glass material. The LCOS panel replaces the thin film transistor used in the conventional liquid crystal panel by using a MOS transistor. The LCOS panel is a reflective liquid crystal display panel in which the pixel electrode of the panel is made of a metal material. In addition, since the metal pixel electrode covers almost the entire pixel area (especially the MOS transistor), the LCOS panel is superior in image display as compared with the conventional liquid crystal panel.

In general, in the conventional LCOS panel process, an alignment film is coated on a tantalum wafer by spin coating. Therefore, the alignment film is uniformly distributed on the germanium wafer. In this way, the sealant must be coated on the alignment film. Under this structure, the moisture absorbing alignment film will be in contact with the external environment, so that the external water vapor enters the LCOS through the alignment film. In the panel, the problem of poor display is caused.

First embodiment

1 is a schematic cross-sectional view of a display according to a first embodiment of the present invention. Referring to FIG. 1 , the display 100 of the present embodiment includes a first substrate 110 , a second substrate 120 opposite to the first substrate 110 , a sealant 130 between the first substrate 110 and the second substrate 120 , and a liquid crystal layer 140 . And a first alignment film 150. The first substrate 110, the second substrate 120 and the sealant 130 surround the liquid crystal layer 140. The sealant 130 of this embodiment is used to bond the first substrate 110 and the second substrate 120. The sealant 130 of this embodiment may be a heat curing adhesive, a UV curable adhesive, or other suitable type of adhesive. The liquid crystal layer 140 of this embodiment is used as a light valve, thereby enabling the display 100 to display a picture. The liquid crystal material selected for the liquid crystal layer 140 of the present embodiment may depend on actual needs and design. For example, the liquid crystal material in the liquid crystal layer 140 may be a twisted nematic liquid crystal or other suitable kind of liquid crystal.

The first substrate 110 of this embodiment has a first display area 110a and a first sealant coating area 110b surrounding the first display area 110a. In the present embodiment, the first display area 110a refers to a region in the first substrate 110 where a picture can be displayed, and the first sealant application area 110b refers to a region where the sealant 130 is coated on the first substrate 110. The first substrate 110 further has a first recess H1. The first recess H1 is located at least in a region 110c between the first display region 110a and the first sealant-coated region 110b. In the present embodiment, the first recess H1 may be located in the first display area 110a and the area 110c. Further, the first recess H1 of the embodiment is surrounded by the sealant 130 and covers the entire first range. The display area 110a and a part of the area 110c.

It is worth mentioning that the first recess H1 of the embodiment is used to limit the distribution range of the first alignment film 150. The structure of the first recess H1 is combined with the dropping type alignment film (inject PI) to make the sealant 130 difficult to coat on the first alignment film 150. As a result, the external moisture is less likely to enter the display 100 via the first alignment film 150, thereby affecting the reliability of the display 100. In the present invention, the structure of the first substrate having the first recess can be varied. Any first substrate having the first recess can limit the distribution range of the first alignment film, thereby achieving the purpose of improving the reliability of the display. The second embodiment of the present invention is illustrative of the structure of the first substrate having the first recess of the present invention, but the invention is not limited thereto.

In the embodiment, the first substrate 110 includes a germanium substrate 112, a pixel electrode layer 114, and a first protective pattern layer 116. The crucible substrate 112 has a plurality of active elements 112a arranged in an array. The germanium substrate 112 includes a germanium wafer. The active device 112a is, for example, a metal oxide semiconductor transistor or other suitable active device. The pixel electrode layer 114 is disposed on the crucible substrate 112. The pixel electrode layer 114 has a plurality of pixel electrodes 114a disposed in the first display region 110a. The pixel electrode 114a is electrically connected to the active element 112a. The material of the pixel electrode 114a may be aluminum (Al). The first protective pattern layer 116 is disposed between the sealant 130 and the pixel electrode layer 114.

In the embodiment, the first protection pattern 116 layer surrounds the first alignment film 150, and the sealant 130 may directly bond with the first protection pattern layer 116. Through the above arrangement, the first alignment film 150 does not come into contact with the external environment, and therefore the external moisture does not easily enter the display 100 through the first alignment film 150, thereby affecting the reliability of the display 100.

