Chen said since starting volume production of AMOLED panels in May, CMEL has been actively sampling the products with clients. As validation by major international clients will take longer, CMEL expects shipments to see a significant increase in the fourth quarter, Chen added.
Taiwan"s Chimei Innolux Corp, a maker of liquid-crystal displays (LCD), recently filed suit in the United States against Sony over alleged patent infringement. A similar complaint was also filed in Beijing No 2 Intermediate People"s Court. The lawsuit came after Sony initiated legal proceedings in US district court this past March, claiming that Chimei and Hong-Kong-listed LCD monitor maker TPV Technology Ltd infringed on its patents in making televisions and computer monitors. In its lawsuit, Chimei Innolux is seeking to halt the sale of all Sony products in the United States - including Bravia televisions and its Cybershot digital cameras and digital photo frames - and is asking for compensatory damages. Does this lawsuit have merit? Is the compensation requested material? Should Sony investors be concerned?
In a recent response, representatives from Chimei Innolux noted that "their filing is completely unrelated to Sony"s earlier complaint against it. Corporate officials noted that they were committed to protecting their intellectual property, their industry partners, as well as their customers." Chimei Innolux recently underwent a three-way merger, one that significant strengthened and diversified their intellectual property portfolio. In fact, Chimei Innolux, is itself a new shell company - one that was formed this past March by the merger of Chi Mei Optoelectronics Corp, Innolux Display Corp and TPO Displays Corp. Together, these companies supply panels and partially assembled screens for use in TVs, computer monitors and other electronics products.
While Chimei"s actions might come as a shock to industry outsiders, investors should not be surprised. In fact, this new lawsuit follows Chimei"s recent patent battles with Acer, Hewlett-Packard, HTC and Apple; battles, that attempted to block competitor production and sales. Interestingly enough, in the high stakes world of technology and intellectual property development, it seems that patent litigation has become a viable way to snag or block competitors, particularly when those competitors threaten niche markets, look to other suppliers, or consider significant vertical integration which threatens a producers revenue stream.
While it will be interesting to watch the outcome of the Chimei lawsuits, it is important to step back and recognize that other significant players are invested in the lawsuits outcome. For example, Foxconn Technology Group, a controversial company that has recently been in the news due to labor issues (and one which currently maintains a vast majority of the patents for Taiwanese component products), recently purchased a major stake in Chimei Innolux. As Foxconn has extended its business along the industrial chain from component making to the sale of complete products, many are beginning to question whether this lawsuit is being pushed by Foxconn with the goal of disrupting foreign competition while insulating its competitive advantage in the market. In fact, one could argue that the motivation for the lawsuit could stem from Foxconn"s desire to seek more LCD orders for Chimei Innolux"s products from Sony and other manufacturers. While it is too early to identify the specific intentions, or predict whether the outcome of this lawsuit will be material for Sony or other technology manufacturers, investors in technology companies need to maintain their awareness and take note of this important trend. Moreover, while Chimei could have only chosen to sue Sony within China, the decision to sue Sony in both the US and China shows how aggressively Chimei and Foxconn are ready to use their patents to secure share, or, more likely, to use the lawsuit to leverage Sony"s cooperation in the supply chain, particularly on the Chinese mainland.

With the progress in modern visual information technologies, the liquid crystal display (LCD) has been widely applied to the display screen of consumer electronic products, such as mobile phones, notebook personal computers, personal computers (PCs) and personal digital assistants (PDAs). However, as the LCD panel in an LCD device is incapable of emitting light, a backlight module is required to be disposed under the LCD panel to provide the light source for the LCD panel, thus enabling the LCD panel to display images.
Generally, backlight modules are divided into direct type backlight modules and side incident type backlight modules. The direct type backlight modules are usually applied to large-sized LCDs, whereas the side incident type backlight modules are usually adopted in small-sized LCDs.
Since a thick and heavy light guide plate 130 is adopted in the side incident type backlight module 100, the side incident type backlight module 100 has the problem of overweight. Furthermore, if the side incident type backlight module 100 is applied to large-sized LCDs, the disadvantages of low yield rate and tendency to warping in large-sized light guide plates 130 would arise.
There is a need for a backlight module and/or a liquid crystal display (LCD) which is flexible and does not require a light guide plate or a diffusion plate.
In yet a further aspect, the invention further provides an LCD including an LCD panel and a backlight module of any of the types disclosed above. The backlight module is disposed under the LCD panel.
FIG. 2C is a schematic view illustrating the relative positions of the films in the backlight module of FIG. 2A. The support(s) and the fasteners of the backlight module are not illustrated in FIG. 2C. Referring to FIGS. 2A and 2C, the retarder 350 has a plurality of retarding regions 352 and at least one non-retarding region 354. Light A provided by the light source 340 penetrates the second reflective type polarizer 360 through the functioning of the retarding regions 352. A method for forming the retarder 350 includes, for example, selectively printing a retarding material on a transparent film. An area printed with the retarding material defines the retarding region 352, whereas an area without the retarding material defines the non-retarding region 354. In the present embodiment, a total area of the retarding regions 352 per unit area on the retarder 350 increases, preferably gradually, as the retarding regions are farther away from the light source 340. The result can be achieved by several different designs. For example, as illustrated in FIG. 2C, an area of each of the retarding regions 352 gradually increases as the retarding region gets farther away from the light source 340. Alternatively, the areas of the retarding regions 352 are the same, but the number of the retarding regions 352 per unit area gradually increases as the retarding regions are farther away from the light source 340.
