Embodiment Construction

[0014] The present invention relates to the structure of a double-sided liquid crystal display. A double-sided liquid crystal display is made with three substrates, and a thinner double-sided liquid crystal display can be provided.

[0015] Referring to FIG. 1 , it is a schematic diagram of a double-sided liquid crystal display in a first embodiment of the present invention. The first liquid crystal layer 202 is sandwiched between the first substrate 10 and the second substrate 20 to form a first reflective liquid crystal display. The second liquid crystal layer 302 is sandwiched between the first substrate 10 and the third substrate 30 to form a second liquid crystal display. The light source 102, preferably a CCFL or LED, is arranged on one side of the double-sided LCD. The light emitted by the light source 102 is guided by the reflector 104 , the first light guide plate 204 and the second light guide plate 304 , and becomes the light source of the first reflective liquid ...

Abstract

This invention provides a double-sided LCD made of three base plates. The double-sided LCD comprises first reflection LCD and second LCD. The three base plates are separately first base plate, second base plate and third base plate, wherein; the first base plate has first surface and second surface. The first surface of first base plate is orderly located with first reflection layer, first crystal layer, second base plate and first deflection plate to from fist reflection LCD. The second surface of first base plate is orderly located with second reflection layer, second crystal layer, third base plate and second deflection plate to from second reflection LCD.

Description

technical field [0001] The invention relates to a structure of a liquid crystal display, in particular to a double-sided liquid crystal display composed of three substrates. Background technique [0002] With the development of display technology, electronic devices sometimes require two display screens to display data. For example, a foldable electronic device such as a mobile phone or a laptop computer has a display screen on one side of the housing when folded and another display screen for general operation on the other side of the housing when opened. Usually, the two display screens are two back-to-back display screens, which can be made by two sets of liquid crystal display panels. The two groups of liquid crystal display panels need their own backlight sources and liquid crystal panels, so the thickness will be thicker than the original single-sided liquid crystal display. [0003] However, the volume of electronic devices nowadays is developing toward miniaturizat...
