Abstract

The invention discloses a bistable liquid crystal display screen integrated with an upper light source and a preparation method thereof. The bistable liquid crystal display screen comprises a transparent upper glass substrate and a transparent lower glass substrate, wherein a liquid crystal body is arranged between the upper glass substrate and the lower glass substrate; an opaque film is adheredto the lower glass substrate; an upper light source assembly is arranged on the upper glass substrate; the upper light source assembly is a transparent part, and the upper light source assembly shinesafter being powered on to provide a light source for the liquid crystal body; and the upper light source assembly comprises a transparent light guide plate, a driving module is arranged on one side of the light guide plate, and a plurality of LED point light sources connected with the driving module are arranged on the light guide plate. According to the invention, the liquid crystal display screen can display normally under different ambient light for a user to check.

Description

technical field [0001] The invention belongs to the technical field of display screens, in particular to a bistable liquid crystal display integrated with an upper light source and a preparation method thereof. Background technique [0002] In terms of display technology, the bistable state means that the same display cell can have two different states of bright state and dark state without applying voltage, and it can be maintained continuously. Therefore, as the name implies, it is called dual steady state. The application of such technology in the display will have several advantages, that is, the screen can be memorized without applying voltage, which can effectively reduce power consumption. Under ideal conditions, bistable technology displays can save up to hundreds of times the power consumption compared with traditional liquid crystal display technology. This state is quite suitable for display applications that do not require frequent screen updates. [0003] Bis...
