摘要： The display device of this invention has two types of DA converter for converting a digital image signal to an analog image signal; a first DA converter disposed in the peripheral area of a plurality of pixel elements and a second DA converter disposed within each of the pixel elements. The first DA converter converts the upper four-bit of a six-bit digital image signal and the second DA converter converts the remaining lower two-bit. This enables the simplification of the peripheral circuits of the pixel element, preventing size increase of the framing area of the display panel, while achieving the multiple-depth display with an increased number of the bits of the DA converter. In the display device with the built-in DA converter, the multiple-bit can be achieved while preventing the increase in the circuit size.
摘要翻译：本发明的显示装置具有将数字图像信号转换为模拟图像信号的两种类型的DA转换器; 设置在多个像素元件的周边区域中的第一DA转换器和设置在每个像素元件内的第二DA转换器。第一个DA转换器转换六位数字图像信号的高四位，第二个DA转换器转换其余的较低的两位。这使得能够简化像素元件的外围电路，防止显示面板的成帧区域的尺寸增加，同时通过DA转换器的位数增加来实现多深度显示。在具有内置DA转换器的显示设备中，可以实现多位，同时防止电路尺寸的增加。

摘要： A display device has a drain drive circuit, to which a horizontal output enable signal is applied in synchronization with a horizontal scanning signal. The enable signal allows the horizontal scanning signal to be supplied only to the gates of selected sampling transistors. Gate signal lines are also selected by a gate drive circuit. Accordingly, any set of arbitrary pixel elements in the display device are selected for rewriting the signal retained in the pixel elements.

摘要： There is proposed is a method of controlling a flat panel display apparatus for multi-gradation display in which a data determination portion and a subfield control portion are provided. Based on a most significant bit or an upper bit of original image data, it is determined in which one of two or more divided gradation groups the original image data is included, to select a combination of subfields in accordance with a gradation-brightness characteristic of the belonging gradation group. Using a complementary relationship with human visibility, a difference in brightness between the gradations in a low-order brightness region is reduced, and a difference in brightness between the gradations in a high-order brightness region is enlarged. Therefore, a density of brightness is uniformly recognized visually over all the brightness regions, and a good quality of display can be obtained.

摘要： Power consumption in an active matrix type liquid crystal display device having partial display function is reduced. In one frame period, a display area corresponding to first 80 horizontal periods, that is the first line through the 80th line, is set as a partial display area and a display area corresponding to the remaining 239 lines is set as a background display area. And a partial display area control signal ENBSC is set at a low level and an SC inversion drive is performed in the partial display area. The partial display area control signal ENBSC is fixed at a high level in the background display area and all of SC inversion control units corresponding to the background display area halt their operation.

摘要： Test data terminals R-DATA, G-DATA, and B-DATA are provided with respect to video signal lines VL-R, VL-G, and VL-B, via switches SW-R, SW-G, and SW-B, respectively. The switches SW-R, SW-G, and SW-B are turned ON by receiving an H level input signal supplied from a test terminal SW. Thus, a test of a panel is performed before an external IC is connected to the panel. When the external IC is connected to the panel, on the other hand, these terminals used for the test are fixed to an L level, thereby preventing abnormal operations.

摘要： A display device has a power line providing a retaining circuit with a power voltage, which is also used as a storage capacitance line connected to one of the electrodes of a storage capacitor. The storage capacitance line is disposed parallel to gate signal lines in a pixel element of the device. The power line of two inverter circuits, which form the retaining circuit, extends in the direction perpendicular to the storage capacitance line and is connected to the storage capacitance line. This configuration helps to reduce the overall size of the display device.

摘要： A liquid crystal display apparatus includes a liquid crystal display panel having preset display characteristics, such as image brightness and contrast. A luminescent unit is optically connected with the display panel and provides light to the display panel in order to form an image on the display panel. The luminescent unit includes a light collector which collects ambient light and a light source, for generating light when the amount of ambient light is insufficient to generate a clear image. A control circuit is electrically connected to the display panel and automatically varies the preset display characteristics in accordance with the amount of ambient light collected by the light collector.

摘要： The supply voltage to a driving circuit (100) and LCD (200) generated by a power supply circuit (350) is controlled to be periodically turned on and off during a power save mode, using a timer circuit (260) or timer such as a counting circuit. In this manner, during the power save mode, the power consumption can be reduced by turning off the power supply, and, at the same time, the display can be periodically shown without any further manipulation. By suspending the output of the gate selection signals to the display panels before the control to turn off the power supply, the display immediately before the turn off operation can be maintained even after the power supply is turned off.
