Description
Technical field
The present invention is relevant for a kind of integrated display module.During this integrated display module work, according to default initial set value to automatically perform the operation of integrated display module.And for the user who only uses the rgb interface display image, do not need again by microprocessing unit (microprocessor unit, MPU) initial set value of the integrated display module of interface setting.
Background technology
The image of LCD (LCD) has preferable contrast and reduces the state that blurs when picture moves, it no matter is little, the advantage such as the low radiation of tool also of right angle demonstration, low power consumption, volume, can both allow the user enjoy best visual environment, the development of LCD technology just in time suits user's demand.Development along with Mobile Communications Unit, the LCD size that is used in Mobile Communications Unit reduces gradually, and comprise the horizontal drive chip on the single LCD module, vertical drive chip, timing controller, frame memory, gamma correction (Gamma) chip and power circuit etc.In this highly integrated display module, many settings or data transmit all must be undertaken by the MPU interface.
For example be applied to have rgb interface and MPU interface simultaneously in the LCD display module of mobile phone.On the conventional art, by outside microprocessing unit by the MPU interface with to setting in the LCD display module.In addition, static image data also is sent to frame memory by the MPU interface and deposits, and further shows on the LCD panel.Dynamic image data by rgb interface being sent to timing controller, then conversion image data and on the LCD panel, showing.In third generation mobile phone, some user only uses rgb interface to come display image, but in order to set setting value such as supply voltage, then must use the MPU interface to carry out the work setting of LCD module.In this case, the user must carry out in addition the operation of setting, if in assignment procedure, during setting value that the relevant LCD of user's misspecification shows, can cause the LCD panel can't display frame.
Summary of the invention
In view of this, in order to address the above problem, fundamental purpose of the present invention is to provide a kind of integrated display module.After integrated display module work, need not automatically perform the operation of integrated display module with initial set value by outside MPU interface.And because of its setting value is stored in the ROM (read-only memory), the user still can freely adjust the image quality of different demands.
For realizing above-mentioned purpose, the present invention proposes a kind of integrated display module, comprises LCD array, LCD driver, LD device and microprocessing unit.LD device is stored the required setting value of integrated display module work.When microprocessing unit is worked at integrated display module, LD device is write the predetermined first setting value that makes.
For realizing above-mentioned purpose, the present invention more proposes a kind of integrated display module, comprises LCD array, LCD driver, interface arrangement and memory storage.Interface arrangement provides the outside rgb interface and the outside MPU interface that are communicated with integrated display module.First setting value and other related setting value of making of the integrated display module work of memory device stores after integrated display module work, need not write initial value to memory storage with this by outside MPU interface.

Embodiment
Embodiment:
Fig. 1 represents the synoptic diagram of an integrated display module of the embodiment of the invention.Integrated display module 1 comprises LCD array 10, LCD driver 11, LD device 12, microprocessing unit 13, time schedule controller 14 and power control unit 15.LCD array 10 has a plurality of pixel cells, is used for display image, and pixel cell is made of crisscross a plurality of sweep traces and many data lines.LCD driver 11 comprises scanner driver 11a and data driver 11b.When scanner driver 11a connects the scan control signal of being exported by time receiving sequence controller 14, scanner driver 11a sends sweep signal, with a plurality of sweep traces of driving LCD array 10 wherein one.When the data controlling signal that data driver 11b reception time schedule controller 14 is exported, data driver 11b exports a plurality of vision signals simultaneously to many data lines.The operating voltage V10 of LCD driver 11 is provided by power control unit 15.
When integrated display module 1 was worked, the initial set value of the integrated display module 1 of microprocessing unit 13 outputs was deposited to LD device 12.Time schedule controller 14 and power control unit 15 couple this LD device 12, and operate according to initial set value, and further determine the display characteristic of LCD array 10 display images according to initial set value.
In the integrated display module 1 of present embodiment, microprocessing unit 13 is set.When integrated display module 1 is worked, export initial set value automatically by microprocessing unit 13, further time schedule controller 14 and power control unit 15 are carried out initial setting.Thus, work back view data only need be sent to time schedule controller 14 by rgb interface (RGB I/F), and the user do not need to carry out extra setting more yet, and the setting that integrated display module 1 is worked reaches optimization automatically.
Fig. 2 represents the synoptic diagram of another integrated display module of the embodiment of the invention.Integrated display module 2 comprises LCD array 20, LCD driver 21, interface arrangement 22, memory storage 23, time schedule controller 24 and power control unit 25.LCD array 20 has a plurality of pixel cells, is used for display image, and pixel cell is made of crisscross a plurality of sweep traces and many data lines.LCD driver 21 comprises scanner driver 21a and data driver 21b.When scanner driver 21a connects the scan control signal of being exported by time receiving sequence controller 24, scanner driver 21a sends sweep signal, with a plurality of sweep traces of driving LCD array 20 wherein one.When the data controlling signal that data driver 21b reception time schedule controller 24 is exported, data driver 21b exports a plurality of vision signals simultaneously to many data lines.The operating voltage V20 of LCD driver 21 is provided by power control unit 25.The initial set value of the integrated display module 2 of memory storage 23 storages.When integrated display module 2 is worked, be couple to the time schedule controller 24 and the power control unit 25 of memory storage 23, operate according to initial set value, and further determine the display characteristic of LCD array 20 display images according to initial set value.
