Method and device to improve backlight uniformity

A hot spot filter for a light guide is created by taking an image of the light output pattern of an illuminated light guide. The hot spot filter may be a film, a layer, or an additional liquid crystal display dedicated to attenuating bright spots from the light guide. The hot spot filter may be incorporated into the image display by adjusting the grey scale of individual pixels to provide sufficient compensation.

A transmissive display apparatus includes a transparent display panel, a display unit which projects a display light toward a display area of the transparent display panel, a ratio change unit which is provided to the display area, is configured to be capable of changing a light transmittance, and is configured to be capable of changing a ratio of a light quantity of a rear face reflected light reaching a viewpoint relative to a light quantity of a front face reflected light reaching the viewpoint, and a control unit which alternately switches the ratio change unit between a first state and a second state. The ratio change unit lowers, in the first state, the ratio by reducing the light quantity of the rear face reflected light that reaches the viewpoint in comparison to the second state. The light transmittance increases in the second state in comparison to the first state.

Apparatus and method for adaptively adjusting backlight

An apparatus and method for adaptively adjusting backlight are described. The backlight adjusting apparatus includes an intensity-pair distribution device, a brightness compensation module, a frame-adjusting device, a backlight control device, and a backlight module. The intensity-pair distribution device generates a plurality of intensity-pair distribution values of the image frames each composed of a plurality of pixel data. The brightness compensation module computes a dark-state ratio of the pixel data of a current image frame in response to the intensity-pair distribution values, and computes a brightness index of the current image frame in response to the dark-state ratio for generating a brightness compensating signal based on the dark-state ratio and the brightness index. The frame adjusting device adjusts the brightness of the total pixel data of the current image frame in response to brightness compensating signal. The backlight control device updates the brightness index of the current image frame in response to the brightness index of a previous image frame and the intensity-pair distribution values of the current image frame for generating a backlight control signal of the current image frame. The backlight module adjusts the backlight of the module in response to the backlight control signal.

Flat panel display and method of manufacturing the same

A flat panel display includes a vacuum envelope, a cathode, a gate electrode substrate, and a phosphor screen and anode electrode. The vacuum envelope includes a front glass plate which is at least partly transparent and a substrate opposing the front glass plate. The cathode is formed on the substrate and has an electron-emitting source. The gate electrode substrate has an electron-passing hole and is arranged in the vacuum envelope to oppose the substrate to be separate from the cathode. The phosphor screen and anode electrode are formed on a surface of the front glass plate in the vacuum envelope. The gate electrode substrate includes at least an insulating substrate and a gate electrode. The insulating substrate has the electron-passing hole. The gate electrode is formed on the insulating substrate. A method of manufacturing a flat panel display is also disclosed.

Liquid crystal display with superposed contact holes and method of manufacturing the same

A display portion is divided by scan lines and signal lines into sections where pixels are provided. Contact holes each for connecting common wiring and a common electrode together are not formed for all the pixels, but decimated so as to be arranged in zigzags.
