Abstract:
An electronic apparatus having a heat discharging structure which divides light driving sources into driving devices generating high heat and driving devices generating relatively low heat, and a backlight unit for the electronic apparatus is provided. The electronic apparatus includes a liquid crystal display (LCD) panel; a light source module having a light source illuminating the LCD panel and a first board mounting the light source thereon; and a driving module having a first driving device mounted on the first board and a second driving device disposed separately from the first driving device.
Abstract:
An image projection apparatus for adjusting a white balance in consideration of a temperature of an LED and a method thereof. The image projection apparatus includes a light source unit to sequentially emit lights generated by a red (R)-light emitting element, a green (G)-light emitting element, and a blue (B)-light emitting element. Light levels of the R-light emitting element, the G-light emitting element and the B-light emitting element change depending on changes in temperature. An image generation unit generates an image using the lights sequentially emitted from the light source unit and projects the image. A driving unit drives the light source unit and the image generation unit. A temperature sensor measures a temperature of the light source unit, and a controller controls a driving operation of the driving unit based on the temperature of the light source unit measured by the temperature sensor to adjust a white balance of the image projected from the image generation unit.
Abstract:
An image control device using color coordinates includes a measurement color storage part for storing measured color coordinates of certain images differently displayed depending on the characteristics of image realization devices; a reference color storage part for storing reference color coordinates of the certain images; and a compensation part for compensating input image signals reflecting an extent of changes between the measured color coordinates and the reference color coordinates. If input images are compensated by the device, compensated images using reference color coordinates can be at once provided.
Abstract:
An apparatus and method is disclosed for controlling a display driving pulse to drive an LED display. In one embodiment, an RGB signal is received and a period during which all the LEDs are switched off is detected. Also, the period during which an image is not being displayed is also detected. The driving time of each LED is then extended by the detected periods so that the lighting time of the LED is extended, and brightness of the display as a whole is improved using the LED system.
