The difference of the screen display of the existing commercial display devices, such as advertising machines, cash registers and other devices, is extremely high, the interface standards of the screens with different sizes or types are different, such as HDMI, EDP, LVDS, VGA, MIPI and the like, and some devices even need double-screen display, and the interface of the double-screen display has no uniform standard. The screen model of the common equipment with the screen is usually determined at the initial stage of product design, then the circuit is designed according to the definition of the screen interface, and the screen model can not be basically changed as long as the product is produced in quantity, so that the equipment with the screen is suitable for mass production of standardized products. However, for products such as advertising machines and cash registers, the amount of products of a single model is small, and the types of the products needing to be adapted to the screen interface are various, and the PCB needs to be redesigned and manufactured for replacing the screen of the products of the type, which wastes time and labor.

Accordingly, the prior art is deficient and needs improvement.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming the not enough of prior art, provide a mainboard structure of quick adaptation display screen interface.

The technical scheme of the utility model as follows: the utility model provides a quick adaptation display screen interface scheme structure, include: the main control board is provided with a first mini PCI-E seat, the first conversion small plate is provided with a first mini PCI-E socket and a first screen interface seat, and the first mini PCI-E socket is inserted into the first mini PCI-E seat.

Further, the first screen interface seat is any one of an HDMI interface seat, an LVDS interface seat, a VGA interface seat, an MIPI interface seat and an EDP interface seat.

Furthermore, a second mini PCI-E seat is also arranged on the main control board.

The screen display device further comprises a second switching small plate, wherein a second miniPCI-E socket and a second screen interface seat are arranged on the second switching small plate, and the second miniPCI-E socket is inserted into the second miniPCI-E seat.

Further, the second screen interface seat is any one of an HDMI interface seat, an LVDS interface seat, a VGA interface seat, an MIPI interface seat, and an EDP interface seat.

Adopt above-mentioned scheme, the utility model discloses can the multiple screen interface of adaptation, and it is wider to have the dual interface suitability, only need choose for use different switching platelet just can realize supporting different screens, need not the redesign mainboard, can accomplish fast and trade the screen operation, be favorable to reduce cost and the material resources of using manpower sparingly.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1 to fig. 3, in this embodiment, the present invention provides a motherboard structure of a fast-adapting display screen interface, including: the main control board 1 and the first small adapter plate 21, be equipped with first mini PCI-E seat 11 on the main control board, be equipped with first mini PCI-E socket 21a and first screen interface seat 21b on the first small adapter plate, first mini PCI-E socket 21a inserts in the first mini PCI-E seat 11. The first screen interface seat 21b may be any one of a video interface seat such as an HDMI interface seat, an LVDS interface seat, a VGA interface seat, an MIPI interface seat, and an EDP interface seat. The main control board can also be provided with a second mini PCI-E seat 12. The scheme may further include a second small adaptor plate 22, where the second small adaptor plate 22 is provided with a second mini PCI-E socket 22a and a second screen interface seat 22b, and the second mini PCI-E socket 22a is inserted into the second mini PCI-E seat 12. The second screen interface seat 22b may be any one of a video interface seat such as an HDMI interface seat, an LVDS interface seat, a VGA interface seat, an MIPI interface seat, and an EDP interface seat. In the scheme, a first mini PCI-E seat 11 and a second mini PCI-E seat 12 of 52 pins are arranged on a main control board 1, an HDMI bus, an RGB bus and an IO line for screen control are respectively led to the first mini-PCI-E seat and the second mini-PCI-E seat on the main control board 1, then the switching small board of a required type, such as an HDMI to LVDS small board, an HDMI to MIPI small board, an HDMI to EDP small board, an RGB to LVDS small board, an RGB to EDP small board and the like, is selected according to requirements, a mini PCI-E socket on the switching small board is inserted into the corresponding mini-PCI-E seat, because different screen interface seats of different types, such as MIPI, EDP, LVDS and the like, are arranged on different switching small boards, the requirements can be met only by selecting or replacing the corresponding switching small board, the whole main control panel 1 does not need to be redesigned, and the main control panel 1 is provided with two screen interfaces to support double-screen display.

Referring to fig. 1 to fig. 6, in the present embodiment, the first small adaptor plate 21 is an HDMI-LVDS small plate, and the first small adaptor plate 21 is provided with a first mini PCI-E socket 21a and an LVDS socket 21 b; the second small switch board 22 is an RGB-to-EDP board, and a second mini PCI-E socket 22a and an EDP interface seat 22 are arranged on the second small switch board 22; in the main control board 1, the HDMI bus and the screen-controlled IO signal line are connected to the first mini PCI-E base 11, the RGB bus and the screen-controlled IO signal line are connected to the second mini PCI-E base 12, the first mini PCI-E socket 21a is inserted into the first mini PCI-E base 11, and the second mini PCI-E socket 22a is inserted into the second mini PC-E base 12, so that the main control board 1 can support the screen of the LVDS interface and the screen of the EDP interface, and accordingly, if different types of screens need to be supported, only the switching platelet with the corresponding screen interface base needs to be replaced according to the screen type.
