Abstract: A display apparatus (100) comprising a display screen (110) and a backlight assembly (120) is provided. The backlight assembly (120) comprises a distributed light source (122, 124) and a light guide plate (126) having at least two lateral edges. The light guide plate (126) and the distributed light source (122, 124) are arranged such that the light emitted by the distributed light source (122, 124) is edge-coupled into the light guide plate (126) for being forward projected onto the display screen (110) to illuminate the display screen (110) from back. The distributed light source (122, 124) is mounted on a heat sink structure (130). The heat sink structure (130) comprises a plurality of spaced-apart heat dissipating plates (136). Each heat dissipating plate (136) functions as a heat dissipation fin, is in thermal communication with the distributed light source (122, 124) and spans between the two lateral edges of the light guide plate (126).

Abstract: A display apparatus comprising first and second liquid crystal display (“LCD”) modules, each LCD module comprising an LCD cell and a backlight arrangement which is arranged to provide backlight illumination to an image display screen of the LCD cell; wherein a ventilation channel is defined between the two LCD modules; characterized in that air-moving arrangements are provided to move air across the ventilation channel to dissipate heat generated by the backlight modules during operation. Such arrangements facilitate the implementation of ultra-bright LCD displays which could function well under bright sunlight while alleviating over-heating issues due to a high intensity of backlight illumination.

Abstract: A delay locked loop controls a plurality of delay blocks included in a delay line and thus generate a plurality of clock signals which have a frequency obtained by multiplying a frequency of a reference clock signal, an accurate phase delay, and a constant duty cycle. The delay locked loop calculates an initial delay value and applies it to the delay blocks, thereby preventing harmonic locking and reducing locking time.
