Description
Technical field
The present invention relates to a kind of LCD (liquid crystal display device, LCD device), particularly a kind of semitransparent and half-reflective liquid crystal display (transflective LCD device).
Background note
Because the low priceization of LCD and high-qualityization, LCD has been widely used on the communication products such as laptop (notebook), PDA(Personal Digital Assistant), mobile phone and clock and watch.LCD is passive luminous flat-panel screens, that is LCD need add light source so that the light source to be provided.And LCD (hereinafter to be referred as LCD) generally can be divided into reflective (reflective) LCD, penetration (transmissive) LCD and semi-penetration, semi-reflective (transflective) LCD.Reflective LCD is meant that light source is entered in the LCD by panel the place ahead, and has a reflecting surface (as aluminum metal) in the reflective LCD, and light reflects also each object of process LCD inside of back at reflecting surface, to allow the user can watch the display frame of LCD.Penetration LCD has the rear that a backlight is arranged at liquid crystal cells usually, and in order to the emitting incident light line, incident ray can optionally pass through after the liquid crystal cells, in the display frame of the place ahead of LCD.Semi-penetration, semi-reflective LCD can utilize display reflective and penetration display frame simultaneously.
Please refer to Fig. 1, Fig. 1 is the basic structure synoptic diagram of an existing semi-penetration, semi-reflective LCD.As shown in Figure 1, a semi-penetration, semi-reflective LCD10 includes Polarizer on (upperpolarizer) 12, a phase shift films (retardation film) 14, one top glass substrate (upper glasssubstrate) 16, reflects a Polarizer 28 and a module backlight (back light assembly) 30 with electrode (common counter electrode) 18, one layer of liquid crystal molecule 20, a transparency electrode 22, a lower glass substrate 24, a light diffusing sheet 26, altogether.The one side of module 30 wherein backlight is for light tight, and includes a light source 30a, a light guide plate 30b and a light absorption plate (light absorbingplate) 30c.And reflection Polarizer 28 is made up of a multilayer film dielectric layer (multi-layer dielectric film), but and light partial reflection and partial penetration reflection Polarizer 28.
As shown in Figure 1, after surround lighting (ambient light) enters and partly penetrates light reflective LCD 10, component environment light passes each object in the LCD10, and via reflecting Polarizer 28 reflections and then passing each object in the LCD10, relief user 32 can watch image frame, and this display mode is reflective.And when ambient light intensity is not enough, light source 30a in the module 30 backlight just can produce light with the compensate for ambient light intensity, the light that light source 30a produces can partial penetration reflect Polarizer 28 and pass each object in the LCD10, relief user 32 watches image frame, and this display mode is penetration.
Because existing semi-penetration, semi-reflective LCD utilizes the lighttight back side of one side module as light source, so the user only can wherein simultaneously watch image frame from LCD.And this kind semi-penetration, semi-reflective LCD is when being applied in the cover-lifting type mobile phone, if desire allows the user see messages such as caller identification from the two-Way Observations of flip, then must respectively install a slice LCD on the two sides of flip, cost of manufacture height not only thus, more can increase the volume and the weight of mobile phone, not meet the trend of the more compact mobile phone of present making.
Summary of the invention
The object of the present invention is to provide a kind of semi-penetrated semi-reflected liquid crystal display, to allow the user watch image frame in the tow sides of display.
According to purpose of the present invention, the invention provides a kind of LCD, its include one first and one with this first parallel relative second.One front light-source, this first of being located at this LCD; One half-penetration half-reflection liquid crystal display panel includes one first glass substrate, is located between this front light-source and this LCD this second; One second glass substrate is located between this first glass substrate and this LCD this second; And a semi-penetration semi-reflective layer, be located between this first glass substrate and this second glass substrate.This LCD is to reflect mode display frame via this first with one, and penetrates mode display frame via this second with one.
Because the present invention utilizes a front light-source system and a semi-penetrating and semi-reflective liquid crystal display panel, is combined into a semi-penetration, semi-reflective LCD, the user can watch display frame in this semi-penetration, semi-reflective LCD two sides.Therefore, the present invention only needs a slice semi-penetration, semi-reflective LCD promptly to can be applicable to the appliance and electronic (as mobile phone) of pros and cons display frame, therefore can save the manufacturing cost of product significantly, and reduces the volume and the weight of appliance and electronic.
