A liquid crystal display comprising a backlight module and a liquid crystal display panel is provided. The backlight module comprises a white point source that emits a spectrum of light comprising three peaks. The liquid crystal display panel comprises a liquid crystal layer disposed between a color filter substrate, which comprises a blue filter, a green filter and a red filter, and an opposite substrate. The color filter substrate and the backlight module satisfy the following formulas: ∑ 555 605 BL ( λ ) × CF Red ( λ ) × Δλ ≤ 6.0 ; ( 1 ) ∑ 580 630 BL ( λ ) × CF Green ( λ ) × Δλ ≤ 3.5 ; ( 2 ) ∑ 505 580 BL ( λ ) × CF Blue ( λ ) × Δλ ≤ 3.5 . ( 3 ) Herein, the backlight module has the maximum luminance in one wavelength, with the maximum luminance being set at 1.0. BL (λ) represents the normalized luminance spectrum at each wavelength. CFBlue(λ), CFGreen(λ) and CFRed(λ) represent the transmittance of light at each wavelength passing through the blue filter, the green filter, and the red filter respectively. Δλ is the wavelength interval.

The present invention provides a PoC system (push-to-talk over cellular system) and a method for distributing media data in PoC. The PoC system includes a plurality of clients, a controlling server and a first participating server. In the present invention, since a media receiving port is established in the first participating server which manages at least two clients at the same time, and when a media data is going to be distributed to the clients managed by the first participating server, the controlling server delivers the media data to the media receiving port only. In addition, a multicast addressing technology is further used in the first participating server, therefore, the path of delivering media data is changed and the efficiency of media data delivery during a communication is improved.
摘要:
Maintaining photoresist thickness and uniformity over a substrate that includes various cavities presents problems, such as preventing distortion of features in the resist image close to cavity edges. These problems have been overcome by laying down the photoresist as two separate layers. The first layer is used to eliminate or reduce problems associated with the presence of the cavities. The second layer is processed in the normal way and does not introduce distortions close to a cavity's edge. A first embodiment introduces some liquid into the cavity before laying down the first layer while the second embodiment etches away part of the first layer before applying the second one. Application of the process to the formation of a cantilever that overhangs a cavity is also described.

A method of efficacy anticipation and failure examination for an apparatus is disclosed. The method first establishes an anticipation model, and then trains the anticipation model by calibrating the same using errors obtained between a realistic data and an anticipated data, so as to use the calibrated anticipation model to estimate the performance efficacy of an apparatus or any component in the apparatus, and also to acknowledge if there is any abnormality occurred during the operation of the apparatus or the component.
