  • Publication number: 20240099074
    Abstract: A display device includes a first display substrate including a light emitting element which emits light of a first color or light of a second color different from the first color, a second display substrate including in order toward the first display substrate, a layer including both a bank layer defining an opening and a wavelength control pattern in the opening, a capping layer covering the wavelength control pattern and the bank layer, and a color absorbing layer which corresponds to the bank layer and blocks the light of the first color and the light of the second color. The capping layer includes a first area corresponding to the color absorbing layer, the bank layer includes a second area corresponding to the color absorbing layer, and the first area of the capping layer is between the color absorbing layer and the second area of the bank layer.

  • Patent number: 11709386
    Abstract: Disclosed is a liquid crystal display device including: a liquid crystal display panel for displaying an image; a backlight unit for irradiating light toward a rear surface of the liquid crystal display panel; a cover bottom formed therein with a space in which the liquid crystal display panel and the backlight unit are installed; and a glass attached to a front surface of the liquid crystal display panel to protect the liquid crystal display panel, wherein the liquid crystal display panel and the backlight unit are spaced apart from each other so that air moves through a space between the liquid crystal display panel and the backlight unit. Accordingly, a sealed space is formed inside the liquid crystal display device, and the air inside the sealed space is circulated, so that thermal equilibrium is induced inside the sealed space.

  • Publication number: 20210181565
    Abstract: A liquid crystal display device including: a liquid crystal display panel for displaying an image; a backlight unit for irradiating light toward a rear surface of the liquid crystal display panel; a cover bottom formed therein with a space in which the liquid crystal display panel and the backlight unit are installed; and a glass attached to a front surface of the liquid crystal display panel by a direct bonding scheme to protect the liquid crystal display panel, wherein the liquid crystal display panel and the backlight unit are spaced apart from each other so that air moves through a space between the liquid crystal display panel and the backlight unit. Accordingly, the liquid crystal display panel attached to the glass is directly cooled, so that thermal deformation of the liquid crystal display panel due to high-temperature radiant heat generated from the glass is prevented.

  • Patent number: 5742127
    Abstract: A system for degaussing a cathode ray tube (CRT) which avoids displaying a distorted picture to the user when a magnetic field is degaussed while the CRT is on. The system of the present invention recognizes when a user has pressed a button to initiate the manual degaussing operation, controls the brightness and contrast of the CRT so that the displayed picture becomes black, degausses the CRT while the picture appears black, and controls the brightness and contrast of the CRT to levels present before degaussing.
