Abstract

The invention discloses liquid crystal display equipment. The equipment comprises a backboard, a side frame, an upper frame, a module frame, a liquid crystal screen, a circuit board of the liquid crystal screen and a direct illumination-type LED backlight, wherein the direct illumination-type LED backlight comprises a circuit board of an LED chip arranged on the bottom of the backboard, LED chipsarranged above the circuit board of the LED chip, an optical diaphragm arranged between the side frame and the upper frame as well as a drive and control circuit board and a drive and control electronic device of the LED chips; the drive and control circuit board is arranged inside the side frame or between the upper frame and the module frame; and the drive and control electronic device is arranged on the circuit board of the LED chip or integrated on the drive and control circuit board. The liquid crystal display equipment can reduce thickness, and achieves ultra-thin design.

Description

technical field [0001] The invention relates to liquid crystal display technology, in particular to a liquid crystal display device. Background technique [0002] Since the liquid crystal itself does not emit light, in various liquid crystal display devices (Liquid Crystal Display, hereinafter referred to as: LCD) such as liquid crystal displays and LCD TVs, it is necessary to rely on external light sources to provide light with a certain brightness and uniformity to achieve display. The backlight is the light source provider of the liquid crystal display device, which is located behind the liquid crystal screen. [0003] A light emitting diode (Lighting Emitting Diode, hereinafter referred to as: LED) is a semiconductor solid light emitting device. LED is called the fourth-generation lighting source or green light source. It has the advantages of energy saving, environmental protection because it does not contain mercury, long life, and small size. It has been widely used ...