According to the aforementioned description, the backlight module 300 of the embodiment produces a surface source of uniform luminance by using the combination of the reflection sheet 310, the first reflective type polarizer 320, the retarder 350 and the second reflective type polarizer 360, and a thick and heavy light guide plate is not required unlike the conventional side incident type backlight module. Therefore, the backlight module 300 has the advantages of thinner thickness and lighter weight. Furthermore, the backlight module 300 does not employ any elements that are difficult to warp, such as a light guide plate or a diffusion plate, so that it can be easily designed as a flexible type backlight module. In addition, when the backlight module 300 is of a larger size (such as those applied in large-sized LCDs), since it does not have a light guide plate, the problems of low yield rate and tendency to warping in large-sized light guide plates can be avoided.
FIG. 3 is a schematic view illustrating relative positions of films in a backlight module according to another embodiment of the invention. A support and fasteners of the backlight module are not illustrated in FIG. 3. Referring to FIG. 3, in the present embodiment, a second reflective type polarizer 360aand a first reflective type polarizer 320aare circular polarizers. A circular polarization direction 324 of the first reflective type polarizer 320ais opposite to a circular polarization direction 364 of the second reflective type polarizer 360a. For example, one of the circular polarization directions 324 and 364 is clockwise, whereas the other is counterclockwise. Circular polarization directions of the light A are opposite before and after passing through the retarding regions 352. Thus, the light A passing through the retarding regions 352 may continue to pass through the second reflective type polarizer 360a. The light A passing through the non-retarding region 354 is reflected by the second reflective type polarizer 360a. A portion of the light A reflected by the second reflective type polarizer 360ais reflected by the reflection sheet 310 and thus can be utilized again after penetrating the retarder 350 and the first reflective type polarizer 320a. Further, a ¼ wavelength retarder 390 may be disposed on the second reflective type polarizer 360a. The light A coming from the second reflective type polarizer 360achanges from a circular polarizing state to a linear polarizing state after penetrating the ¼ wavelength retarder 390. This feature is suitable for LCD panels whose bright or dark state is determined by whether linear polarizing light passes through the LCD panels or not, such as the twisted nematic (TN) LCD panel, the in-plane switching (IPS) LCD panel, or the vertical alignment (VA) LCD panel.
FIG. 11 illustrates a schematic view of an LCD according to one embodiment of the invention. Referring to FIG. 11, an LCD 500 of the embodiment includes an LCD panel 510 and a backlight module 520 disposed under the LCD panel 510. The backlight module 520 may be one of the backlight modules 300-300cand 400-400cin the aforementioned embodiments or it may be any other backlight module having the characteristics of the invention. Additionally, the backlight module 520 is disposed with its light-emitting direction towards the LCD panel 510, which means a surface source is provided by the backlight module 520 at its top side adjacent to the LCD panel 510. If the LCD panel 510 is flexible, the whole LCD 500 becomes flexible, too.
FIG. 12 illustrates a schematic view of an LCD according to another embodiment of the invention. Referring to FIGS. 11 and 12, an LCD 500ais approximately the same as the LCD 500. The difference is that the LCD 500afurther includes a first polarizer 530 and a second polarizer 540. The first polarizer 530 is disposed between the backlight module 520 and the LCD panel 510, whereas the second polarizer 540 is disposed on the LCD panel 510. After passing through the first polarizer 530 and the second polarizer 540 respectively, linear polarization directions of light are perpendicular to each other. If the light provided by the backlight module 520 is linear polarizing light, the second polarizer 540 may be removed. The first polarizer 530 and the second polarizer 540 are suitable for LCD panels whose bright or dark state is determined by whether linear polarizing light passes through or not.
In conclusion, the backlight module of disclosed embodiments of the present invention adopts either the combination of a reflection sheet, a reflective type polarizer and a retarder or the combination of a reflection sheet and a selective reflection sheet so as to generate a surface source of uniform luminance, and no light guide plate or diffusion plate is required. Therefore, the backlight module of disclosed embodiments of the invention has the advantages of having thinner thickness and lighter weight. Moreover, the backlight module of disclosed embodiments of the invention does not include any elements that are difficult to warp, such as a light guide plate or a diffusion plate, so that it can be easily designed as a flexible type backlight module. Further, the shapes of the through holes in the films are designed as such that the backlight module of disclosed embodiments of the invention can have better flexibility and, at the same time, the films can still be solidly fastened. Besides, the backlight module of disclosed embodiments of the invention may also be applied in LCDs, and if combined with a flexible LCD panel, would advantageously result in a flexible LCD. In addition, when the backlight module of disclosed embodiments of the invention is applied to large-sized LCDs, since the backlight module does not have a light guide plate, the problems of low yield rate and tendency to warping in large-sized light guide plates can be avoided.
