The rear display means and the front display means cooperate with one another to display a combined image. The entire screen of the front display means is capable of displaying a clear image without any disconnection of the image.
Abstract:
The present invention relates to a seed chuck for a single crystal silicon ingot growing apparatus. The seed chuck of the present invention is arranged in the single crystal silicon ingot growing apparatus based on the Czochralski process to hold a seed for growing single crystal silicon ingots. Said seed chuck comprises a seed chuck body having an upper portion with a rope joint part coupled with an ascending or descending rope, and a lower portion with a seed holding portion for accommodating and holding the seed. The seed chuck body has a hole for inserting a cooling pipe which has a vacuumed interior filled with a predetermined amount of refrigerant, and both ends of which are sealed. The cooling pipe is fitted into the insertion hole. The present invention employs a seed chuck with a cooling means to lower the temperature in a seed neck area during a body growing process and increase tensile strength. Whereby, large diameter single crystal silicon ingots can be safely grown.
Abstract:
The present invention relates to a display apparatus comprising front display means (10) and rear display means (50), wherein the front display means (10) and the rear display means (50) are arranged such that an image on the rear display means (50) is visible through a portion of the front display means (10). The front display means (10) comprise: a display panel (20); a front backlight (30) which is arranged behind the display panel (20), and which includes a first light guide plate (36) having a projection window (16) through which an image on the rear display means (50) is visible, first light sources (38) arranged along the circumference of the first light guide plate (36), and a reflection sheet (39) arranged at the rear surface of the first light guide plate (36) to reflect light and having an image hole (18) formed at the region thereof that corresponds to the projection window (16); a rear backlight (40) arranged behind the front backlight (30) and including a second light guide plate (42) corresponding to the projection window (16) and second light sources (44) arranged along the circumference of the second light guide plate (42); and a rear optical shutter (48) arranged behind the second light guide plate (24). The rear optical shutter (48) is made of a transparent material, such that the rear display means and the front display means cooperate with one another to display a combined image. The entire screen of the front display means is capable of displaying an image, without any disconnection of the image, when the rear optical shutter is closed.
Abstract:
The present invention relates to a display device including a sub-backlight, which can prevent the obscure sights caused by light from the light source of the sub-backlight arriving on the object or reel of the main display screen and then reflecting in the frontal direction. The sub-backlight (40) of the present invention includes a second light guide panel (41) having an opening part (42) formed therein corresponding to a transparent window (16), a second light source (43) disposed around the second light guide panel (41), and a polymer dispersed liquid crystal (PDLC) sheet (44) disposed close to the front side of the opening part (42) of the second light guide panel (41).
Abstract:
The present invention relates to a display apparatus comprising front display means (10) and rear display means (50) arranged behind the front display means (10), wherein the front display means (10) and the rear display means (50) are arranged such that images on the rear display means (50) are visible through a portion of the front display means (10). The front display means (10) comprise: a display panel (20) having a front surface and a rear surface on which a first polarizing film (22) and a second polarizing film (28) are formed, respectively, wherein the first polarizing film (22) and the second polarizing film (28) have polarizing axes which intersect each other at a right angle; and a backlight (30) which is arranged behind the display panel (20), and which includes a light guide plate (32) having a projection window (36) through which the rear display means (50) is visible, and light sources (34) arranged along the circumference of the light guide plate (32). The first polarizing film (22) and the second polarizing film (28) of the display panel (20) have respective non-polarizing regions (22b, 28b) formed by cutting off the regions corresponding to the projection window (36). No polarization occurs in the non-polarizing regions (22b, 28b) of the first polarizing film (22) and of the second polarizing film (28), such that an image on the display panel (20) is disconnected, and the image projection capability of the rear display means (50) is improved to achieve improved image sharpness on the rear display means.
