Abstract
The utility model discloses a high effective uniform temperature field double heated liquid crystal display, which is characterized by comprising a heating controller, heating wires or heating chips, a heating film arranged at the back of a liquid crystal panel and a temperature sensor, wherein the heating film, the heating wires or the heating chips and the temperature sensor are connected with the heating controller. The high effective uniform temperature field double heated liquid crystal display can ensure that the liquid crystal panel is uniformly heated and has stable displaying effect.
Description
Technical field
The utility model belongs to electronic technology field, relates to the LCD of a kind of high-level efficiency, the compound heating of homogeneous temperature field.
Technical background
The type of heating that present LCD is used is to take heating film or heating glass mode.These two kinds of type of heating all can not make liquid crystal panel obtain to add thermal effect preferably, heats inhomogeneously, and deviation can appear in contrast during the liquid crystal panel demonstration.Therefore, be necessary existing LCD heating arrangement is improved.
The utility model content
The purpose of this utility model is the shortcoming that overcomes prior art, the LCD of a kind of high-level efficiency, the compound heating of homogeneous temperature field is proposed, the LCD of this high-level efficiency, the compound heating of homogeneous temperature field can ensure the liquid crystal panel homogeneous heating, and display effect is stable.
Technical solution of the present utility model is as follows:
The LCD of a kind of high-level efficiency, the compound heating of homogeneous temperature field is characterized in that, comprises heating controller, heater strip or heating plate, is arranged on the heating film and the temperature sensor at the liquid crystal panel back side; Described heating film, heater strip or heating plate all are connected with heating controller with temperature sensor.
Described heater strip around or heating plate LCD panel be provided with.
Described heating controller is single-chip microcomputer or DSP.
Beneficial effect:
The LCD of high-level efficiency of the present utility model, the compound heating of homogeneous temperature field, liquid crystal panel temperature by sensor, control heater strip or heating plate and heating film heating by temperature controller according to detected temperature again, ensure the liquid crystal panel temperature stabilization, therefore, LCD heating uniformity under low temperature environment is good, phenomenons such as colour cast, brightness be inconsistent can not occur.
The LCD of this high-level efficiency, the compound heating of homogeneous temperature field adopts compound heating to liquid crystal panel, homogeneous heating heats respond wellly, and the mode that adopts heating film and heater strip to match heats, liquid crystal panel and periphery heat more comprehensively better effects if.
Description of drawings
Fig. 1 is an electric theory diagram of the present utility model;
Number in the figure explanation: 1-temperature sensor, 2-heater strip (or heating plate).
Embodiment
Below with reference to figure and specific implementation process the utility model is described in further details.
Embodiment 1: as Fig. 1, the LCD of a kind of high-level efficiency, the compound heating of homogeneous temperature field comprises heating controller, heater strip or heating plate around the setting of LCD panel, the heating film that is arranged on the liquid crystal panel back side and temperature sensor; Described heating film, heater strip or heating plate all are connected with heating controller with temperature sensor.Described heating controller is a single-chip microcomputer.
When low temperature environment need heat, temperature controller sent signal heating film and heater strip or heating plate is carried out temperature control.
This compound even heating fluid crystal display performance such as following table:
