Problems solved by technology

[0004] However, the backlight of the current common LCD (Liquid Crystal Display; liquid crystal display) can only be turned on or off as a whole, and the backlight of some areas cannot be controlled separately, and the power consumption of the backlight accounts for most of the power of the entire display. Therefore, if you use the off-screen display function on an ordinary LCD display, even if the non-display area of ​​the LCD display unit does not work, it will consume a lot of power due to the backlight factor, which is basically equivalent to the display being always on, so it cannot Be able to partially display information like an OLED display without affecting the battery life of the mobile phone

Abstract

The application discloses a liquid crystal display device and electronic equipment. Wherein, the liquid crystal display device includes a backlight unit and a liquid crystal display unit stacked, and a liquid crystal lens is arranged between the backlight unit and the liquid crystal display unit; the liquid crystal display unit includes a first display area and a second display area; the liquid crystal lens is in the When the lens is in the state, it is used for focusing the light emitted by the backlight unit to the first display area. The above solution can not only realize the always-on screen display in the LCD, but also ensure that the electronic equipment has sufficient standby performance.

Description

technical field [0001] The present invention generally relates to the field of display technology, in particular to a liquid crystal display device and electronic equipment. Background technique [0002] Electronic devices, such as mobile phones, tablet computers, etc., will turn off the display screen after a period of inactivity to save power and extend battery life. However, when the user needs to check the time or whether there is a new message, etc., the user needs to manually unlock to light up the display screen, which is not convenient enough in operation. [0003] In order to solve the above problems, mobile phones currently using OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) display screens have an Always On Display function. After the screen is locked, the time will be displayed on a small area of ​​the mobile phone display. , unread messages and other information, which is convenient for users to quickly obtain information, and due to the cha...