The second substrate 120 of the embodiment has a second display region 120a corresponding to the first display region 110a and a second sealant coating region 120b corresponding to the first sealant coating region 110b.

The second sealant coating zone 120b may be aligned with the first sealant coating zone 110b. The second substrate 120 of the present embodiment may selectively have a second recess H2. The second recess H2 is located at least in the region 120c between the second display region 120a and the second sealant-coated region 120b. Region 120c can be aligned with region 110c. In the present embodiment, the second recess H2 may be located in the second display area 120a and the area 120c. In other words, this implementation For example, the second recess H2 may be surrounded by the sealant 130, and the second recess H2 may cover the entire second display area 120a and a partial area 120c.

The display 100 of the present embodiment may further include a second alignment film 160. The second alignment film 160 is disposed between the second substrate 120 and the liquid crystal layer 140 and filled in the second recess H2. Similar to the first recess H1, the second recess H2 of the present embodiment is for limiting the distribution range of the second alignment film 160. The structure of the second recess H2 is combined with the dropping type alignment film (inject PI) to make the sealant 130 difficult to coat on the second alignment film 160. As a result, the external moisture is less likely to enter the display 100 via the second alignment film 160, thereby affecting the reliability of the display 100. In the present invention, the structure of the second substrate having the second recess can be varied. Any second substrate having the second recess can limit the distribution range of the second alignment film, thereby achieving the purpose of improving the reliability of the display. The second embodiment of the present invention is illustrative of the structure of the second substrate having the second recess of the present invention, but the invention is not limited thereto.

In the embodiment, the second substrate 120 includes a light transmissive substrate 122 , a light shielding pattern layer 124 , and a light transmissive conductive layer 126 . The light shielding pattern layer 124 is disposed between the light transmitting substrate 122 and the sealant 130. The light shielding pattern layer 124 covers the sealant 130 and exposes the second display area 120a. In the present embodiment, the second display area 120a may refer to a region of the second substrate 120 that overlaps the pixel electrode 114a. The light-transmitting conductive layer 126 is disposed between the light-transmitting substrate 122 and the second alignment film 160 and filled in the second recess H2. The second recess H2 may be located in the light shielding pattern layer 124 and may overlap the second display region 120a. In other words, the second recess H2 of the embodiment can be formed by the light shielding pattern layer 124. In the embodiment, the light shielding pattern layer 124 surrounds the second alignment film 160, and the sealant 130 is overlaid on the light shielding pattern layer 124. Moreover, the sealant 130 can be directly bonded to the light-transmitting conductive layer 126. Therefore, the second alignment film 160 does not come into contact with the external environment, and the external moisture does not easily enter the display 100 through the second alignment film 160, thereby affecting the reliability of the display 100. In addition, it should be noted that the present invention does not limit that both the first substrate and the second substrate need to have a recess, and at least one of the first substrate and the second substrate has the recess, so that the reliability of the display can be improved.

Second embodiment

2 is a cross-sectional view of a display according to a second embodiment of the present invention. Referring to FIG. 2, the display 100A of the present embodiment is similar to the display 100 of the first embodiment, and therefore the same elements are denoted by the same reference numerals.

The area covered by the first protective pattern layer 116A of the present embodiment is different from the first protective pattern layer 116 of the first embodiment. The second substrate 120A of the embodiment further includes a second protection pattern layer 128. Further, the area covered by the second recess H2' of this embodiment is also different from the second recess H2 of the first embodiment. The following is a description of the differences between the two, and the similarities between the two will not be repeated.

The first protective pattern layer 116A is disposed between the sealant 130 and the pixel electrode layer 114. The first protective pattern layer 116A covers the first sealant-coated region 110b and the first display region 110a. Unlike the first embodiment, the first protective pattern layer 116A has a convex portion 116b overlapping the pixel electrode 114 in addition to the convex portion 116a overlapping the sealant 130. The convex portion 116b is surrounded by the first recess H1' and covers the pixel electrode 114a. The convex portion 116a surrounds the convex portion 116b and the first recess H1'.

