Un cache-écran d'un écran plat (7B) entouré d'un cadre-support (7), notamment un écran plat mural du type à cristaux liquides (LCD) ou plasma, comporte un verre-miroir (2) monté dans un cadre (1) adapté aux dimensions de l'écran et susceptible d'être solidarisé au ou retenu sur le cadre-support (7) avec le verre-miroir disposé contre l'écran plat (7B). Le verre-miroir (2) porte une couche réfléchissante laquelle laisse passer la lumière émise par l'écran plat (B) quand celui-ci est allumé, et forme un miroir réfléchissant qui cache parfaitement l'écran plat (7B) quand celui-ci est éteint. En outre, le verre-miroir (2) protège l'écran de toute atteinte accidentel.

Protective screen (20) for a monitor (11) of a computer, comprising a filter plate (13) and two lateral panels (22, 23) adapted for fixing the screen (10) on the monitor (11) and for sliding with respect to each other so as to adapt to the width of the monitor. Two loudspeakers (35, 36) are fitted on the lateral panels (22, 23) and may be connected by electrical means to the computer basic unit. Assembly of the protective screen (20) on the monitor (11) automatically effects optimum positioning of the loudspeakers (35, 36) in relation to the user.

An optical filter screen (100) for a visual monitor includes an optical filter supported by a support frame. A pair of adjustable mounting members (120A, 120B) support the support frame from a visual display monitor or similar such that the optical filter is positioned adjacent a display area of the display monitor. Each mounting member includes a stem element (122A) with a first and second end (124A, 126A). A support element (128A) is rotatably engaged with the first end of the stem element so that in a first stop position the support element extends outwardly from the stem element to engage a top surface of the visual display unit. The support element folds down into a second storage position in which it lies substantially parallel with the stem element.

A deflection yoke assembly (120) for a cathode ray tube (130) includes four substantially equally spaced inclined mounting members (100) arranged about the circumference of a mounting ring (22) at the front of the yoke assembly (120). Each mounting member (100) has a plunger (140) which positions the yoke with respect to the funnel portion of the cathode ray tube (130). A continuously unidirectional restricting means (160) prevents the plunger (140) from withdrawing from the funnel portion of the cathode ray tube (130). A release cylinder (170), which is coaxial with the sleeve (140) and plunger (150), releases the unidirectional means, which may be an internally toothed washer (160), in order to provide capability for readjustment.
摘要:
A glare filter for a computer monitor having a support element with a first side and a second side, and a frame with a first side and a second side. The first side of the frame is pivotably connected to the first side of the support element, and the second side of the frame is pivotably connected to the second side of the support element. The glare filter also has a filter medium secured to the frame and at least one clip for removably attaching the support element to the computer monitor. A grounding clip for a glare filter having a frame with a slot is also disclosed comprising a curved end portion to be inserted into the slot of the frame at least a portion of which contacts the filter medium.
摘要:
Electromagnetic interference ("EMI") is reduced in a CRT video display system by spreading-out the EMI-producing spectra present in the video pixel data and/or clock signals. A clock dropping circuit coupled between the display generator main oscillator and the timing generator periodically phase-modulates the timing generator clock signal such that it comprises N phases, where N≥2. As a result, each horizontal line of video data and the horizontal synchronization signals is phase shifted. This dual-shifting effect eliminates display image distortion that would result if only the video signal were shifted. Video distortion is further minimized by deriving the horizontal and vertical synchronizing signals from a common constant clock. EMI energy associated with each clock harmonic is spread by a frequency amount Af proportional to the rate of phase change in the clock signal, the rate of phase change exceeding half the bandwidth f m of a standard EMI measurement reference window. This disperses adjacent spectral energy sufficiently so the reference window measures but one, decreased, amplitude at a time.

The present invention relates to a mechanism for installing a picture tube of a TV set or monitor so that the picture tube has been fixedly attached to a frame part (3) on which a desired number of friction sleeves (2) have been installed. In front of the picture tube a mask (1) has been installed on which sleeves (4) have been formed at points corresponding to the friction sleeves (2) of the frame part (3), whereby the sleeves (4) will axially enter the friction sleeves (2) and hold the mask in place by friction.
