Abstract:
A combined mirror and presentation medium includes a presentation member (24) for displaying an image, a presentation body (23) inserted into the presentation member to display an image, a light-emitting unit (25) disposed on one side of the presentation member, a transparent member (21) disposed on one side of the presentation member, and a reflection member (22) deposited between the transparent member (21) and the presentation member (24); a body unit (10) for supporting the presentation medium; a speech recognition drive unit (40) installed inside the body unit (10), configured to detect speech frequencies from a user's speech signals, and driving the system; a control unit (50) installed inside the body unit (10) and configured to control the presentation medium (20) and the speech recognition drive unit (40); and a power source unit (60) for supplying power to the presentation medium, a speaker (70), and the control unit (50).
Abstract:
The present invention relates, in general, to a combined mirror and presentation medium, which allows at least one of various presentation bodies to be inserted thereinto, acts as a mirror such that the inside thereof cannot be seen at normal times, and enables the display of an inserted presentation body to the outside at the time of illumination of the inside of the presentation medium. The object thereof is to provide a combined mirror and presentation medium capable of speech recognition, which provides the functions of a mirror and a picture frame using a reflection plate, thus maximizing the functionality thereof, which enables various types of control by automatically controlling a presentation medium, capable of displaying a presentation body, using a user's speech signals, thus facilitating switching between the function of a mirror and the function of a decoration or information transfer medium, and which allows database information to be represented in response to speech signals from the user, thus efficiently performing combined functions.In order to accomplish the above object, the present invention provides a presentation medium (20) including a presentation member (24) for displaying an image desired to be displayed, a presentation body (23) inserted and installed into the presentation member to display an image, a light-emitting unit (25) disposed on one side of the presentation member, a transparent member (21) disposed on one side of the presentation member, and a reflection member (22) deposited between the transparent member (21) and the presentation member (24) and configured to have a light transmissivity of 40˜60%; a body unit (10) for supporting the presentation medium; a speech recognition drive unit (40) installed inside the body unit (10), configured to detect speech frequencies from a user's speech signals, and driving the system; a control unit (50) installed inside the body unit (10) and configured to control the presentation medium (20) and the speech recognition drive unit (40); and a power source unit (60) for supplying power to the presentation medium, a speaker (70), and the control unit (50); wherein the combined mirror and presentation medium acts as a mirror so as to visually reflect the image of an oppositely located object at normal times at which external brightness is high, and detects the speech signals and brightens the inside of the presentation member at a time of the occurrence of the speech signals from the user, thus enabling the display of the presentation body that is installed inside the presentation member.
Abstract:
A backlight unit comprises a reflecting plate, a light guide plate disposed over the reflecting plate, and a plurality of optic films disposed over the light guide plate. The backlight unit further comprises a lamp horizontally spaced apart from the light guide plate, and a reflecting film corresponding to an upper portion of a space between the light guide plate and the lamp.

Abstract:
Disclosed is a color cathode ray tube which can effectively improve impact resistance by setting a ratio of a curvature coefficient (a/b) of the shadow mask for a long axis to be in a range of about 100,000–135,000, and by setting a ratio of a curvature coefficient (c/d) of the shadow mask for a short axis to be in a range of about 60,000–360,000. Also, in defining ratios between a curvature radius of a center portion of the shadow mask and curvature radiuses along a horizontal direction, a vertical direction, and a diagonal direction, the curvature radius decreases towards the peripheral portions of the shadow mask, thereby improving impact resistance and drop characteristics and thus effectively preventing color purity from being degraded.
Abstract:
A cathode ray tube including a shadow mask which is composed of a effective portion having a plurality of holes through which an electron beam passes and a skirt portion extended approximately in a perpendicular direction to the effective portion, wherein a guiding notch is formed in the skirt portion, the guiding notch includes an end portion which is formed to be opened to the end of the skirt portion and a fixing portion to which a guiding means is fixed, and a width of the end portion is wider than the diameter of the fixing portion. Therefore, the doming effect of the shadow mask is reduced and performance of press processing of the shadow mask can be improved.
