Abstract

The utility model discloses a vertical integrated digital photo frame which comprises a main system board and an LCD that are directly connected with an ACF. According to the utility model, the LCD and the main system board are directly connected through the ACF thereby reducing the number of PCBs of the whole product to one. The redundant PCB material cost and board washing cost are saved. The connecting wire and connector between the system and the LCM can be saved for saving the cost of the part and reducing cost. The vertical integrated digital photo frame only contains one PCB, therefore the PCB can cling to the LCD when a finished product is assembled, so that the thickness of the product is reduced.

Description

A kind of vertical integration formula DPF

Technical field

The utility model discloses a kind of DPF, particularly a kind of vertical integration formula DPF.

Background technology

The diversification of using along with digital product, DPF produce market rapid rising in recent years, the DPF product mainly is to be used for showing digital photograph, it is made up of main system board and liquid crystal display module.Main system board partly is made up of DSP master chip, FLASH, SDRAM, power module and clock control chip etc., it has decks such as the popular SD in present market, MMS, XD, CF, photographic intelligence in master chip will block carries out treatment conversion and becomes digital signal, drive the liquid crystal display module through sequential processing then, photographic intelligence is presented on the liquid crystal module.Please referring to accompanying drawing 1 and accompanying drawing 2, at present, modal DPF is separately design with LCM end and system end all, do connection by FPC and connector between two parts, LCM end and system end respectively contain a PCB, and two PCB on LCM end and the system end are welded with element, do the cost that can increase entire product like this, and the electronic component part short circuit for fear of LCM end and system end in when assembling, intermediate demand leaves bigger space, causes product thicker.

Summary of the invention

At the above-mentioned high shortcoming of mentioning of DPF cost of manufacture of the prior art, the utility model provides a kind of new DPF structure, and it directly is connected with main system board LCD by ACF, saved the cost of a pcb board.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of vertical integration formula DPF, and described DPF comprises main system board and LCD, main system board directly is connected by ACF with LCD.

The technical scheme that its technical problem that solves the utility model adopts further comprises:

Described main system board and LCD be arranged in parallel.

Described main system board comprises central processing module, FLASH, SDARM, deck, clock control chip and LED driver module, FLASH, SDARM and deck are connected on the data terminal of central processing module, central processing module control clock control chip drives LCD shows that central processing module control LED driver module provides backlight.

The beneficial effects of the utility model are: the utility model spare LCD directly is connected by ACF with main system board, thereby the PCB quantity of entire product is reduced to one, save unnecessary PCB fee of material and wash the plate expense, also can save connecting line and connector between system and the LCM, save the expense of this part, reduced cost.Only contain a PCB in the utility model, PCB and LCD can be sticked together fully when therefore assembling finished product, make product thinner.

Below in conjunction with the drawings and specific embodiments the utility model is described further.

Fig. 1 is a DPF structure block diagram of the prior art.

Fig. 2 is a DPF structure block diagram of the prior art.

Fig. 3 is the utility model structure block diagram.

Among the figure, 1-LCD, 2-main system board, 3-ACF.

Embodiment

Present embodiment is the utility model preferred implementation, and other all its principles are identical with present embodiment or approximate with basic structure, all within the utility model protection range.

Please referring to accompanying drawing 3, the utility model mainly comprises two major parts, i.e. LCD1 and main system board 2, and LCD1 and main system board 2 directly connect by ACF3 (being Anisotropic Conductive Film, different in nature conductive film) in the utility model.Main system board 2 comprises central processing module in the present embodiment, FLASH, SDARM, deck, clock control chip and LED driver module, central processing module adopts the DSP master chip, be connected with FLASH and SDARM on the data terminal of central processing module, form single-chip minimum system, deck is connected on the data terminal of central processing module, deck is SD, MMS, deck such as XD or CF, can in deck, insert the SD that has digital photograph, MMS, storage card such as XD or CF, the clock control chip is connected on the data output end of central processing module, central processing module output shows signal is carried out sequential processing rear drive LCD through the clock control chip and is shown, central processing module control LED driver module provides backlight for LCD shows.

The utility model be arranged LCD1 and main system board 2 in parallel when mounted owing to have only 2 PCB of main system board in the system, therefore, LCD1 and main system board 2 can be adjacent to and not worry short circuit problem, thereby make system do slimming.During use, central processing module reads the photographic intelligence in the storage card, and photographic intelligence is carried out treatment conversion becomes digital signal, drives the liquid crystal display module through sequential processing then, and photographic intelligence is presented on the LCD.

The utility model spare LCD directly is connected by ACF with main system board, thereby the PCB quantity of entire product is reduced to one, saves unnecessary PCB fee of material and wash the plate expense, also can save connecting line and connector between system and the LCM, save the expense of this part, reduced cost.Only contain a PCB in the utility model, PCB and LCD can be sticked together fully when therefore assembling finished product, make product thinner.
