Structure.
Background technique
Existing liquid crystal (Liquid Crystal Display, LCD) display is by lamp luminescence, and light source is by inclined
Tabula rasa is then using liquid crystal molecule, and the arrangement mode of molecule changes the light angle for penetrating liquid crystal, and then these light pass through again
It crosses colored filter to export with another piece of polaroid, wherein thin film transistor (TFT) can control light by changing the voltage of liquid crystal
The intensity and color of line, and then different colors is formed on liquid crystal display panel.However, due to display pattern and backlight design etc. because
Element limits, and display brightness is substantially reduced at big visual angle.
Liquid crystal display is configured as applying electric field in the liquid crystal layer and applying voltages to field and generating electrode, passes through institute
The electric field of generation and the direction for determining the liquid crystal molecule of liquid crystal layer, and the polarization of incident light is controlled, to help to show image.
Conventional liquid crystal is generally divided into three classes, for example, transmission type lcd device, reflection LCD and
Transflective type liquid crystal display.Transmission type lcd device can be configured as by using the backlight being located on rear side of liquid crystal cell and show
Diagram picture.Reflection LCD can be configured as by using natural light outside and show image.Trans-reflecting type liquid crystal
Show that device can be configured as: running in the transmission mode indoors or at the limited dark place of exterior light, by using display member
The insertion light source of part shows image；And run in this reflection mode in the environment of outdoor high illuminance, with outer by reflection
Portion light shows image.By this method, transflective type liquid crystal display can in conjunction with above-mentioned transmission type lcd device and
The structure of reflection LCD.
In liquid crystal display, it is configured as showing the transmission type lcd device of image or saturating by using backlight
Transoid liquid crystal display is mainly used because its display brightness is relatively higher than conventional reflective-type liquid crystal display.
It should be noted, however, that from backlight radiation and what is be incident on polaroid about the 50% of light inhaled by polaroid
It receives, which is typically coupled to the lower part of corresponding liquid crystal display.Thus, remaining about 50% light can be used for showing
Diagram picture.As a result, light efficiency and display brightness may be lower than acceptable.At the same time, with backlight chip size by
Step reduces, and the pixel of display device is continuously improved, and requirement of the people for image quality is higher and higher, it would be highly desirable to improve the high dynamic of picture
Region displays contrast；Wherein, extinction ratio is an important factor for influencing display capabilities, and analyzer is relative to by analyzer
Minimum is known as extinction ratio through light intensity and maximum the ratio between the light intensity that penetrates, and is in simple terms exactly that light beam passes through the light after polarizing film
The ratio of strong minimum value and maximum value.Therefore, it is necessary to a kind of approach, technology that is effective, saving cost is provided to improve
The liquid crystal display device of display brightness, light extraction efficiency.

The two-dimensional quadrature polarization structure of the enhanced region delustring of rate.
In order to solve the above technical problems, the technical solution of the utility model are as follows: a kind of two dimension of enhanced region delustring is just
Hand over polarization structure, innovative point is: including backlight, the backlight include pcb board, WLP packing forms LED chip,
White wall and lower polarizing layer；
With one or more LED chips for a chip unit, the outer side wall of the chip unit is arranged chip list
Member is isolated in interior white wall, and chip unit is isolated into several first quadrate arrays by the white wall；
The lower polarizing layer have it is several be in the second quadrate array polarization unit, and in layer adjacent polarization unit it is inclined
Vibration direction is orthogonal；
The polarization unit is located at the surface of chip unit, and corresponds.
Further, the orthographic projection of first and second quadrate array is overlapped.
Further, it is provided with display module above the backlight, the display module includes liquid crystal layer and upper polarization
Layer, the upper polarizing layer have several polarization units in third quadrate array, adjacent polarization unit in the upper polarizing layer
Polarization direction it is orthogonal, and the polarization direction of one-to-one polarization unit is being just up and down in the upper polarizing layer and lower polarizing layer
It hands over.
Utility model has the advantages that the two-dimensional quadrature polarization structure of the enhanced region delustring of the utility model, backlight
Source is made of Mini-LED or Micro-LED, greatly reduces the thickness of backlight, achieved currently on the market to disappear
The value of light ratio is about 1/1000 or so, and the value can be increased to 1/100000 or so by the utility model, this is greatly improved
Hundreds of times or more can be improved in display capabilities, that is, the resolution ratio shown, simultaneously because each point light source can be with independent control, it can
To increase the HDR performance of display, display subregion effect is more obvious.
