Electronic equipment and liquid crystal display

Abstract

The invention discloses electronic equipment and a liquid crystal display. In the technical scheme, a backlight module of the liquid crystal display comprises a plurality of backlight regions, the plurality of backlight regions can used for independently controlling backlight brightness, so that local dimming is achieved by the backlight module, and a local region can be instantaneously highlighted. Switching between a bright state and a dark state is controlled by a switch panel and a liquid crystal display panel, the dark state can be lower, the bright states of different regions are high, high contrast is achieved, and HDR standard can be achieved by the liquid crystal display.

Description

technical field [0001] The present invention relates to the technical field of electronic equipment, and more specifically, relates to an electronic equipment and a liquid crystal display thereof. Background technique [0002] With the continuous development of science and technology, more and more electronic devices with display functions are widely used in people's daily life and work, which brings great convenience to people's daily life and work, and has become an indispensable essential tool. [0003] A main component of an electronic device to realize a display function is a display, and LCD (Liquid Crystal Display, Liquid Crystal Display) and OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) displays are currently two mainstream displays. The properties of the two displays are shown in Table 1 below. [0004] Table 1 [0005] [0006] According to Table 1, it can be seen that compared with the existing LCD and OLED displays, the contrast of the L...