The second substrate 120A of the present embodiment includes a light transmissive substrate 122, a second protective pattern layer 128, and a light transmissive conductive layer 126. The second protective pattern layer 128 is disposed between the second alignment film 160 and the light-transmitting substrate 122. The light-transmitting conductive layer 126 is disposed between the second protective pattern layer 128 and the second alignment film 160. The second recess H2' is located in the second protection pattern 128. The second protective pattern layer 128 covers the second display region 120a and the second sealant-coated region 120b. In the embodiment, the sealant 130 surrounds the second protective pattern layer 128 and the second alignment film 160. The sealant 130 can be directly bonded to the light-transmissive conductive layer 126. In other words, through the arrangement of the second recess H2', the second alignment film 160 does not come into contact with the external environment, and the outside moisture does not easily enter the display 100A through the second alignment film 160. As a result, the reliability of the display 100A can be improved.

In addition, the second substrate 120A may also optionally include a light shielding pattern layer 124. The light shielding pattern layer 124 may be disposed between the light transmitting substrate 122 and the sealant 130 and expose the second display region 120a. However, the present invention is not limited thereto. In other embodiments, the transparent substrate 122 may also be located in the light shielding pattern layer 124. The second display area 120a is exposed between the sealant 130 and the frame seal 130. That is, in other embodiments, the light shielding pattern layer 124 may be disposed outside the surface of the display 100A. In addition, the display 100A of the present embodiment has advantages similar to those of the display 100, and will not be repeated here.

Third embodiment

3 is a cross-sectional view of a display according to a third embodiment of the present invention. Referring to FIG. 3, the display 100B of the present embodiment is similar to the display 100A of the second embodiment, and therefore the same elements are denoted by the same reference numerals. The difference between the display 100B of the present embodiment and the display 100A of the second embodiment is that the area covered by the first recess H1" of the present embodiment is different from the first recess H1' of the second embodiment. Further, the embodiment is The form of the first protective pattern layer 116B is slightly different from that of the first protective pattern layer 116A of the second embodiment. The differences between the two will be described below, and the similarities will not be repeated.

Referring to FIG. 3, the first substrate 110 of the present embodiment includes a germanium substrate 112, a pixel electrode layer 114, and a first protective pattern layer 116B. The first protective pattern layer 116B is disposed between the first alignment film 150 and the pixel electrode layer 114. The first recess H1" is located in the first protective pattern layer 116B. The first recess H1" overlaps the first sealant-coated region 110b and the region 110c between the first display region 110a and the first sealant-coated region 110b. In other words, the first protective pattern layer 116B of the present embodiment does not have the convex portion 116a, but has the convex portion 116b surrounded by the first recess H1". The sealant 130 surrounds the convex portion 116b of the first protective pattern layer 116B and the first alignment. The film 150, and the sealant 130 may be directly bonded to the first protective pattern layer 116B.

As a result, the reliability of the display 100B can be improved. In addition, the display 100B of the present embodiment has advantages similar to those of the display 100A, and will not be repeated here.

Fourth embodiment

4 is a cross-sectional view showing a display according to a fourth embodiment of the present invention. Referring to FIG. 4, the display 100D of the present embodiment is similar to the display 100 of the first embodiment, and thus the same elements are denoted by the same reference numerals. The difference between the display 100D of the present embodiment and the display 100 of the first embodiment is that the position where the first recess H of the present embodiment is formed is different from the position where the first recess H1 is formed. The following is a description of the differences between the two, and the similarities between the two will not be repeated.

Referring to FIG. 4 , the display 100D of the present embodiment includes a first substrate 110D , a second substrate 120 opposite to the first substrate 110D , a sealant 130 between the first substrate 110D and the second substrate 120 , a liquid crystal layer 140 , and The first alignment film 150. The first substrate 110D has a first display region 110a, a first sealant coating region 110b surrounding the first display region 110a, and a first recess H. The first recess H is located at least in a region 110c between the first display region 110a and the first sealant-coated region 110b. The sealant 130 is disposed on the first sealant coating zone 110b. The first substrate 110D, the second substrate 120 and the sealant 130 together surround the liquid crystal layer 140. The first alignment film 150 is disposed between the first substrate 110D and the liquid crystal layer 140 and filled in the first recess H.

