LED apparatus and field sequential display

Abstract

An LED apparatus and a field sequential display employing same are disclosed. The LED apparatus includes a substrate, a cup structure, and a dividing structure. The dividing structure divides a containing space formed by the cup structure into a first region and a second region. A first blue-light chip and a first package colloidal are disposed in the first region and a second blue-light chip anda second package colloidal are disposed in the second region. A green-light phosphor is mixed in the second package colloidal to completely convert a monochromatic emission spectrum of a second blue-light band of the second blue-light chip into a monochromatic emission spectrum of a green-light band. The green-light phosphor is selected from one of silicate, oxynitride, lutetium aluminum oxide, and calcium scandium oxide. Characteristic difference among chips of different colors of an LED apparatus can be minimized, thereby improving the entire efficiency.

Description

technical field [0001] The present invention is related to light-emitting diodes, in particular to a light-emitting diode device used in a liquid crystal display device, which forms a green or red monochromatic light source by combining a blue light chip with phosphor powder, so as to reduce the gap between chips of different colors in a traditional light-emitting diode device. The difference in characteristics improves its overall efficiency. Background technique [0002] In recent years, with the continuous development of display technology, Liquid Crystal Display (LCD) is undoubtedly the mainstream of flat panel display technology in terms of mass production scale and product application popularity. Among all kinds of liquid crystal displays, color sequential liquid crystal display (Color Sequential LCD, CS-LCD) can meet wide color requirements because it can improve the color gamut and saturation of the system, reduce material costs, and even greatly improve the electro-...

Problems solved by technology

[0006] However, the LED backlight module 20 of the color sequential liquid crystal display needs to have the red LED chip 200, the green LED chip 202 and the blue LED chip 204 at the same time, because the red LED chip 200, the green LED chip 202 and the blue light emitting diode chip 204, these three kinds of light emitting diode chips with different primary colors have different photoelectric and life characteristics, and the efficiency of the green light emitting diode chip 202 is not good, and the red light emitting diode chip 200 is too sensitive to temperature , easily lead to heat decay and color shift, etc., seriously affecting the overall efficiency and service life of the color sequential LCD
