Description
The present invention relates to a kind of LCD panel, but particularly relate to the LCD panel that a kind of two sides shows.
At present, owing to utilize the low consumption electric power of LCD panel, slim light weight, the feature of low voltage drive etc. has been widely used in PC and has done to show usefulness, and and then has been applied in the display screen of mobile communication products such as PDA, mobile phone.
Fig. 1 A, 1B and 1C show the structure of available liquid crystal display board 10, label 11 is represented a liquid crystal cell, is provided with glass substrate, liquid crystal molecule and other materials in it, but its detailed structure and the present invention are irrelevant, and known by those skilled in the art, also seldom explained at this.
On the two sides of liquid crystal cell 11, be respectively equipped with a front polarizer 12 and a back Polarizer 13, liquid crystal cell 11 utilizes front polarizer 12, the back Polarizer 13 of arranged perpendicular by this, and the assortment of the liquid crystal molecule of control liquid crystal cell 11 changes, make the light can be by maybe not passing through, it is black or white that LCD panel 10 is shown, and demonstrate portrait.
On the Polarizer 13 of back a reflector 14 is set, literal, figure etc. can show on the surface at front polarizer 12 places by this, that is, on the arrow A direction in Figure 1B, can see that the literal shown in Fig. 1 C shows on LCD panel 10.
Along with the progress in epoch, a lot of product needed can both be seen literal on the positive and negative two sides of display screen.
For example, shown in Fig. 2 A, 2B, it is a mobile phone 30 that has PDA (personal digital assistant) concurrently, button portion 31 and display part 32 in conjunction with the time, first display screen 33 on the display part 31 can be used as the display screen that mobile phone is used, and when button portion 31 and display part 32 separately the time, second display screen 34 on the display part 32 can be used as the display screen that PDA uses.
Yet, have now when making this series products, all need use two LCD panel, be used for showing respectively the Presentation Function that positive and negative two sides is required, the result not only makes cost improve, and the thickness of product is increased, and does not meet the compact tendency of the day at present.
In view of this, the objective of the invention is to provide a kind of LCD panel, but its two sides shows in order to address the above problem.
But the LCD panel that one aspect of the present invention provides a kind of two sides to show comprises: the liquid crystal cell with first and second; Be arranged at first Polarizer on first of liquid crystal cell; Be arranged at second Polarizer on second of liquid crystal cell; Be arranged at first reflector on the part of first Polarizer; And not to be arranged at second reflector on the part of second Polarizer with the overlapping mode of first reflector.

First embodiment
With reference to figure 3A, 3B, 3C and 3D, but the LCD panel 20 that the two sides of present embodiment shows comprises a liquid crystal cell 21, one first Polarizer 22, one second Polarizer 23, one first reflector 24 and one second reflector 25; Liquid crystal cell 21 is provided with glass substrate, liquid crystal molecule and other materials in it as prior art, and have one first 211 and 1 second 212.
First Polarizer 22 is arranged on first 211 of liquid crystal cell 21, and second Polarizer 23 is arranged on second 212 of liquid crystal cell 21; First reflector 24 is arranged on the part of first Polarizer 22, and second reflector 25 is arranged on the part of second Polarizer 23, and it is not to be provided with the overlapping mode of first reflector 24.
By above-mentioned formation, second reflector 25 is set on second Polarizer 23, and literal, figure etc. can show on the surface at first Polarizer, 22 places by this, that is, on the arrow B direction in Fig. 3 B, can see that the literal shown in Fig. 3 C shows on LCD panel 20; Again, first reflector 24 is set on first Polarizer 22, literal, figure etc. can show on the surface at second Polarizer, 23 places by this, that is, on the arrow C direction in Fig. 3 B, can see that the literal shown in Fig. 3 D shows on LCD panel 20.
Therefore, by same LCD panel, can be at the first half from a display text, and can be from the another side display text in Lower Half, escapable cost alleviates product weight.
If present embodiment is applied in the mobile phone that has the PDA function concurrently shown in Fig. 2 A, 2B, and first with PDA be positioned at same side with display screen, and second with mobile phone be positioned at same side with display screen, can make the surface that first reflector is not set on first Polarizer as the PDA display screen, and the surface that second reflector is not set on second Polarizer can be used as the mobile phone display screen.
It should be noted that in Fig. 3 D the literal of shown literal and Lower Half is reversed left to right on the LCD panel 20, this can recover normal with the literal of its first half by software, because this technology is known by those skilled in the art, omits its explanation at this.
In addition, the display aspect ratio of positive and negative can obtain by the size of adjusting two reflectors.Second embodiment
With reference to figure 4A, 4B, 3C and 3D, but the LCD panel 40 that the two sides of present embodiment shows comprises a liquid crystal cell 41, one first front polarizer 46, one first back Polarizer 42, one first reflector 44, one second front polarizer 47, one second back Polarizer 43 and one second reflector 45; Liquid crystal cell 41 as existing as, be provided with glass substrate, liquid crystal molecule and other materials in it, and have one first 411 and 1 second 412.
On first 411 of liquid crystal cell 41, the first half is provided with first front polarizer 46, and Lower Half then is provided with the second back Polarizer 43; On second 412 of liquid crystal cell 41, the first half is provided with the first back Polarizer 42, and Lower Half then is provided with second front polarizer 47; First reflector 44 is arranged on the first back Polarizer 42, and second reflector 45 is arranged on the second back Polarizer 43; Wherein by finding out among the figure, on left and right directions, first front polarizer 46, the first back Polarizer 42 and first reflector 44 are overlapping, and second front polarizer 47, the second back Polarizer 43 and second reflector 45 are overlapping.
By above-mentioned formation, on the second back Polarizer 43 second reflector 45 is set, literal, figure etc. can show on the surface at second front polarizer, 47 places by this, that is, on the arrow B direction in Fig. 4 B, can see that the literal shown in Fig. 3 C shows on LCD panel 40; Again, on the first back Polarizer 42 first reflector 44 is set, literal, figure etc. can show on the surface at first front polarizer, 46 places by this, that is, on the arrow C direction in Fig. 4 B, can see that the literal shown in Fig. 3 D shows on LCD panel 40.
Therefore, by same LCD panel, can be at the first half from a display text, and can be from the another side display text in Lower Half, and escapable cost alleviates product weight.
If present embodiment is applied in the mobile phone that has the PDA function concurrently shown in Fig. 2 A, 2B, and first with PDA be positioned at same side with display screen, and second with mobile phone be positioned at same side with display screen, can make on first front polarizer as the PDA display screen, and second front polarizer is as the mobile phone display screen.
It should be noted that in Fig. 3 D the literal of shown literal and Lower Half is reversed left to right on the LCD panel 40, this can recover normal with the literal of its first half by software, because this technology is known by those skilled in the art, omits its explanation at this.
Again, the display aspect ratio of positive and negative can obtain by the size of adjusting two reflectors.
Though the present invention discloses as above in conjunction with the embodiments; yet it is not in order to limit the present invention; those skilled in the art can make some and change and retouching, so protection scope of the present invention should be defined by the accompanying Claim scope without departing from the spirit and scope of the present invention.
