초록 ▼

A data processing apparatus has a first processing unit for processing an input data, a second processing unit responsive to the data processed by the first processing unit for executing a processing dependent on the data and producing a display data, and a display unit having a display drive unit and a display device for displaying the display data. The second processing unit is selectively inactivated and activated under control of the first processing unit to reduce power consumption in the second processing unit. The display drive unit is also selectively inactivated and activated under control of the first processing unit to reduce power consumption in the display unit. The display device has a memory function that maintains its display image even when supply of a display drive signal from the display drive unit is stopped, so that a latest image before inactivation of the second processing unit and/or the display drive unit for power consumption reduction is visible by an operator during the inactivated and low power consumption state of the apparatus.

대표청구항 ▼

What is claimed is: 1. A data processing apparatus comprising: a backlight unit for emitting backlight; a liquid crystal display unit for displaying text data, the liquid crystal display unit being able to operate in a transparent display mode for transmitting the backlight and a reflection display mode for reflecting outside light; and a text data input unit for entering text data, wherein the backlight unit is turned off and the liquid crystal display unit enters into the reflection display mode when entry of the text data is absent for a first predetermined period of time in the transparent display mode, wherein the text data is continuously displayed during a transition from the transparent display mode to the reflection display mode, and during a transition from the reflection display mode to the transparent display mode, wherein, when entry of the text data is absent for a second predetermined period of time, the data processing apparatus enters a power supply stop mode, in which a power supply is disconnected from the liquid crystal display unit, and a sign is displayed on the liquid crystal display unit indicating that the data processing apparatus is in the power supply stop mode, wherein the sign which is displayed on the liquid crystal display unit comprises text data; and wherein the display of the sign is maintained on the liquid crystal display unit after the power supply is disconnected from the liquid crystal display unit. 2. The data processing apparatus according to claim 1, wherein upon receiving the text data in the reflection display mode of the liquid crystal display unit, the backlight unit is turned on and the liquid crystal display unit undergoes a transition from the reflection display mode to the transparent display mode. 3. The data processing apparatus according to claim 1, further comprising a first processor and a second processor, wherein the second processor is able to perform a greater amount of processing than the first processor, and wherein the liquid crystal display unit operates in the transparent display mode when an amount of processing for the text data is greater than a predetermined amount, and operates in the reflection display mode when the amount of processing for the text data is less than the predetermined amount. 4. The data processing apparatus according to claim 3, wherein, when the amount of processing for the text data is less than the predetermined amount, the second processor is stopped and the first processor remains activated. 5. The data processing apparatus according to claim 3, wherein the first processor performs character input processing and the second processor converts Japanese characters into Chinese characters. 6. The data processing apparatus according to claim 1, wherein the text data is the word OFF.
