摘要： In a backlight using an LED, area control is performed such that the backlight is lit only in the bright area of the screen and the backlight is not lit in the dark area. The temperature change in the light emission efficiency of the LED is large. The temperature of the lit LED is high in area control, so that when a completely gray screen is displayed after the area control, the light emission efficiency of the LED decreases in the previously illuminated area, resulting in the occurrence of uneven brightness. The present invention prevents the uneven brightness of the screen in area control, by reducing the temperature change in the light emission efficiency of the LED to 5% or less, and more preferably 3% or less, in a temperature range of 50° C. to 90° C.

摘要： A reflecting plate in form of dual half-ellipses comprises a first ellipse having a first focal point and a second focal point, and a second ellipse having a first focal point and a second focal point. The first ellipse and the second ellipse commonly share the first focal point. A cross-section of the reflecting plate is designed in such a form that the dual half-ellipses are aligned with each other, and that contours of the first ellipse and the second ellipse are divided by a straight line, which includes the commonly shared first focal point and the other focal points. The reflecting plate encloses the line light source by the dual half-ellipses and reflects a light from the line light source toward the diffusion plate arranged above by specular reflection and by diffused reflection. As a result, uneven brightness is eliminated at the boundary of the reflecting plate designed in form of dual half-ellipses.

摘要： A matrix panel display apparatus includes plural signal lines and plural scanning lines intersecting each other and, near each intersection point, a picture element including a picture element electrode, a counter electrode, a display medium disposed between the picture element electrode and the counter electrode, and a transistor for applying image signals from the signal line to the picture element electrode. The transistor is controlled in response to scanning signals received on a scanning line. An auxiliary signal generating circuit generates auxiliary signals for increasing effective voltages of the image signals and applies the auxiliary signals to the picture elements while each of the transistors is in a non-conducting state and each of the picture elements is not selected. Preferably, the auxiliary signal generating circuit applies the auxiliary signals to the picture elements during a predetermined period in which all of the transistors are in the non-conducting state and none of the picture elements is selected.
