Description
Technical Field
The invention relates to the technical field of display, in particular to a liquid crystal display screen.
Background
Most of the lcd panels are backlight type lcd panels, which are composed of a liquid crystal display panel and a backlight unit (BLU). A typical liquid crystal display panel mainly includes a Color Filter (CF) substrate, a Thin Film Transistor (TFT) array substrate, and a polarizer.
In the current liquid crystal display screen products, the driving modes of the backlight unit using the LED light bar as the backlight source mainly include two types:
in the first mode, a power supply wire is arranged on an LED lamp bar (Light-bar), the power supply wire is connected to a main PCBA/FPCA circuit in a Zero Insertion Force (ZIF) terminal (pin) or welding wire mode, and the output current of the LED lamp bar is controlled by a main circuit power supply of a liquid crystal module; the mode is mainly used for products such as mobile phones, flat panels and notebook computers;
in the second mode, power supply wiring of the LED lamp bars is connected to a ZIF terminal of a main board power supply of the whole machine through terminals, and power supplies are respectively provided for the main board and the LED lamp bars through a main power board; the method is mainly used for display screens (monitors) and TV products.
Backlights using micro LED (Mini-LED) light bars have gradually replaced traditional surface-emitting backlights because of their better High Dynamic Range (HDR) control and high dynamic picture contrast. Although the dynamic contrast ratio can be effectively improved and the image quality can be improved by replacing the whole-surface light emitting mode of the traditional backlight source with the micro LED area dimming (Local dimming) partition light emitting mode, the derived problem is that the number of the bonding pads (Pad) connected with the micro LED light bar is more and more along with the increase of the backlight partition.
When the micro LED light bar is used as a backlight source, for a driving mode of a first backlight unit (corresponding to products such as mobile phones, flat panels and notebook computers), a Bonding Pad (Pad) area of the micro LED light bar occupies a larger and larger binding space; the method reduces the occupation of the whole screen space for the compression of the FPC/PCB Layout (Layout) area.
When the miniature LED lamp strip is used as a backlight source, for the driving mode of the second backlight unit (corresponding to display screens and TV products), the terminal (Pin) area of the miniature LED lamp strip can use a Connector (Connector) with a large number of terminals, so that the terminal occupation space is large, and the wiring cost of power supply PCB (Layout) is increased.
Referring to fig. 1, which is a schematic layout diagram of a conventional micro LED backlight unit, the micro LED backlight unit includes a support (frame)10, the support 10 includes a bottom surface and a sidewall that is higher than the bottom surface upward around the bottom surface, a micro LED light bar (not shown) is disposed on the bottom surface of the support 10, a support flexible circuit board 11 that extends beyond the side is disposed on one side of the support 10, the micro LED light bar generally may be composed of micro LEDs arranged in a matrix within an effective display area (AA)12, a light bar pad 13 is disposed on a portion of the support flexible circuit board 11 that extends beyond the side, and the light bar pad 13 may be correspondingly connected to a sub-area routing of the micro LED light bar through an internal routing of the support flexible circuit board 11.
Referring to fig. 2, there is shown an assembly diagram of a conventional liquid crystal display panel. The liquid crystal display screen mainly comprises a liquid crystal display panel and a miniature LED backlight unit correspondingly assembled together with the liquid crystal display panel. The structure of the micro LED backlight unit can refer to fig. 1, which mainly includes a support 10, a support flexible circuit board 11 extending beyond one side of the support 10 is arranged on one side of the support 10, a light bar pad 13 is arranged on a portion of the support flexible circuit board 11 extending beyond the side, a micro LED light bar 14 is arranged on the bottom surface of the support 10, the light bar pad 13 can be correspondingly connected to a partition wire of the micro LED light bar 14 through the internal wire of the support flexible circuit board 11, and a diffusion plate (diffuiser) and a Prism (Prism) assembly 15 are arranged on the micro LED light bar 14. The liquid crystal display panel mainly includes a color filter substrate 20, a thin film transistor array substrate 21, an upper polarizer 22 and a lower polarizer 23, the color filter substrate 20 and the thin film transistor array substrate 21 are disposed opposite to each other up and down to form a liquid crystal cell, the upper polarizer 22 is disposed above the color filter substrate 20, the lower polarizer 23 is disposed below the thin film transistor array substrate 21, one side edge of the thin film transistor array substrate 21 exceeds a corresponding edge of the color filter substrate 20 and is provided with a liquid crystal cell pad 24, the liquid crystal cell pad 24 is used for electrically connecting a main flexible circuit board 25 outside a liquid crystal cell and a wiring line inside the liquid crystal cell, in the prior art, a light bar pad 13 of a support flexible circuit board 11 is generally welded to the main flexible circuit board 25, so as to electrically connect a micro LED light bar 14 with an external driving power supply.
In order to meet the design requirements of the current regional dimming mode, the backlight partitions of the micro LED light bars 14 are continuously increased, which correspondingly causes the area of the bonding region occupied by the light bar bonding pads 13 to be continuously enlarged, thereby bringing about negative effects of increased layout region routing area, increased circuit board routing layer number and/or increased connector cost.