In this embodiment, the first substrate 110D includes an array arrangement. The germanium substrate 112 of the plurality of active elements 112a and the pixel electrode layer 114 disposed on the germanium substrate 112. The pixel electrode layer 114 has a plurality of pixel electrodes 114b and 114c disposed in the first display region 110a. The pixel electrodes 114b, 114c are electrically connected to the active device 112a. The pixel electrodes 114b, 114c form an active surface S. The first recess H is recessed with respect to the active surface S. In the embodiment, the first recess H may be formed in the first protective pattern layer 116C. In addition, a color filter layer (not shown) may be further disposed on the pixel electrode layer 114 of all embodiments of the present specification. The second substrate of all embodiments of the present specification may also have no recess. In other words, the second substrate of all embodiments of the present specification may further include a full-surface coated alignment film that can cover a surface of the second substrate flatly.

FIG. 5 is a top plan view of the first substrate of FIG. 4. FIG. Referring to FIGS. 4 and 5, the pixel electrode may be divided into a plurality of display pixel electrodes 114b and a plurality of black pixel electrodes 114c. The display pixel electrode 114b is for displaying a picture, and the black pixel electrode 114c is operated to cause a black screen to appear in a region corresponding to the black pixel electrode 114c in the display 100D. The black pixel electrode 114c surrounds the display pixel electrode 114b. The orthographic projection of the first recess H on the active surface S is located between the orthographic projection of the sealant 130 on the active surface S and the black pixel electrode 114c.

The first recess H of this embodiment also has the effect of limiting the distribution range of the first alignment film 150. In detail, the first alignment film 150 of the present embodiment is not easily distributed to the first sealant coating region 110b of the predetermined coating sealant 130 in combination with the dropping method of the injecting PI. In other words, the sealant 130 is not easily formed on the first alignment film 150, and the outside moisture is not easily transmitted through the first alignment. The film 150 enters the display 100D, thereby increasing the reliability of the display 100D. In the present embodiment, the first recess H may be formed using an etching process. The first recess H may be a V-shaped groove (v-groove). However, the present invention does not particularly limit the shape of the first recess H. In other embodiments, the first recess H may be a cavity, a slide or a crater. The shape of the first recess H may depend on actual needs.

In addition, since the edge 150a of the first alignment film 150 is liable to cause display defects due to unevenness of the boundary, if the edge 150a of the first alignment film 150 can be positioned in the first recess H, the problem of poor display can be obtained. improve. In the present embodiment, this can be achieved by appropriately arranging the positions of the hydrophilic film and the hydrophobic film. Specifically, the hydrophilic film 192 may be disposed between the active surface S and the first alignment film 150. In other words, the hydrophilic film 192 may be formed in the first display region 110a. The hydrophobic film 194 can be disposed in the first recess H. By the arrangement of the hydrophilic film 192 and the hydrophobic film 194, the edge 150a of the first alignment film 150 is more easily formed in the first recess H, and the problem of poor display described above can be improved. Figure 6 shows the first recess of Figure 4 and the first alignment film. Referring to FIG. 6, in the embodiment, the hydrophobic film 194 may be a nanostructure. However, the present invention is not limited thereto. In other embodiments, the hydrophobic film 194 may be a film coated on the active surface S, and the material of the film may be cerium oxide (SiO ₂ ), aluminum oxide (Al ₂ O ₃ ) or Other suitable materials. Further, the chemical material forming the hydrophobic film 194 may be silanes, acids, alcohols, or a combination thereof.

In summary, in the display of one embodiment of the present invention, the first alignment film is disposed in the first substrate to limit the distribution range of the first alignment film, and The sealant is not easily coated on the first alignment film. In this way, the external moisture is not easily entered into the display through the first alignment film, thereby making the display more reliable.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the invention, and any one of ordinary skill in the art can make some modifications and refinements without departing from the spirit and scope of the invention. The scope of the invention is defined by the scope of the appended claims.
