Abstract
The utility model discloses a touch type liquid crystal display comprising a liquid crystal display, a backlight module positioned under the liquid crystal display, a main board used for controlling the backlight module, a storage cell arranged on the main board, and a resistive touch screen arranged above the liquid crystal display. The touch liquid crystal display also comprises a thin-film solar cell which is arranged on at least one brim of the touch type liquid crystal display and connected with a voltage converter, and the thin-film solar cell and the voltage converter are connected with the storage cell. The touch liquid crystal display has the advantages that the adopted thin-film solar cell has lower requirement on light and can still generate power under dim light; and furthermore, the touch type liquid crystal display avoids the defects that when being applied to the display, a solar cell which can not obtain a better incident angle of light can not effectively generate power.
Description
Technical field
The utility model relates to a kind of touch type liquid crystal display.
Background technology
The tradition touch type liquid crystal display comprises LCD MODULE, is positioned at the backlight assembly of LCD MODULE below, and the mainboard that is positioned at the backlight assembly below, and this class touch type liquid crystal display is to power by external power supply, and energy resource consumption is big.
The utility model content
The technical problems to be solved in the utility model is in order to overcome the big defective of touch type liquid crystal display energy resource consumption of the prior art, a kind of touch type liquid crystal display to be provided.
The utility model solves above-mentioned technical matters by following technical proposals:
A kind of touch type liquid crystal display, it comprises a LCD, one is used to control the mainboard of this LCD, one is located at the accumulator on this mainboard, an and resistive touch screen of being located at this LCD top, its characteristics are, this touch type liquid crystal display also comprises a thin-film solar cells, this thin-film solar cells is arranged at least one edge of this touch type liquid crystal display, this thin-film solar cells is connected with an electric pressure converter, and this thin-film solar cells is connected with this accumulator with this electric pressure converter.
Wherein, this resistive touch screen is provided with a flexible circuit board, and this flexible circuit board is connected with this mainboard.
Wherein, this thin-film solar cells be arranged at this resistive touch screen around.
Wherein, this electric pressure converter is the DC/DC electric pressure converter.
In the utility model, but above-mentioned optimum condition combination in any on the basis that meets this area general knowledge promptly gets each preferred embodiments of the utility model.
Positive progressive effect of the present utility model is: the thin-film solar cells that the touch type liquid crystal display in the utility model adopts requires lower to light, also can generate electricity well under the condition of the low light level.The defective that can't obtain angle of incidence of light degree preferably when further, the utility model has avoided solar cell to be used on the display and can't effectively generate electricity.

Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
Shown in Fig. 1-2, touch-screen 1 in the utility model is a resistive touch screen, described resistive touch screen is a prior art, its screen body portion comprises a substrate 11, it can adopt glass or organic glass to make, upper surface at substrate 11 scribbles one deck conductive layer 12, above substrate 11, also be provided with one deck through cure process, the plastic layer 13 of smooth anti-scratch, plastic layer 13 and substrate 11 relative one sides scribble one deck conductive layer 12 ', transparent isolating points 16 by many tiny (less than mils) between conductive layer 12 and the conductive layer 12 ' separates, and described conductive layer 12 and 12 ' adopts ITO film (Indium-TinOxide: the indium tin oxide transparent conducting film) make.Surface beyond visible area 14 scopes of resistive touch screen adopts double faced adhesive tape technology to attach thin film solar cell 15.
Shown in Fig. 3 and 4, touch type liquid crystal display in the utility model comprises a LCD 2, LCD 2 is provided with an above-mentioned touch-screen 1, is provided with a mainboard 4 below the LCD 2, also is provided with a flexible circuit board 3 that is connected with mainboard 4 on LCD 2.On mainboard 4, be provided with a backlight assembly, controller 6, one provides the accumulator of the energy for this backlight assembly and controller 6, and a DC/DC converter 5 that is connected with thin-film solar cells with this accumulator, wherein the mode of the power outlet of thin-film solar cells by the FPC crimping goes out pin and is connected on this DC/DC converter.Since intensity of sunshine, the variation of environment and load, and the current/voltage instability of thin-film solar cells output, low-voltage can not get well utilizing the adjusting difficulty of while controller 6 bigger.The electric energy that is produced according to the photovoltaic principle by DC/DC converter 5 voltage stabilizing thin-film solar cells, and this electric energy is transferred to can be the burning voltage of touch type liquid crystal display power supply.Accumulator then is in floating charge state, and the electric energy that above-mentioned DC/DC converter 5 is converted to when sunshine amount is big is except to LCD 2, and backlight assembly outside the power supply of controller 6 even loads, also charges to accumulator; When sunshine amount hour, the energy of accumulator stored will progressively discharge to above-mentioned load electric energy will be provided.
Above-mentioned controller 6 is used to detect the output voltage of thin-film solar cells, selects suitable DC/DC branch road; Detect the magnitude of voltage of accumulator,, select suitable charging modes according to the state-of-charge of accumulator; For accumulator provides charging, over; Control liquid crystal display display effect, demonstration backlight, touch-screen touch recognition.
Again as shown in Figure 2, when finger touch sun power touch-screen, two conductive layers 12 and 12 ' has just had in the position, touch point and to have contacted, and resistance changes, along producing signal on touch-screen X (laterally) and Y (vertically) both direction and this signal being sent into controller.Controller detects this contact and calculates the touch point that (promptly touch location is identified for X, the Y) position of coordinate.
Though more than described embodiment of the present utility model, but those skilled in the art is to be understood that, these only illustrate, and under the prerequisite that does not deviate from principle of the present utility model and essence, can make numerous variations or modification to these embodiments.Therefore, protection domain of the present utility model is limited by appended claims.
